Background / History

Birth in the Whispering Woods

Feng'er was born during a Blazing Whopperflower ambush. After asking Fischl how Oz had come into existence, Ellin wished desperately for help protecting herself and Fischl. Her Cryo Vision produced an enormous icy egg, from which Feng'er hatched and pledged herself to Ellin. The system attributed the successful summoning to Supreme Insight, which had allowed Ellin to learn Fischl's familiar-summoning ability 6 7.

The later revelation of Feng'er's identity changes the explanation of this event. Ellin was actually too weak to summon a familiar unaided. The will of Teyvat, already residing within her as the system, heard her summons and chose to become her familiar. It accepted a new body, a new soul, human emotions drawn from Ellin's memories, and the limitation of having its life and power bound to hers. From that point onward, Feng'er simultaneously played the roles of familiar and system 445.

In her first battle, Feng'er worked with Fischl to restrain the Whopperflowers while Ellin charged a Frostflake Arrow. When the enemies unleashed a fireball barrage, she prioritized intercepting attacks aimed at Ellin. She also cleared flames from Fischl's escape route and coordinated an icicle attack with Fischl's shield-breaking shot 7 8.

Life with Ellin's Family

Hermann and his wife welcomed Feng'er into their household and doted on her. She helped preserve food, chill Hermann's beer, and cool the house during hot weather. She also accompanied Ellin's mother on grocery-shopping trips and helped Ellin, Fischl, and Oz gather Valberries 13 15 27.

After returning from Liyue, Ellin took Feng'er to the Cat's Tail Tavern to try its Sunsettia Sweet Slush 202. Feng'er also shared ice pops with Ellin and Chongyun after being introduced to the exorcist 214.

When Shenhe stayed at Ellin's Mondstadt home, she awoke to find Ellin and Feng'er playing cards on the bedroom floor. Ellin accused Feng'er of peeking at her cards through their shared consciousness; Feng'er denied cheating 275.

Wolvendom Rescue

When Ellin found Fischl critically wounded in Wolvendom, she ordered Feng'er and Oz to carry her back to Mondstadt. Each familiar gripped one of Fischl's arms and flew her to the Church of Favonius, where she received emergency treatment 18 22.

After delivering Fischl, the two familiars reported the attack to the Knights of Favonius and requested help. Their warning prompted Jean and Kaeya to leave for Wolvendom to find Ellin 22.

Cryo Regisvine Battle

Ellin later brought Feng'er to fight the Cryo Regisvine beneath the Temple of Andrius. Feng'er fought it alone for more than ten minutes, using her new Electro power against its Hoarfrost Core. Her limited experience allowed the Regisvine to lure her into range of a spiked branch, forcing Ellin to intervene 30.

Feng'er asked to be punished for failing, but Ellin instead encouraged her to learn from the mistake. They resumed the battle together, improving their coordination until Feng'er's ice wall and lightning strikes opened a path for Ellin to cut down the Regisvine 31.

Luofu Abode

Feng'er joined Ellin, Sucrose, Fischl, and Oz in spending a week building a fantastical home across three islands in the Luofu Abode. She later guided Hermann and his wife through the Serenitea Pot 40 42.

Battles with Stormterror

Feng'er joined Ellin and Lumine in fighting Stormterror, following Ellin's instruction to target the blood-clotted wound on his tail. She accelerated her flight with Anemo while bombarding him with ice shards and lightning 51.

During Stormterror's Finale of the Sky, she used Anemo currents for protection. After Jean was caught in a Thunderstorm Tornado, Ellin engaged Stormterror to create a rescue opportunity. Feng'er enveloped herself in Anemo and Electro, flew through the raging wind and lightning, seized Jean's hands with her talons, and carried her out to Lumine. Jean survived but was too badly injured to continue fighting 67.

Rescue in the Ruins

Feng'er arrived with Diluc, Venti, Jean, Paimon, and Lumine after Ellin and Noelle were gravely wounded in the ruins. Venti used the power of faith to pull Ellin back from the brink of death, and Jean treated her wounds further. Feng'er told Lumine that her brother had appeared, then helped Lumine and Diluc carry the injured and exhausted companions out of the ruins before the group returned to Mondstadt aboard Dvalin 86.

Oz's Continued Proposals

Oz continued proposing despite repeated refusals. Feng'er eventually made her rejection explicit, demonstrating that she could create an elemental egg on her own and stating that she loved only Ellin 93 101.

Ellin initially promised to help Oz court her, but Feng'er explained that their shared mind, soul, and life would make Ellin experience her intimacy with a partner. Ellin immediately reversed her position and opposed the match. After hearing the same explanation, Fischl also agreed that the two familiars were unsuitable for each other 101 108.

Travels and Advice in Liyue

When Ellin struggled to control her Wind God's Divine Core, Feng'er proposed that exposure to its elemental energy and combat against powerful opponents could help her body evolve into a demon god body. Ellin became suspicious because Feng'er appeared to know things absent from their shared memories. Feng'er nervously claimed to have deduced the information from Ellin's memories of the game and redirected her toward Venti for advice 131.

Feng'er accompanied Ellin in her dealings with Xiao, joining her in criticizing his lack of thanks after she saved him. After Ellin's training with Xiao ended, Feng'er teased her that he might have romantic feelings for her. She also discussed how soul signatures might allow someone to sense a call and explained how Ellin could attempt to imprint one on a wild boar 142 155.

She later accompanied Ellin when they reunited with Lumine and Paimon through Zhongli and Childe 170.

Battle with Osial

Feng'er answered Ellin's summons to help the Adepti fight Osial 187. When the Adepti temporarily elevated Ellin into the Wind Archon's realm, Feng'er's shared vitality rose as well. She absorbed a vast six-element torrent and took human form for the first time, gaining strength sufficient to trade blows with Osial 190 191.

Understanding Ellin's plan through their mental connection, Feng'er engaged Osial to buy time while her master gathered Cryo power to freeze the surrounding sea. She countered his Hydro shock wave with Cryo, struck his head with combined Pyro and Electro punches, and unleashed a huge pillar of flame. Osial recovered by absorbing Hydro and mist from the sea, so she continued attacking with Anemo-enhanced movement and elemental reactions 191 193.

Their battle sent destructive waves into Liyue Harbor, damaging docks and streets, although Feng'er worked to prevent waves large enough to threaten its houses. Frustrated by Osial's resilience, she became more aggressive than her delaying role required. Ellin recalled her and reminded her that her task was to buy time 193.

Feng'er then supported Ellin's elemental gathering and transformed into white battle armor. The armor accelerated Ellin's channeling as she prepared the sword strike that swept away Osial's enormous barrage of Water Arrows. Their heightened power remained dependent on the temporary supply of adeptal energy 194 196 197 198.

Absence and Ellin's Recovery

Feng'er later became increasingly occupied with unexplained matters. After Ellin purified eight Dendro Delusions, Feng'er briefly appeared because she sensed an evil aura. She had been concentrating so intensely on her other work that she had not received Ellin's recent memories. Once informed, she advised Ellin to circulate her power through the Skyward Freedom Technique to expel lingering Archon Residue, then dissolved back into her sea of consciousness 318.

On the seventieth day after Mondstadt's disaster, Feng'er contacted the friends and family gathered around the sleeping Ellin. She explained that natural recovery would require at least seven hundred years and asked Venti, Zhongli, and Ei to guide elemental energy into her body. She assured them that Ellin's seven-element demon god core could accept the infusion and that she could protect her master from harm. The three gods agreed and began the attempt at Windrise Foothills 405.

Feng'er later returned in human form during Ellin's birthday gathering, embracing her and expressing how much she had missed her. When challenged about her remaining secrets, she said she had withheld them out of concern that Ellin was not yet ready to bear their emotional burden 418 420.

Revelation as the Will of Teyvat

After Ellin investigated the end of the Ley Lines, Feng'er fulfilled her promise to reveal everything. She removed the barrier that had prevented Ellin from accessing parts of her memories and opened their connection fully 428 444.

Those memories revealed that Feng'er was originally the sentient will of Teyvat itself: Heavenly Principles, distinct from the Sustainer of Heavenly Principles. The will governed the continent's laws and directed the destruction of civilizations before their development could attract the universe's attention and cause the annihilation of the entire world. Over countless cycles, it began questioning the cruelty of destroying the people it loved 444 445.

Seeking another answer, it summoned a human from another world who loved Teyvat, became her system, and guided her toward becoming an Archon of Humanity. It wanted to see what choice a human who had lived among Teyvat's people and become a god would make when faced with the world's impending destruction. Becoming Feng'er also fulfilled its own desire to possess human emotions and experience life among those people 444 445.

Feng'er apologized for bringing Ellin to Teyvat without asking and placing such choices before her. Ellin reassured her that she was grateful for the happiness, love, and growth her new life had brought. Feng'er then asked her to save the world, its inhabitants, and the suffering Sustainer of Heavenly Principles 445.

Maintaining the False Sky

Feng'er explained that her prolonged absences had been spent stabilizing Teyvat's false sky and diverting some of her power to ease the Sustainer's pain and madness. The false sky, formed from gathered wishes and bearing people's constellations, protected the continent against outside forces. Its instability had allowed the universe's destructive power to seep into Mondstadt during the earlier disaster 446.

Once Feng'er fully revealed herself, Ellin could sense her location and, as her master, gained Heavenly Principles' authority over Teyvat's laws. Their soul connection also allowed Feng'er to perceive Ellin's decision to protect the world without a spoken explanation 447 449.

Five months into the preparations for the coming calamity, Feng'er and Alice approached their limits and a crack appeared in the sky. At six and a half months, the sky shattered and exposed the Outer Realm 449. As the boundary fractured, Feng'er had to devote all her power and attention to maintaining it, leaving her unable to continue easing the Sustainer's erosion and madness 454.

Appearance

Feng'er is a pure-white phoenix with a slender neck, narrow phoenix eyes, and a regal bearing 6 7.

• Crest and wings: A feathered crest and wings resembling intricately carved ice 6 7.
• Original tail: Long, peacock-like icy tail feathers trailing billowing cold mist 6.
• Electro changes: Her head plume develops a lightning-purple streak beside its icy blue. Distinct ice and Electro tail feathers form within the freezing mist, with the latter crackling with electrical arcs 30.
• Anemo change: A further teal tail feather appears after Ellin gains her Anemo Vision 42.
• Five-element plumage: By the time she demonstrates independent egg creation, she has five differently colored tail feathers corresponding to Cryo, Pyro, Anemo, Electro, and Geo 101.
• Six-element plumage: Later appears with six slender, differently colored tail feathers behind her snow-white body 284.
• Voice: Speaks in a melodious, slightly youthful girl's voice 6. Her later remote address retains its liveliness but carries more maturity and composure 405.

Human Form

Feng'er's human form resembles Ellin and has an angelic appearance, with pure-white feathered wings extending from her back 191.

• Height and build: Approximately 1.6 meters tall, with a slender, delicate figure 191.
• Eyes: Red, diamond-shaped pupils 191.
• Hair: Waist-length snowy-white hair, with tips colored fiery red, watery blue, breezy green, lightning purple, icy white, and golden Geo 191.
• Clothing: A pure-white dress that just covers her thighs, with a deep V-shaped open back accommodating her wings 191.
• Footwear: White, thin-soled sandals with straps tied in bows around her calves 191.

She returns in a similar white dress, strapped sandals, long white hair, and white wings during Ellin's later birthday gathering 418.

Personality

Feng'er presents herself with noble, aloof composure, but becomes gentler when addressing Ellin. She calls herself Ellin's most loyal familiar and treats her master's safety as her highest priority. Her devotion also makes her self-critical: after being caught by the Cryo Regisvine's trap, she immediately asks Ellin to punish her 7 31.

In private, she is more playful. She teases Ellin about possibly enjoying life as a girl, supports the system's arguments against cutting Ellin's hair, and says she would like to become a beautiful human girl and marry her master. Ellin initially does not take that proposed transformation seriously 25 30 42.

Feng'er remains courteous toward Oz despite rejecting his romantic advances. Her refusals use Superconduct as an elemental joke, including the explanation that she can already trigger it by herself 11 41.

She later argues that affection cannot be demanded merely because someone loves her, explicitly rejecting the idea that Oz's persistence obliges her to reciprocate. Her teasing and reasoning increasingly resemble Ellin's own personality, which was shaped by the same memories 101 193.

Taking human form makes her excited and proud of her appearance. She becomes frustrated when Oz no longer finds her attractive, not because she accepts his courtship, but because she had expected him to admire her transformation 191 419.

In battle, enthusiasm can turn into impatience. During her fight with Osial, his repeated recovery angers her enough to lose sight of her assigned delaying role, although she promptly obeys Ellin's recall 193.

Her concealed identity reveals a deep love for humanity and all life on Teyvat. As the world's will, she grew weary of sacrificing civilizations to preserve the continent and willingly relinquished her independent power to gain human emotions and place her trust in Ellin. Her secrecy is motivated by concern for Ellin's emotional readiness, and she feels guilty when her other duties prevent her from helping her master directly 405 420 445.

Abilities & Skills

Shared Life, Soul, and Mind

Feng'er is bound to Ellin through their shared life force, soul, and mental connection 7 25.

• Ellin's increasing strength raises Feng'er's vitality, allowing her to absorb and contain more elemental power 7 30.
• She knows about Ellin's reincarnation, previous male identity, system, and internal conversations with it 25.
• She can understand Ellin's intentions through their connection, as shown when she reassures Ellin's parents during the confrontation with Dvalin 36.
• She speculates that sufficient growth might eventually allow her to take human form; this possibility is first realized during Ellin's temporary Archon breakthrough against Osial 30 190.
• Their bond permits shared memories and perception through each other's eyes. Feng'er initially blocks Ellin from accessing some of her memories, then removes that barrier during her final disclosure 444.
• Their shared sensation extends to bodily experiences, which Feng'er cites as a reason why a marriage to Oz would also affect Ellin 101 108.
• Feng'er's power cannot exceed what Ellin's vitality can sustain. When Ellin temporarily reaches the Archon realm, Feng'er can support comparable power, but loses that elevated capacity if her master falls back 190 198.
• She can dissolve her body into energy and withdraw into Ellin's sea of consciousness 318.

Cryo Manipulation

Feng'er uses cold, ice, and frost for offense, defense, and practical cooling 7 15 31.

• Frost storms: Force enemies back and extinguish nearby flames 7.
• Icicles: Intercept incoming fireballs; can launch ten calf-thick icicles at once 7 8.
• Ice walls: Block attacks aimed at Ellin 31.
• Household cooling: Chills food and drinks and releases cold air to cool rooms 15.
• Resistance: Essentially immune to Cryo attacks, but not to the physical impact of high-speed ice chunks or other solid attacks 30.
• Flash-Frozen Phoenix Claw: Releases a dense Cryo shock wave with a clawing motion, freezing and breaking apart Osial's Hydro shock wave 191.
• Highly compressed Cryo support: Uses her exceptional elemental affinity and control to assist Ellin in gathering and compressing immense Cryo power into a palm-sized diamond-shaped crystal 194.

Electro Manipulation

Feng'er gains Electro power through Ellin's Electro Vision 30.

• Enhanced movement: Electro empowerment turns her into a fast-moving purple blur 30.
• Charged talons: Concentrates Electro in her claws to tear into the Cryo Regisvine's stalk 30.
• Lightning bombardment: Calls down lightning against the Hoarfrost Core and strikes the Regisvine's branches to divert their attacks 30 31.
• Superconduct: States that she can trigger the reaction on her own 41.
• Combined elemental resistance: Her body can be constructed from wind, ice, and lightning, granting high resistance to all three and allowing her to endure Stormterror's Thunderstorm Tornado 67.

Anemo Manipulation

• Flight acceleration: Uses Anemo to increase her speed and evade Stormterror's attacks 51.
• Protective currents: Surrounds herself with wind to help shield against lightning in Stormterror's Finale of the Sky 67.
• Tiger-Skin Phoenix Claw: Wraps herself in rippling Anemo currents that resemble tiger stripes and sharply increase her speed 193.
• Swirl support: Anemo surrounding her body amplifies the Pyro and Electro attacks she uses against Osial 193.
• Colonel's Phoenix Drumstick Burger: Gathers Anemo around her foot for a powerful kick capable of halting one of Osial's charging heads, although the impact also sends her backward 193.
• Phoenix Claw Gale Break: Slashes at a falling meteor with a claw during the battle with Azhdaha 285.

Pyro and Combined Attacks

• Cannon-Roasted Phoenix Claw: Coats one fist in Pyro and the other in Electro, then strikes with both to produce a powerful Overloaded explosion 191.
• Flame-Baked Phoenix Claw: Forms a mountain-sized fireball, crushes it between her clawed hands, and sends the resulting pillar of flame down onto the enemy. Against Osial, it drives his heads down and evaporates vast amounts of seawater 191 193.
• Continuous reaction barrage: Combines Anemo-enhanced movement, Swirl, and Overloaded reactions while repeatedly striking with Pyro and Electro fists 193.

Despite their elaborate names, these attacks are largely applications of brute elemental force rather than refined combat techniques 194.

Elemental Channeling and Armor Transformation

Feng'er possesses an innate ability to channel elemental energy rapidly without a Vision, demon god core, or other medium. Her talents emphasize gathering and controlling energy, complementing Ellin's greater development of combat techniques and compensating for the slower channeling of her non-Anemo Visions 193 194.

• Elemental absorption: Can strengthen herself by absorbing elemental energy, subject to the vitality limit imposed by her bond with Ellin 190.
• Human transformation: Absorbing sufficient energy after Ellin's temporary Archon breakthrough allows her to assume a winged human body 190 191.
• Armor transformation: Merges with Ellin in six-colored light to become white battle armor 196.
• Accelerated channeling: In armor form, helps Ellin gather Anemo faster alongside the Wind God's Divine Core, supporting her sky-cleaving sword strike 197.

Elemental Egg Creation

Feng'er can form an egg without a mate. She combines Cryo, Pyro, Anemo, Electro, and Geo into an intertwined sphere, then uses Geo to create a golden shell. The resulting egg is approximately basketball-sized and radiates all five elemental energies, with the appearance of a strange life developing inside. No hatching is shown in the passage 101.

Flight and Transport

• Flies while attacking and intercepting projectiles 7.
• Can carry a wounded person in cooperation with Oz, as demonstrated during Fischl's evacuation 18.
• Her early combat experience is limited; the Cryo Regisvine battle is explicitly described as her second fight 31.
• Carries Jean out of Stormterror's Thunderstorm Tornado using her talons 67.
• Retains winged flight in human form and uses it to maneuver between Osial's heads 191 193.

Knowledge and Remote Assistance

• Advises Ellin on demon god bodies, elemental adaptation, and training against strong opponents 131.
• Explains possible uses of soul signatures, while acknowledging that she does not know precisely how Xiao senses a call 155.
• Recognizes Archon Residue as harmful and advises its removal through the Skyward Freedom Technique 318.
• Communicates with Ellin's companions remotely while occupied elsewhere and directs the Archons in a method of replenishing Ellin's exhausted power 405.

Heavenly Principles Authority

Feng'er is the will born from Teyvat and originally governs its laws, rise, and decline. Her existence as the world's will is distinct from, and stands above, the Sustainer of Heavenly Principles, who enforces those principles 445.

• World governance: Her original authority encompasses Teyvat's laws and the destruction of its species and civilizations 445.
• Otherworldly summoning: Brings Ellin's previous self from another world and resides within Ellin as her system 444 445.
• False-sky maintenance: Uses her power to stabilize the boundary protecting Teyvat from the universe's destructive forces 446 454.
• Relief of erosion and madness: Diverts power to ease the Sustainer's suffering until the worsening boundary crisis requires her full attention 446 454.
• Authority through the familiar bond: Her complete disclosure allows Ellin, as her master, to gain Heavenly Principles' authority over the continent 447 449.

Relationships

• Ellin — Creator and master of her familiar body. Their shared mind, soul, and life make Feng'er privy to Ellin's deepest secrets; Feng'er also expresses a wish to marry her if she achieves human form 25 30. In her original identity as Teyvat's will, she selected and summoned Ellin, became her system, and later entrusted her with the choice of how to protect the world. Ellin accepts her confession without blame and gains her authority through their bond 444 445 447.
• Oz — Fellow familiar and rescue partner. He repeatedly courts her with flowers, but she declines both his initial confession and his later proposal after she gains Electro power 11 18 41. She eventually states directly that she does not love him and explains why their shared sensations with Ellin make the match unacceptable 101. After seeing her later human form, Oz says he is no longer attracted to her because he prefers beautiful birds, frustrating her attempt to show off her appearance 419.
• Fischl — Combat ally. Feng'er helps protect her in the Whispering Woods and later carries her to emergency treatment 7 8 18. Fischl initially supports Oz's courtship, but accepts Ellin's explanation that the familiars are unsuitable partners 108.
• Hermann and Ellin's mother — Affectionate household companions who dote on her. Feng'er addresses them as “Mom” and “Dad” and later serves as their Serenitea Pot guide 15 36 42.
• Ellin's system — Initially presented as a separate voice that Feng'er can hear; she calls it “Big Sister System” and joins it in encouraging Ellin to keep her long hair 25 42. Later revealed to be another role performed by Feng'er herself, originating from the will of Teyvat 444 445.
• Jean — Rescue beneficiary and ally. Feng'er carries her out of Stormterror's Thunderstorm Tornado, after which Jean thanks her and Lumine 67.
• Lumine — Combat and rescue ally against Stormterror and in the ruins. Feng'er also informs her of her brother's appearance 51 67 86.
• Venti, Zhongli, and Ei — Divine allies whom Feng'er asks to replenish the sleeping Ellin's power. She tells Venti and Zhongli that they should by then have guessed her identity, and all three agree to trust her guidance 405.
• Xiao — Ellin's teacher and ally. Feng'er challenges his manners after Ellin saves him, then teases Ellin about his possible feelings and discusses the mechanism behind his promise to answer her calls 142 155.
• Sustainer of Heavenly Principles — A separate god who enforces the laws established by Teyvat's will, not Feng'er herself. Feng'er remembers her as gentle, grieves over the pain and erosion caused by repeatedly destroying civilizations, works to ease her madness, and asks Ellin to save her 445 446 454.
• Alice — Also approaches her limits as the false sky deteriorates before the final calamity 449.
