Calen had lost his parents when he was five years old, or more precisely, about one year after the voids appeared in the beastworld.
Since his parents were Nomads—people who constantly moved from place to place and were not tied to any tribe—he had to struggle to survive on his own for years. And once he finally entered a tribe, he was not welcomed as a member, but he was turned into a slave.
His master placed a crystal seal on him when he was only ten years old. Since then, he had lived chained by that seal.
Most slaves chose to simply blow their own heads off after one or two years, but for some reason, Calen kept choosing to live.
No, it wasn't because he truly wanted to live. It was because his father and mother had sacrificed their lives so he could escape from a group of demon beasts.
His parents had given him his life, so he felt that he had no right to throw it away.
