Belros was born to a single human mother, Lorena, who received pity for having to have birthed a bastard son. While the rest of town looked at the boy with disgust, his mother loved him dearly. She did her best trying to integrate him into town by taking him everywhere, though this usually resulted in rocks being thrown at him by other kids whenever she wasn't looking. He wasn't allowed to do anything about this, because Lorena feared they'd take him away should he ever lash out.
But one day, he did lash out. As he was hiding behind his mother to avoid any objects thrown at him, he saw the attention wasn't on him. Instead, the bullies targeted a small boy wearing tattered clothes, who didn't have a mother to protect him. Being fed up with these bullies, Belros took it upon himself to protect the boy. He charged the group of bullies with a fearsome shout, throwing two of them to the floor and knocking a third unconscious before standing over the boy, who had curled up into a ball at this point, to protect him.
While the townsfolk liked him less at this point, he did gain a single friend that day. A friend that looked up to him and, inspired by Belros' act of kindness, decided he'd protect the innocent from harm just like the half-orc did for him.
Years passed and things were finally looking up. To see Darrel, a human child, and Belros play along so cheerfully made the rest feel more at ease with the half-orc, too. His mother was happy to see her son finally enjoying life. But happiness wasn't meant to last for Belros. When the two spotted a thief robbing someone, Belros convinced Darrel to assault him, rather than alert the guards. The two snuck up and jumped the thief, who threw them both off, stabbed Darrel and ran away. From that day, Belros fell into a depression and rarely left home anymore.
At the age of 16, his mother had fallen ill. Bedridden, she wasn't able to care for her child, so it was up to her son to make a living. By now, the boy had become taller than most, his skin pale and his hair long enough to easily cover his pointed ears. His small tusks and thick skin were the only things that seemed orcish about him at this point, but it wasn't unsettling enough to deny him as a strong workforce. Belros took any and all jobs he could, just to provide for him and his mother.
In time, the people grew less wary of Belros, but this wasn't the case the other way around. Watchful and always on guard, he lived his life doing tedious and hard work. His watchfulness and distrust of strangers helped him catch a pickpocket red-handed. With Darrel's death in mind, Belros restrained the thief by grabbing his arms, then called for help. The man tried to escape for a second, but froze in fear after staring into Belros' stern gaze. Realizing his potential, the guards offered him a position, which he accepted gladly.
At 22, his mother died of her illness, leaving him alone in this world.
