Background

Katie comes from a wealthy, influential family. Her aristocratic bearing and formal clothing convince Li Wei that she is a noblewoman of particularly high standing. He later suspects that she is the daughter of someone near the top of the Empire, but deliberately avoids asking her identity to preserve his informal cooperation with the forces behind her 16 26.

Her membership in the Royal Family is subsequently established. Li Wei describes her to the Holy Maiden as “probably a princess,” while acknowledging that he does not know the details and that Katie has never explained them. Her precise identity remains unresolved even much later; Li Wei speculates that only the Queen and Princess Louise within the Royal Family may know the full truth 260 524 686.

Her comments about her family are contradictory in tone. Early on, she sulkily claims that they would be delighted if she died; after the Courtesan Killer investigation, she explains that they kept her confined at home for several days. She subsequently resumes accompanying Li Wei, with her family evidently aware of their partnership 9 16 26.

Katie later explains that her relatives are primarily overprotective: she can travel with them for New Year and other events, but they do not want her leaving Fog City alone. She mentions an elder sister and intends to persuade her mother to permit her to accompany Li Wei. By the Sanctuary expedition, Li Wei obtains the Queen’s permission to take her with him 186 648.

Before investigating alongside Li Wei, Katie helped the Pink Lady’s workers by running errands, buying things they could not obtain themselves, and driving away troublesome customers. She disguised herself well enough that Lady Claytie did not recognize her when they later met in formal society 17 19.

Her upbringing includes royal instruction in etiquette, grammar, and dancing. She claims to have had more governesses than she can count on both hands, driving some away through anger and others through beatings. Her hostility stems from her belief that their affection was often performative or motivated by attempts to secure a relationship with someone in her household. Nevertheless, she trusts Mrs. Helen and agrees to help Li Wei find a suitable governess 249 256 750.

Appearance

• Build: Petite and apparently delicate, standing approximately five feet three inches tall 25.
• Features: Fair skin, bright blue eyes, and platinum-blond hair that reaches her waist when worn loose 11 16.
• Hair color distinction: Unlike genuinely white hair, Katie’s platinum blond shows golden tones in the light 104.
• Everyday clothing: A flat cap, long sleeves, and trousers; her hair is normally tucked beneath the cap 16.
• Formal clothing: A white long-sleeved gown, gold-trimmed black cloak, and felt hat for the Glorious Club visit 16.
• Combat accessory: Gleaming silver metal gloves worn during fights 10 25 32.
• Armor preference: Dislikes cumbersome armor and fights the Silver-armored Knights without it, relying on Li Wei to intercept their weapons 667.
• Protective expedition clothing: Wears a gas mask, one-piece raincoat, and rubber boots when entering the potentially contaminated lake-bed temple 447.

Personality

Katie prizes adventure over money. She declines her £2,500 share of the Courtesan Killer bounty, calling it of little use to her, and instead asks to join Li Wei’s next investigation. Her enthusiasm is strongly influenced by adventure stories about knights, underground labyrinths, monsters, and treasure 16 20.

She resents being underestimated and insists that Li Wei address her by name and recognize her ability to fight. Her excitement can make her impulsive: she follows him into Dolittle’s operating room despite instructions to remain outside and volunteers to force open a safe before he stops her. In combat, however, she dodges carefully and waits for openings rather than attacking blindly 9 10 19.

Her bravery has clear limits. Physical monsters excite her because she believes she can defeat them with her fists, but curses, disappearing dolls, and the transformation of people into puppets frighten her deeply. During the House of Death investigation, she clings to Li Wei for reassurance and openly admits that she does not want to enter 25 39 41 45.

Later encounters clarify that her strongest fear is of ghosts and other threats she cannot anticipate or fight normally. She refuses to enter the haunted Academy, explaining that ghosts can appear anywhere and seem unfair to confront. By contrast, she is willing to attack animate dolls and grotesque creatures when they have tangible bodies 246 275 281 386 528.

Katie is compassionate toward vulnerable people. She regrets being unable to do more for the Pink Lady’s workers, is uncomfortable with the prospect of beating a defenseless old man, and remains concerned about locating Elizabeth while the investigation team is trapped in the haunted house 11 19 44.

Her kindness extends to frightened children, animals, and even ghosts. She leaves a biscuit for the dead man who warns them about the City of Eternal Night despite being terrified of him, comforts Alice during Li Wei’s absence, and stops Buck from bullying the Little Mermaid 275 357.

She dislikes formal social life and finds palace company dull and preoccupied with power. She tells Princess Louise that Li Wei is more interesting and treats her naturally rather than stammering at her. She often chooses family celebrations, swimming, or creative play with the children over aristocratic gatherings 204 205 258 344 633.

Her carefree manner does not mean she lacks social education. She understands the importance of observing proper courtesies, including inviting someone to a banquet even when their attendance is uncertain. Her experience in the Lower City also leaves her less sheltered about adult relationships than Li Wei sometimes assumes 531 750.

Katie remains pampered in practical matters. When asked what she would do after running away, she imagines a carefree life in a large house without first considering money or employment. In Sanctuary, she enjoys its monsters and heroic opportunities but has little interest in its inferior domestic comforts 249 653.

Her battle enthusiasm can disrupt plans. She charges the fortress before receiving the intended signal and attacks the blue dragon before it finishes speaking, forcing her companions to improvise. Nevertheless, she also follows Li Wei’s instructions to seek help, retreat, prepare an escape, or evacuate others when the situation requires it 235 368 448 663 673 704.

Abilities & Skills

Exceptional Strength

Katie’s strength greatly exceeds what her small frame suggests. The Holy Maiden eventually identifies her as a Saint, establishing her extraordinary abilities as innate, but their ultimate source remains unexplained. No confirmed numerical strength attribute or ranked advancement is given; the narrator invites readers to infer her tier without assigning a value 25 47 268 524.

• Sends a grown zombie crashing into a wall with one punch 25.
• Throws flamethrower fuel tanks high enough to strike a monster climbing a building 33.
• Smashes attacking dolls with individual punches and hurls a large bookcase onto armed puppet soldiers 45 47.
• While controlled against her will, injures Li Wei’s blocking arm badly enough that his Diagnosis suggests a fracture 47.
• Easily hauls Li Wei off the floor after the final haunted-house battle 48.
• Punches a monster through a thick granite wall, demolishing the wall and rupturing the creature’s body 201.
• Rolls a snowball as tall as a house across an open plain 210.
• Remains effectively unmoved when a winged monster grabs her, then pulls it out of hiding 212.
• Smashes through a storeroom wall and tears an iron cabinet from its mounting to expose a hidden stairway 234 235.
• Destroys the paw of a giant rabbit with a punch and kills a huge serpent by driving its head into the ground 248 249.
• Uproots the black-robed creature’s hidden, church-spanning body by pulling on its tentacles 287.
• Tears a steel vault door a full fist thick from the wall 344.
• Forces open an enormous iron-reinforced stone door while carrying a Mecha-sized flamethrower 447.
• Snaps prison bars and tears apart a thick iron door’s central locking mechanism without transforming or using an obvious spell 483 486.
• Shatters a half-orc’s heavy black-iron battle axe with her fist 650.
• Smashes through a fortress gate more than four meters tall and punches the transformed Butcher through a wall, accidentally killing him 663 665.
• Tosses around a stone statue weighing several tons and later uses a ripped-out pillar as a weapon 686 703.
• Wields a minecart weighing several hundred kilograms as an enormous hammer against underground monsters 743.

Close-Combat Fighting

Katie combines powerful punches with evasive movement, frequently keeping enemies away from Li Wei while he shoots or reloads 10.

• Draws the small monsters’ attention in Dolittle’s operating room, creating clear firing opportunities for Li Wei 10.
• Holds back the larger monster while Li Wei reloads 10.
• Intercepts Maggie during the prepared vampire ambush 32.
• Delivers the blow that frees Henry from his doll-controlled state 44.
• Can predict and announce her own attacks from muscular movement even when an enemy controls her body 47.
• Uses punches, kicks, grappling, and improvised weapons against enemies too large or resilient for ordinary close combat 235 248 249 703 743.
• Exploits her small frame to move through crowded melee engagements and sends opponents crashing into one another 664.
• Can moderate her force sufficiently to leave opponents alive, although enthusiasm or misjudgment can produce much greater damage than intended 650 665.
• Teaches fighting techniques to Alice, Sophia, and the Little Mermaid; these lessons help them handle ordinary troublemakers, but do not reproduce her exceptional strength 650.

Saint Physiology and Unusual Reactions

The Holy Maiden identifies Katie as a Saint after seeing her effortlessly kill a demon. Saints are born with extraordinary abilities and were more common in the Holy Maiden’s era. Their origin is unknown; a proposed connection to the residual ashes of a divine flame remains unproven. The Holy Maiden also senses that Katie differs from an ordinary Saint 524.

• A sorcerer’s spell intended to render her unconscious and place her under his control has no effect 234.
• A winged monster tears her coat without visibly injuring her shoulder 212.
• Parasitic worms react to her presence with extreme terror. Their hosts suffer distress as she approaches, and closer proximity can drive the worms out of their heads 415.
• Feels intense, unexplained disgust rather than fear when encountering a Haunter of the Dark 264.
• Remains active during the dragon battle when its roar overwhelms the airship crew; no formal immunity or exact mechanism is stated 369.
• Effortlessly kills the awakened frozen demon and has also destroyed an entire demon army witnessed by Li Wei 524.

These incidents do not establish universal immunity to magic or mind control: she was previously affected by the House of Death’s memories and controlling soul threads 42 43 47 234.

Swordsmanship and Heavy Weapons

Katie later supplements her fists with a greatsword and weapons normally mounted on machinery 369 447 650.

• Uses a greatsword to wound a dragon’s hind leg and sever a toe after identifying its talons as a vulnerable target 369.
• Operates a flamethrower removed from a Knight Mech, carrying its enormous fuel tank with little apparent difficulty 447 448.
• Uses the flamethrower tube as a blunt weapon when the Plague Child survives the initial fire attack 448.
• Occupies the Night Raven Mecha’s fire-control cockpit during the Church headquarters expedition 524.
• Leaps from the cockpit and throws a shell into the angel-like creature’s damaged All-Seeing Eye, completing Li Wei’s attack 528.
• Cuts through goblins with a greatsword during the caravan rescue 650.
• With her enchanted greatsword, cuts a blue dragon’s wing and severs its tail 673.
• Uses the greatsword rather than her fists against spike-covered Crystal Monsters, cutting through their ranks 751.

Dragonmark

Katie bears an invisible Dragonmark recognized by the blue dragon as proof that she has slain one of its kin. The mark is described as the final release of a dying dragon’s draconic essence, detectable by Dragonkin but without an effect on other races 673.

Its recognition causes the blue dragon to abandon its initial contempt and treat Katie as a dangerous opponent. Katie identifies the earlier dragon as the creature whose remains are being studied at the Imperial Research Institute 673.

Social Access and Disguise

Her connections overcome barriers that Li Wei’s investigative skills cannot 16 17.

• Arranges entry to the private Glorious Club and admits both herself and Li Wei using a membership card 16 17.
• Mingles comfortably with the club’s women, discussing fashion and cosmetics 17.
• Uses a disguise while helping at the Pink Lady, preventing Lady Claytie from recognizing her during their club meeting 19.
• Draws information from Sanctuary’s adventurers through her approachable presentation as an enthusiastic noblewoman on her first adventure 653.
• Understands royal etiquette and the social consequences of failing to extend customary invitations 750.

Investigative Assistance

Katie is an enthusiastic but inexperienced assistant who contributes observation, note-taking, and familiarity with religious settings 20 38.

• Finds the pull ring that moves Lady Claytie’s bed and exposes a concealed staircase 20.
• Recognizes the underground altar’s layout as resembling a Holy Lord Church sanctum and explains the throne’s significance 20.
• Records the tavern patrons’ accounts of the House of Death, despite becoming exhausted by the volume of writing 38.
• Conducts inquiries separately from Li Wei during the preliminary investigation into Sophia Cront’s journey and returns with information 273.
• Records the locations of the three Holy Relics during the City of Eternal Night investigation 278.
• Identifies the auction painting depicting the sea, Deep Ones, and the enormous monster, helping Li Wei locate the source of the crisis 344.
• Notices that Li Wei’s movements avoid an invisible obstruction even though she cannot directly perceive the distorted reality 476.
• Continues accompanying interviews and searches, but misses the maid’s suspicious glances toward Gladys Caldwell’s flower until Li Wei and Sophia explain their significance 764.

Vulnerabilities

• The bat monster’s piercing cry leaves her dizzy, disoriented, and struggling to hear instructions 33.
• Small dolls can restrict her movement by clinging to her legs; Li Wei must shoot them free 45.
• The House of Death traps her in a doll’s memories, temporarily making her experience another woman’s life and impending murder 42 43.
• Scarlet soul threads later control her body without taking away her awareness or will 47 49.
• She cannot see the enormous controlling doll that Li Wei detects through Soul Sight 48.
• Her immense strength does not initially come with exceptional speed comparable to Ovelia’s; Li Wei explicitly distinguishes their respective strengths 96.
• Fear of ghosts can prevent her from participating in an investigation, as at the haunted Academy 281.
• Her strength does not make her invulnerable to weapons. During the confrontation with the Silver-armored Knights, she ignores their blades because she trusts Li Wei to intercept them, not because their attacks cannot hurt her 667.
• Illusions can misdirect her attacks, allowing the blue dragon to escape her strike 673.
• The Sun Temple girl’s flaming tentacles rapidly disintegrate Katie’s stone pillar, preventing her improvised weapon from breaking through their defenses 703.

Relationships

• Li Wei — Investigative partner whom she usually calls “Mr. Detective.” She protects him in close combat, while he supplies investigative direction and repeatedly rescues her from supernatural traps. Their reliance is mutual, though no romantic relationship is confirmed 10 16 42 45 48.

Story Role / Major Arcs

Courtesan Killer Investigation

Katie accompanies Li Wei to the Royal Academy of Medicine, where they question Edwards about Amelia’s death. She challenges Li Wei’s deceptive methods and initially trusts Doctor Dolittle’s reputation as a charitable physician 8.

After insisting on remaining involved until the killer is caught, she enters Dolittle’s hidden operating room with Li Wei and Lestrade. Her fighting ability becomes crucial: she protects Li Wei from the small creatures and holds back the larger monster. She is shocked when Li Wei identifies that monster as Amelia 9 10 11.

Katie disappears after the case because her family keeps her at home. When she returns, she refuses the reward money Li Wei saved for her and requests further investigative work instead 12 16.

Lady Claytie and the Underground Chapel

Katie secures access to the Glorious Club, where she and Li Wei encounter Lady Claytie using the name “Lady Durex.” After Claytie’s death, Katie joins the search of her Pink Lady office, finds a hidden safe, and later discovers the mechanism exposing the underground passage 17 19 20.

In the chamber below, she recognizes the resemblance to a Holy Lord Church sanctum. Unlike Li Wei, she reports no unusual dreams after visiting it 20 26.

Vampire Murders

Katie accompanies Li Wei to the police morgue after Edwards’s body disappears and knocks the reanimated attacker into a wall. Her household’s butler then arrives with armed support 24 25.

During the final ambush, she intercepts Maggie. When Maggie and Betty merge into a batlike monster, Katie throws fuel tanks at it despite the disorienting effects of its cry; Li Wei detonates the tanks with gunshots, killing the creature 32 33.

House of Death

Katie helps gather local accounts before joining the cross-departmental investigation. Inside the house, she is trapped in a doll’s memories as a mother whose husband murders their children and turns his knife on her. Li Wei destroys the attacking puppet and frees her 38 41 42 43.

She subsequently helps rescue Anthony and Henry, fights the doll swarms, and uses a bookcase to pin down armed puppet soldiers. The true controlling entity then forces her to attack Li Wei, though she remains conscious and warns him about her movements 43 44 45 47.

After Li Wei destroys the entity, Katie helps him to his feet and describes his seemingly inexplicable leap toward the ceiling, confirming that she could not see his target 48.

Animated Objects and the Secret Hunt

Katie continues serving as Li Wei’s principal close-combat defender against increasingly unusual enemies. During an encounter with animated furnishings, she smashes an attacking chair and breaks through a closed door. Afterward, Li Wei explicitly credits her protection as essential to surviving the investigation 75 76.

Cemetery Apparition and Prison Island

Katie brings Li Wei to Honor Cemetery to investigate the rumored Lady of Death. They encounter a disappearing woman and inspect Jim Rogers’s ambiguous memorial, which lacks a death date. The old butler and Lestrade connect the encounter to an unsolved mansion tragedy from more than fifty years earlier 187 188 189.

During the ensuing investigation, Li Wei warns Katie that the ghost’s request to end the haunting may be manipulative. Frightened by the possibilities, she chooses to sleep in his room rather than remain alone. In a later fight, she punches a monster through a granite wall 194 201.

She later recalls the Prison Island trip fondly, regretting that she did not fight the larger creature Li Wei encountered. The cemetery woman’s identity remains an unresolved question in her recollection 204.

Clock Tower and Monastery Expedition

Katie enthusiastically explores Li Wei’s renovated Clock Tower, especially its infinity pool, and asks whether she can stay there. Li Wei welcomes the idea provided she obtains permission. She later frequently visits the heated pool when he is away 204 258.

During the snowy expedition, she rolls an enormous snowball and hopes to hollow it into a snow house. At the monastery, she overpowers a winged ambusher that tears her favorite coat but leaves her visibly unharmed. Lavinia repairs the damage before the group takes shelter inside during a blizzard 210 212.

Nursing Home Sorcerer

At the nursing home, an apparently helpless old man lures Katie into a storeroom and attempts to incapacitate and control her. The spell fails. When he reveals tentacles, she breaks through a wall and calls Li Wei rather than trying to resolve the encounter alone 234 235.

Returning together, they find a hidden passage behind an iron cabinet, which Katie tears away. In the ritual chamber, Li Wei suppresses summoned Byakhee while Katie forces her way through, seizes the sorcerer’s tentacles, and binds him with them. Her intervention interrupts the ritual, allowing Li Wei to investigate and destroy the grimoire sustaining the sorcerer 235.

Twisted Picture-Book Creatures

Katie accompanies Li Wei and an old hunter through a mine populated by grotesque storybook-like creatures. She destroys a giant rabbit’s paw, kicks it away at Li Wei’s direction, and later kills a huge serpent by smashing its head into the ground. The defeated creatures disappear and leave drawings behind 248 249.

Her compassion leads her to comfort an enormous crying duck, only for it to reveal predatory intentions and attack. Li Wei’s investigation connects the drawings to Miss Dun’s unfinished picture-book project and the mysterious girl Alice 249.

City of Eternal Night and the Holy Relics

Katie joins the investigation into Sophia Cront’s journey and enters the cursed city with Li Wei. A ghost warns them that outsiders cannot leave and that dangers increase toward the inner city. Katie thanks him with a biscuit despite her fear 273 275.

The pair conserve ammunition by fighting hostile locals with Li Wei’s sword cane and Katie’s fists. Katie also provides a carefully prepared outdoor tea service, creating a quiet interlude before their meeting with Harold 276.

She records the three Holy Relic locations and eagerly supports the search, but refuses to enter the ghost-filled Academy. Li Wei sends her and Sophia Cront to wait elsewhere, where Katie promises to protect Sophia 278 281.

At the Church, she withstands a tentacled creature’s attempt to drag her away and instead uproots its true body. Holding it in place, she enables Li Wei and his silver-armored Doll to locate and destroy its core 287.

Auction Ship and the Sea-Monster Painting

Katie accompanies Li Wei to the vault where Princess Louise is trapped. Her strength tears through the heavy doors, while Louise asks whether she is happier with Li Wei than among the people of the palace 343 344.

When a colossal monster threatens the ship, Katie identifies the auction painting depicting it. Li Wei attacks the image, causing the monster and its associated manifestations to disappear. Although disappointed that she does not fight the monster directly, Katie is delighted when Li Wei explains that opening the vault quickly helped save everyone 344.

Household Companionship and the First Dragon Battle

Katie becomes a familiar presence around Alice, Sophia, Muse, and the household animals. She comforts the children, mediates disputes, and remains bored when Li Wei attends events without her. After missing the Cromwell investigation, she declares that she will accompany him everywhere 357 363 392.

Beneath the city, Katie and Li Wei discover a dragon sleeping among treasure. At his direction, she prepares the Descent Pod while he distracts it. They escape the pursuing dragon’s fire by jumping from the pod and gliding with his cloak 368.

In the subsequent battle, Li Wei draws the dragon’s attention while Katie attacks from behind with her greatsword. She wounds its hind leg and severs a toe, creating an opening for Li Wei’s attack on its head. Later, the blue dragon’s recognition of her Dragonmark confirms her participation in slaying a dragon 369 673.

Plague Investigation and the Church Eye

During the lake-bed temple expedition, Katie equips protective clothing and carries a Knight Mech flamethrower. She forces open the sealed entrance while Li Wei scouts ahead and examines the evidence of an earlier Church assault 447.

Against the Plague Child and corrupted knights, she supplies sustained fire and then strikes the surviving monster with the weapon’s tube. Oxygen depletion undermines their fire-based tactics, and she follows Li Wei’s retreat signal 448.

Later, when Elizabeth is trapped in a terrifying supernatural experience inside a Church, Katie throws a heavy pew at the All-Seeing Eye after Li Wei’s shot fails to destroy it. Smashing the Eye ends the red light affecting Elizabeth, and Li Wei asks Katie to watch over her 454.

Parallel-World Investigation

Katie travels with Li Wei through a parallel world whose military development favors biotechnology over steam machinery. She carries Baron Hanklis’s coffin, helps investigate the manor’s reality distortion, and worries about Fog City and the Empire’s fate 476.

After accompanying Li Wei’s meeting with George V and General Haig, she is dismayed that this world has a king rather than the familiar queen. Li Wei explains that parallel counterparts may have different identities and lives 479 480.

Katie helps free Annie by snapping prison bars, then tears apart another heavy iron door during the research investigation. Annie interprets her strength as possible Beastman engineering, but Li Wei rejects that explanation 483 486.

She listens to Annie’s explanation of Kront’s research and reacts with shock to Annie’s hostility toward the Empire. Katie admires the original medical goal of restoring lost limbs, contrasting with the military use of the technology 484.

Holy Maiden and the Church Headquarters

Katie reunites with Li Wei aboard the Glory Forward and observes Elizabeth’s confrontation with the Holy Maiden over divine authority and the Church’s alleged demonic connections 521.

After Katie effortlessly kills an awakened demon, the Holy Maiden identifies her as a Saint and questions the nature of her unusual abilities. Katie is delighted by the physical challenge of fighting demons and joins the planned investigation of the Church headquarters in the Night Raven Mecha’s fire-control cockpit 524.

During the aerial battle against the angel-like creature, Li Wei damages its central All-Seeing Eye and signals Katie to throw a shell. Her attack shatters the Eye, releases a golden light, and completes the sealed-soul rescue 528.

Sanctuary Adventures

With the Queen’s permission, Katie enters Sanctuary alongside Li Wei and the younger girls, eager to reenact the heroic adventure stories she loves 648 649.

At the Salty Dog Tavern, she stops two half-orc robbers, breaking one’s arm and shattering the other’s axe before Li Wei restrains her enthusiasm. She then joins Robert’s caravan-rescue mission, charging through the goblins with her greatsword 650.

Katie leads further combat against barbarians, goblins, kobolds, and Dragon Cultists. She also gathers information from adventurers, while the younger girls develop new abilities through repeated fighting. Li Wei observes that Katie herself does not acquire dream-taught spells in the same way 653 655 660.

Aria’s Rescue and the Silver-armored Knights

After adventurers mock her interest in the dragon hunt, Katie defeats the troublemakers and damages the tavern; Li Wei pays for the repairs. The group subsequently joins the expedition associated with Emily and the Arrow of Light 660.

During the rescue of Princess Aria, Katie launches the fortress assault prematurely and smashes through its enormous gate. In the hall, she confronts the transformed mage Butcher and accidentally kills him by punching him through a wall 663 664 665.

When Silver-armored Knights later attempt to seize the group, Katie charges while Li Wei deflects their blades with playing cards. Their coordinated response subdues the immediate threat, after which Li Wei exposes the captain’s lack of proper authorization 667.

Blue-Dragon Hunt

In the blue dragon’s lair, Katie receives magical enhancements with the other fighters and eagerly prepares to attack. The dragon recognizes her Dragonmark, identifies her as a dragonslayer, and becomes both furious and afraid 673.

Her enchanted greatsword cuts through its wing and later severs its tail. She further enrages it by explaining that its slain kin is being studied at the Imperial Research Institute. The wounded dragon uses illusions to evade her attack and escape upward, prompting Li Wei to alert Alice, Sophia, and Muse 673.

Sun Temple Tower and Unresolved Identity Clues

In Sanctuary, a wanderer identifies Katie as the Holy Maiden depicted in murals, claiming that her appearance and clothes match exactly. An old man instead calls her a witch and attempts to attack her before soldiers restrain him. The Beauty God detects a mixture of hatred and fear but cannot determine whether it concerns Katie personally or the Sun God Church’s Holy Maiden 685 686.

These reactions do not establish that Katie is the previously encountered Holy Maiden or resolve her true identity. Li Wei continues to rely on the Royal Family’s approval of her participation without demanding an explanation 686.

At the Sun Temple Tower, Katie uses a stone pillar against worm-filled guards and the sealed entrance. The girl within destroys the pillar with blue-green flaming tentacles, so Katie helps distract her while Li Wei maneuvers behind her 703.

During the enemy’s second phase, Katie continues following Li Wei’s coordinated instructions. He ultimately sends her to evacuate the High Priest and Beauty God before confronting the remaining divine manifestations with the mirror 704.

Underground Military Expedition

Katie supports the Second Field Company against Spider Monsters, driving through their ranks and knocking several into the air. After the Empire’s Dispel Team counters the monsters’ Darkness spell, she eagerly joins Li Wei’s search of nearby buildings 739.

In another engagement, she turns a minecart into a heavy improvised weapon, smashing underground monsters and carrying it above her like a shell as she advances 743.

She later uses her greatsword against spike-covered Crystal Monsters. In the Royal City study, she watches stone-preserved scenes of a prince leaving the Sanctuary, returning to kill his father, and eventually authorizing a ritual with Holy Lord Church representatives 751 754.

Gladys Caldwell’s Disappearance

Katie and Sophia accompany Li Wei to investigate sixteen-year-old Gladys Caldwell’s disappearance in Baldur’s Gate. During the interviews, Katie misses the maid’s suspicious attention to a withered sky tulip, and Li Wei and Sophia explain why the behavior matters 764.

When the investigation reaches a locked underground entrance, Katie prepares to force her way through, but the elven mage opens it quietly to avoid alerting anyone. Deeper in the labyrinth, Li Wei gives Katie the greatsword, and she advances toward the sounds of fighting with Sophia following nearby 766 767.
