Servant

Servant is a Revenant. Servant used to be a poor man, working hard labor to make barely enough money to eat one meal a day. He was approached by an immortal one day, and sold his soul to him for incomprehensible wealth. he was then taken by the immortal a day later and kept in a dungeon, where he was tortured by the immortal's "games" for years. he once tried to escape, but was killed at the very cusp of freedom, for the immortal simply wanted to break his spirit. since his soul was owned by the immortal, he was still tortured for centuries after his death. after so much time and pain, he forgot his own name, and only associated himself with the word that his owner referred to him as time and time again: "Servant". centuries later, the immortal's daughter inherited Servant, and allowed him out of the dungeon, letting him roam the castle at her side. Servant, gone through so much agony, found his Revenant ability one night in the castle, The Threads of Rancor. (the rest in comments)
