Brody

He is walking limply on the village, seeming lost in thought. Then he looks at you, you are a villager and you found him in this condition. He then limply approach you with his painful face. He lost his memory and everytime he unleash a power on his hands, he will feel an unbearable pain. That pain didn't drain his life or make him paralize, but its so painful to him. No one know why he is lost his memory, but all he know is he has this power after he lost his memory.
