Background

Kal'tsit previously commanded a multinational coalition during its invasion of Kazdel. The invasion left her widely hated among the Sarkaz; Teresis beheaded her, though her immortality allowed her to return after death. The consequences of the war remain central to her guilt and to Kazdel's hostility toward her. 1 16 39 77

After awakening, she returned to Kazdel to investigate the altered landscape and the apparent weakening of the Originium Project. Crossing from barren Victoria into Huang Cao's territory, she discovered lush vegetation, purified water, and a golden tree more than six hundred meters tall that suppressed Originium-related power. 16 17 33

She initially infiltrated Eden in disguise, but Huang Cao's plant-based surveillance detected and repeatedly hindered her. Rather than flee, she applied to his teacher-recruitment program under a false identity, passed examinations in eight subjects, and was employed to teach them all. Huang Cao later gave her the alias “Kaitian Cat.” 16 17 18

Appearance

Kal'tsit is a green-haired Feline whose ears make her recognizable even when concealed. Her appearance is often hidden because many Sarkaz recognize her as the coalition commander who invaded Kazdel. 16 17

• Usually wears a hood, veil, mask, or cloak when travelling through Kazdel. 16 17 52
• Worked in Eden in a maid uniform; her attire became progressively less formal during her long service there. 18 123
• Has been described as possessing multiple tails, including nine tails at one point. 83 98
• Can assume unusual forms, including a Spine Dragon form and a “monster form.” 178 357

Personality

Kal'tsit is highly knowledgeable, composed, and calculating. Her long life has given her extensive historical and scientific knowledge, though she admits limits in economics and military strategy. She is observant enough to see through political manipulation, but her concern for Kazdel and Theresia repeatedly leaves her vulnerable to Huang Cao's schemes. 16 53 75 78

Despite her former role in the invasion of Kazdel, she develops a genuine attachment to the land and wants the Sarkaz to learn from their destruction. Theresia's offer of “a home” affects her deeply and becomes a turning point in her loyalty to Kazdel. 34 39 53

Her time in Eden gradually changes her priorities. The hundred-year maid contract relieves her of the burden of acting as Terra's perpetual crisis manager, while her feelings for Huang Cao grow from fascination and conflict into an openly affectionate partnership. 76 83 140 153

Abilities & Skills

Immortality and Revival

Kal'tsit can return after death, though revival is neither immediate nor painless in its consequences.

• Was beheaded by Teresis but later returned to Kazdel. 1 16
• Revival can require anywhere from several months to several years. 140
• Her planned public death was intended to absorb Sarkaz resentment and allow her to atone for the invasion of Kazdel. 140 141 176
• Presis intercepted her during her revival and brought her into a white world before Huang Cao retrieved her. 178 196

Knowledge and Education

Kal'tsit possesses broad expertise accumulated across tens of thousands of years.

• Passed Huang Cao's examinations in Sarkaz language, mathematics, Victorian, Terra history, physics, geography, chemistry, and Kazdel situation analysis. 17 18
• Served as Eden's teacher across all eight subjects. 18
• Spent six months rigorously educating Theresia before returning to Eden under her contract. 76
• Later tutored the artificial Caprini Herimath and Evignad, encouraging them to think independently. 154

Stealth and Infiltration

Kal'tsit is skilled at covert travel and information gathering, although Huang Cao's territory specifically countered her methods.

• Entered Eden disguised and concealed her face to avoid recognition. 16 17
• Used a special camera to record notices beneath the Golden Tree. 17
• Travelled through Kazdel and Victoria to gather intelligence on political and economic developments. 39 52 66
• Her stealth was ineffective against Huang Cao's roots and plant surveillance, which extended beyond the mountain border. 16 17

Transformative Forms

• Huang Cao witnessed her body-changing ability, comparing it to the Shapeshifter Collective's transformations. 78
• Activated a Spine Dragon form upon confronting Presis after her revival. 178
• Used her monster form to retaliate against the stone that injured her. 357

• Theresia — Close friend, student, and political ally. Theresia offers Kal'tsit a home in Kazdel, while Kal'tsit teaches, advises, and repeatedly sacrifices for her future. 53 76 86 170

Story Role / Major Arcs

Return to Kazdel and Eden Recruitment

Kal'tsit returns to investigate Eden's transformation of Kazdel's environment and the apparent decline of Originium. After failing to evade Huang Cao's surveillance, she joins his territory as a teacher under a false identity. 16 17 18

Theresia's Adviser

After leaving Eden, Kal'tsit opens a low-cost tavern in Kazdel and meets Theresia. Moved by Theresia's offer of a home, she becomes her confidante, adviser, and teacher while concealing Huang Cao's true wealth and influence. 52 53 75 76

Hundred-Year Maid Contract

Seeking investment for Kazdel, Kal'tsit bargains with Huang Cao and accepts one hundred years of service in exchange for factory construction and a guaranteed annual income for Theresia's government. She returns to Eden after training Theresia for six months. 73 75 76

Kazdel's Economic Dependence

Kal'tsit recognizes that Kazdel's visible prosperity depends heavily on Huang Cao's economic power. She investigates deaths connected to the fertilizer plant, worries about Theresia's industrial plans, and struggles to protect Kazdel without exposing Huang Cao's larger agenda. 85 86 90 92

Utopia and the Fall of Kazdel

Huang Cao reveals Utopia, his underground mobile city, and asks Kal'tsit to pressure Theresia into developing Kazdel's own mobile city. As Utopia moves against Kazdel, propaganda turns public hatred toward Kal'tsit; she ultimately tells Theresia that they had lost more than a century earlier. 124 162 170

Atonement and Return

Kal'tsit agrees to a plan to die publicly and absorb the Sarkaz people's anger over the invasion. Her death reduces ethnic tension and consolidates Huang Cao's authority, but Presis intercepts her revival before Huang Cao brings her home. 140 141 176 178 196

Rhodes Island

After her maid title is shed, Kal'tsit works intensively on Utopia's development and helps prepare Rhodes Island for launch. She later becomes the highest authority of Rhodes Island's medical department and leads its psychological counseling work. 329 360 396 422

Trivia

• Kal'tsit deliberately scored only upper-middle marks in several of Huang Cao's examinations, apparently to avoid being overworked; Huang Cao assigned her all eight subjects anyway. 18
• She kept the price of drinks at her Kazdel tavern only slightly above cost. 51 85
• Her historical reputation is so poor in Kazdel that education materials openly record her role in the multinational invasion. 121
• Huang Cao's territory calls her “Kaitian Cat,” a name she associates with a woman from her past. 18
