Revenant

Revenant once was a man who struggled every day to survive in the underworld. He later decides to learn how to fight and become an assassin. He perfected his skills and became a very known assassin. Nobody even thought about betraying him, because he would kill anyone who was brave enough to do so.

Eventually he grew old and his strength started to fade. He then fights a young man with a golden eye and is killed by that man. Before he dies he remembers killing an old man with the same eye. He believes that this young man and that old person are the same.

Years later his killer, Zasalamel, returns to his body and resurrects him. Revenant is now a loyal servant of Zasalamel and helps him to achieve his goal.
