Makvor was born in an orc settlement to a human mother, who was captured in some raid or another. From very early childhood, he was subjected to all manner of physical and emotional abuse. He was apprenticed to the tribe's shaman, who not only regularly beat him into submission, but looked the other way when the full-blooded children did the same. It wasn't long before he learned think quickly on his feet, and he was eventually able to put those distractions of pain and frustration out of his mind and deal with whatever tasks were before him.
At one point in his training, he was taken to a remote location and left to survive on his own, living off the land. It was during that exercise that he met his wolf companion. He envied the freedom the wolf enjoyed, and from that day on, he pledged that he would feel that same freedom once he had learned what he could from his master.
Eventually, he finished his apprenticeship. He fled from his tribe, ran without direction, knowing only that he needed to get away, understanding that he could not continue to be surrounded by their evil and brutality. He and his companion were approached by a priest of Sarenrae, who took Makvor in. He learned that he was not destined to be the same as his father's people, and that he could be redeemed. That priest gave Makvor his tattoos, to cover the scars of his childhood and training.
Makvor left the priest, eventually, and set about with a new appreciation of the beauty of the world around him. Unfortunately, the fact that he has been redeemed is lost on many of the people around him, so he will go out of his way to show that he is no longer solely the product of his orcish heritage.
