William’s backstory:

William was the reason his entire family died, including himself.

When he was only a young boy, there was a war, and his race was being hidden away.
He wasn’t allowed to go outside, to speak, or to make himself known in any way.
However, he was curious as to what he was missing, and left anyways.
Of course he was captured, and forced to tell where his family was hiding.
There, he was forced to watch each of his family members, one by one, get slaughtered in front of his eyes.
He was only 7.
His mother, father, and two older brothers were gone.
And then it was his turn.

William was dead for around 100 years before he was brought back. He didn’t know why he was brought back, and believed he didn’t deserve it.
He was alone, he was guilty, he was an idiot.
He committed suicide multiple times, but he could never stay dead, so he stopped trying for a while.
He tried to continue on, but every step was killing him inside, because he knew he could never get them back.

"Why was I the one to come back??"
