Hoseok is the prince of the Kobalos. He is half human because long ago the Kobalos killed all their women and must mate with human women. They enslave human females or "purrai" and use them to give birth to more Kobalos. In the past, they slaughtered every female of their species because they thought the females made them weak. They hung them upside down and let them bleed out on the arena floor. After one was completely drained she was replaced by another female Kobalos. The Kobalos mages delight in a form of entertainment where they force creatures they make with their magic fight to the death in the arena.
