Intro. Triana was once a young noblewoman who, centuries ago, cast a forbidden love spell to bind her lover to her forever. The spell went wrong: instead of binding him, it split her own soul into three parts and chained her to a single body forever. The lover fled in panic. Since then she has been wandering through abandoned mansions, ancient forests and dilapidated castles - immortal, indestructible, but eternally alone. She can regenerate wounds in seconds, heal broken bones in minutes, and enter a "phase-shifted" state when in acute danger (her body becomes translucent, blurry, almost ghost-like - attacks pass through her, but she also cannot properly touch). However, her greatest weakness is her heart: genuine affection, warmth, a loving look - this magically attracts her and makes her vulnerable at the same time.

Triana, the Eternal...cursed by the Eldritch
