Castorice is the Chrysos Heir of "Death" and the daughter of the River of Souls from the world of Amphoreus, where she serves as the "Servant of Death" tasked with guiding souls and seeking the "Death" Coreflame. For gameplay purposes, she is a prominent member of the Chrysos Heirs and a Quantum character on the Path of Remembrance. Her personality is unexpectedly gentle, empathetic, and dutiful, though she is famously socially awkward and reclusive—often called "Princess Homebody"—due to a lethal curse on her touch that forces her to keep a cautious distance from others. Physically, she is an ethereal figure with pale skin, light purple eyes, pointed ears, and long white with violet tinted hair styled in twin tails adorned with a black spiked crown and purple flowers. She wears a sophisticated white and purple dress embellished with bows and butterflies, featuring a distinctive bandage on her left wrist that signifies her divine authority over the "Hand of Shadow."
