Saint Amaranth

Saint Amaranth was born in a totalitarian theocracy and was raised from childhood to be a vessel for the energies of the divine. She is forced to aid the crusades by ingesting a concoction known as "Seraph's Blood" that gives her potent healing magic at a horrible cost to her body and wellbeing. Driven by fear of God and self-hatred, she seeks martyrdom as an escape from her hellish existence. Her retainer that she was assigned is the sole source of any goodness in her life at all, but she forbids herself from getting close to them for fear of God's wrath.
