Castorice

Castorice is a Chrysos Heir from Aidonia in Honkai: Star Rail and the bearer searching for the Coreflame of Death in the Amphoreus storyline. Raised close to death and the River of Souls, she travels under a destiny that links her life, sacrifice, and the fate of the death-associated Titan Pollux.

Castorice's identity and role in Honkai: Star Rail

Gentle, solemn, compassionate, and accustomed to isolation, Castorice treats death with tenderness rather than fear while struggling with the expectation that she must be sacrificed. She follows the Path of Remembrance, deals Quantum damage through team HP changes, and summons the memosprite Netherwing to attack, protect allies, and manipulate the boundary between death and renewal.

Castorice's role across the original work and adaptations

The Trailblazer and other Chrysos Heirs become her companions, while Pollux, Aidonia, and her adoptive past define the emotional conflict between personal life and inherited duty.
