Spines was born in a small orc village and didn't get much time to know his parents. At a very young age, his village was raided and his father killed along with most of the male orcs. The children were seized from their homes and taken to the city to be raised in a more "civilized" environment.
While in the city, Spines was taught in the monasteries among the monks in the way of unarmed combat. He enjoyed hurting things with his hands, but he knew he didn't fit in with everyone else. He felt unintelligent and different.
After years of internal struggle, his primal instincts overfilled him, and he flew into a rage. He ran away into the wild to find some sort of peace. While out on his own he discovered an abandoned village and searched through it. There he found several things he recognized from his earliest memories.
He didn't see any signs of struggle in the house, so he had no way of knowing whether his mother was still alive or not. To this day, he continues searching for his mother, just hoping she is alive somewhere.
