For five grueling years, the young Haydee is kept in a stone cell within the secret stronghold of the Zabaniya, a notorious order of assassins. The trainers subject her to excruciating physical and magical modifications, exploiting her Beowulf werewolf regeneration to carve runes onto her bones and force her into boiling blood baths to harden her fur. Rather than breaking, she learns to dissociate her mind from her body, becoming the lethal assassin known as Wraith, responsible for over a hundred silent kills. Her captivity reaches a sudden, violent climax when the joint forces of the Radiant Sun and the Holy Orders raid the stronghold. As the base crumbles under explosions, her handler Malik attempts to force the children to fight the paladins. Seizing her chance for freedom, Haydee catches Malik off guard, thrusting her psionic-clad hand straight through his back and chest, destroying his heart. The slave compulsion instantly triggers a horrific magical backlash, causing her body to smoke and corrode on the floor as she screams in agony, her regeneration desperately fighting the decay. She is saved by Captain Faylen Sarfina, a templar who mistakes this act of desperate survival for a heroic sacrifice. Sarfina calls in holy healers to break the remaining slave bonds and stabilize her, unaware that the quiet, white-furred girl she is rescuing is actually the legendary assassin they came to destroy. During her subsequent recovery in the tenth circle of Day City, Haydee is subjected to a truth-detecting magical field during her interrogation by Sarfina. She carefully navigates the questions, admitting to taking lives but framing the deaths as the inevitable cost of her survival, while subtly implying that Malik was the true Wraith. This clever manipulation solidifies her position as a victim rather than a threat, allowing her to move into Sarfina's luxurious mansion. However, this fragile peace is built entirely on a lie of her innocence, leaving a lingering tension that her true identity could be exposed at any moment.

Moving into Sarfina's mansion exposes Haydee to the silent hostility of the elven servants, who look down on her beastly features. To establish her independence and secure proper weapons, she visits the stubborn dwarven smith Fimul Stormgranite. Fimul refuses to craft weapons for anyone who cannot appreciate them, forcing Haydee to undergo a rigorous throwing test. Unerringly throwing a variety of unbalanced, mismatched daggers into the eyes and armor gaps of distant targets, Haydee showcases her terrifying assassin precision. She then secures Fimul's respect by utilizing her innate alchemical genius to refine his secret rune-ink, doubling the power of his enchantments. In return, Fimul crafts her a set of custom, self-returning throwing daggers made of holy darksteel. Following this success, Sarfina begins Haydee's official pre-training, focusing on swimming to build balanced muscle and stamina. Sarfina's training is physically demanding, but to Haydee, it feels like a vacation compared to the abuse of the Zabaniya. She forms a deep, sisterly bond with the templar captain, though she continues to hide her true psionic potential. To broaden her skills, Sarfina recruits Taeral, a legendary elven ranger from the Tuatha De Danann empire. Taeral takes Haydee to a mana-rich great forest, where she struggles with sensory overload from her ambient mana detection. Under his tutelage, she learns the tradecraft of a ranger, mastering tracking, foraging, and camouflage. She even solves her greatest weakness, learning to attune her aura to her surroundings to hide her demonic presence from elven senses. This rigorous training transforms her from a raw survivor into a highly versatile scout, but her rapid physical growth and the mysterious tremors in her hands signal that her dormant heritages are beginning to wake, threatening to disrupt her carefully constructed life.

A visit to the local branch of the Threads of Fate introduces Haydee to an ancient seer who reveals that she must complete her Ritual of Choosing before her sixteenth birthday to secure her future. Recognizing the urgency, Haydee conspires with her saurian tutor, Mazatl, to perform the ritual in secret during a massive festival when the temple of light is empty. After pouring her blood onto the altar to draw the attention of the gods, she drinks a holy liquid that pulls her consciousness into the misty domain of the Pantheon of Gods. There, she encounters the ancient deity of time and his bickering daughters, Lumen, the Goddess of Light, and Umbra, the Goddess of Darkness. Both goddesses claim Haydee due to her engineered angelic and demonic lineages. In an unprecedented compromise brokered by the time deity, both Lumen and Umbra bestow their blessings upon her, alongside a mysterious blessing from the time deity himself. This massive influx of divine energy triggers an immediate, agonizing transformation, forcing Haydee to seek refuge in Mazatl's soundproofed quarters. She sprouts a pitch-black wing of darkness, a shifting lavender wing of light, and a glowing halo, while her hair turns a striking lavender color. She must learn to shrink her wings and hide her halo to conceal her divine heritage from the templars, who would be horrified by her dual alignment. This transformation also unlocks her Class five psionic power, represented by five fluffy tails in her fox form. She begins to train with the dark blade, a gift from Umbra's blessing that seems to suck in the surrounding light, learning to coat it in psionic energy to bypass magical barriers. She realizes that her path will inevitably lead to a confrontation with the angels of Paradisia, who have lost their way and turned their holy light into a tool of genocide. Armed with her new powers, Haydee prepares to leave the safety of the templar mansion to seek a psionic teacher, haunted by the realization that her engineered body contains the blood of the very angels she despises.

Haydee travels to the tenth circle of south Day City to study under Moirai, a Class nine Meilin psion. Moirai subjects her to a grueling training regimen, launching constant mental attacks to force Haydee to build instinctive mental defenses. During her physical training, Haydee struggles with telekinesis because her highly refined, dense power constantly crushes the objects she tries to manipulate. She achieves a massive combat breakthrough when she realizes she can use her telekinesis to manipulate her own psionic constructs, creating invisible hands to handle delicate objects and launch exploding psionic blades. This new technique is put to the test when a stampede of crazed beasts and low-level undead threatens their sub-community. Haydee tracks the source to an underground temple, where she confronts a powerful greater lich. The lich's dampening aura drains her physical strength, and its protective vestments render her holy magic useless. Trapped and facing a barrage of lethal ice spells, Haydee uses her new invisible hands to bypass the lich's defenses and trap its robes with alchemical superglue, buying enough time for Moirai to arrive and obliterate the monster. However, their victory is short-lived. A massive planar rift opens in the north, drawing a stampede of elemental monsters toward the city and triggering a primal, uncontrollable hunger for power within Haydee's demonic blood. As the city erupts into panic, the guardians hold the line against the oncoming horde, while Haydee is forced to confront the dark reality of her heritage. The mysterious tremors in her hands return, accompanied by an intense, addictive urge to take lives and consume their essence. The approaching elemental rift promises a clash of titanic forces, and Haydee must decide whether to flee with the evacuees or embrace the violent, hungry beast waking within her soul.
