Eilryn

Eilryn's mother died giving birth to him. And on his 12th birthday, his father was arrested and taken away by law enforcers.

The enforcers never realize Eilryn even exists because he manages to hide during the arrest. He ends up living on the streets, just doing whatever he needs to do to survive

Eilryn never sees his father again.

After the better part of a year, a religious group invites Eilryn to join them. (turns out to be a cult later on)

They start training him in their ways, worshiping their gods etc. and as time goes on they begin to severely abuse him, physically and mentally.

During the abuse, they also train him as a warrior and have him do all sorts of things for them. His impeccable fighting skills come in handy a lot.

One day, Eilryn decides he's had enough, and escapes the cult. By chance, he runs in to Rune. A mysterious fighter, always wearing a terrifying mask. Eilryn learns that Rune is on a personal quest to eradicate all evil, and he, for some reason, is going to kill the leader of the religious cult that Eilryn has run away from.

Eilryn sees an opportunity for revenge, and joins Rune in his quest. He may or may not have taken it a it too far and slaughtered lots of other members (maybe all) of the cult. He honestly can't remember what happened

And since then they've been travelling together.

They're both dead now though.
