Short Summary

Alchemised follows Helena Marino, a vivimancer and later animancer, who erases her own memories to protect her lover Kaine Ferron, the High Reeve. Imprisoned after the fall of the Resistance, Helena endures stasis, forced pregnancy, and psychological torment at the hands of the Undying, a regime led by the necromancer Morrough. Her hidden memories contain the key to defeating Morrough, and she must navigate manipulation, sacrifice, and the cost of love. With Kaine’s help, she escapes and gives birth to their daughter Enid. The war ends when her friend Lila Bayard kills Morrough. Helena and Kaine find peace on a remote island, raising their child while grappling with their past.

Full Summary

The story begins with Helena Marino waking from stasis in a necromancer warehouse, disoriented and shackled with lumithium manacles that suppress her alchemical resonance. She has been a prisoner for nineteen months. Her interrogator, Vivimancer Irmgard Stroud, discovers that Helena’s brain contains intricate transmutational barriers—evidence of deliberate memory erasure. Helena is taken to the Alchemy Tower, now called Central, where she is examined by the High Necromancer Morrough. He orders a gradual soul transference method to recover her hidden memories, assigning the High Reeve, Kaine Ferron, to manage it.

Helena is transported to Ferron’s estate, Spirefell. There, Ferron performs a mental examination, probing her mind. She recalls her academic rivalry with Kaine and her deep bond with Luc Holdfast, the former Principate. As the transference sessions continue, Helena suffers seizures and brain fevers. She learns that the war ended fourteen months earlier and that the Resistance was crushed. Stroud reveals a repopulation program—a forced breeding scheme for alchemists. Helena discovers she was sterilised and bears new scars from torture.

Through flashbacks, we learn the backstory: Four years prior, Helena was a healer for the Eternal Flame Resistance. To gain Kaine’s intelligence, she agreed to become his liaison, using vivimancy to emotionally enthrall him. As the war escalated, Helena grew close to Kaine, even using the Stone of the Heavens—a relic containing trapped souls—to save his life. She resisted orders to kill him, choosing to protect him instead. The Resistance began to fall apart as Morrough’s manipulation became clear.

Back in the present, Stroud reverses Helena’s sterilisation and forces her into the breeding program. Ferron is designated the sire. After initial horror, Helena becomes pregnant. The pregnancy triggers her suppressed memories to resurface. She recalls the war’s brutality—the loss of her friend Lila, the betrayal of Crowther, and her own role as an animancer who could rip reanimation energy from necrothralls.

Helena learns that Morrough created the Undying by binding their souls to pieces of his own bone. She and Kaine plan to escape, but Morrough’s power is immense. At a public execution, Morrough reanimates Luc’s corpse, and Helena is forced to watch. To protect Kaine from future interrogation, she erases all memories of the past two years using her resonance, becoming a blank.

Months later, Helena wakes from a coma with fragmented memories. Kaine has been searching for her, faking Lila’s death to keep her safe. He reveals that his cruelty was a performance for Morrough. Their baby Enid is born. The family flees to a remote island where they live in peace. Lila Bayard, now a Paladin, returns to Paladia and kills Morrough using a bomb designed by Helena and combat training from Kaine.

Years later, Helena and Kaine live quietly, raising Enid. Kaine secretly murders Stroud, the doctor who tormented Helena. As Enid grows, she leaves to study alchemy in Paladia. Helena and Kaine are finally alone, contemplating their future together, haunted by the past but grateful for their survival.
