Cadaver hatched in a graveyard located in the Mud Kingdom, alone. He was found sitting beside a dead MudWing SeaWing hybrid, the hybrid's blood staining his talons and face. A troop of MudWings found him, and alerted the MudWing queen. The queen ordered for her advisers to deal with the seemingly murderous dragonet. The advisers locked Cadaver in a cage and sent him to the Sky Kingdom. They got there and left Cadaver in the cage for months. Then they sold him to two vicious SkyWing SandWing hybrids by the names of Dawn and Dusk. Dawn was less vicious than her twin, and treated Cadaver better than Dusk did.

Seeing as he looked pretty ferocious with all of the hybrid's blood still on him, Dusk, thinking that Cadaver was a monster, chained him up in the darkest place he could find, and muzzled his jaws shut so that he couldn't breathe fire or bite them. Dusk was the leader of a group of semi-crazy SkyWing hybrid who worshipped Ex-Queen Scarlet and her obsession with gladiator fights. They called themselves the Talons of Bloodshed. Dusk forced Cadaver to fight against a few dragons each day for his amusement. Cadaver, not knowing any better, thought that Dusk was raising him normally.

For ten years, Cadaver fought for Dusk's amusement. Dawn, watching from the shadows, knew that the tribrid deserved better, but when she complained about it to her brother, Dusk threatened to rip out her tongue, so Dawn didn't complain, though she hated seeing Cadaver treated the way he was. One day, Dawn snuck into Cadaver's 'quarters' , which was really just a pit in the floor with bars over the top, and undid his chains. They managed to reach the exit, but were caught and brought before Dusk, who ordered Cadaver to be punished in front of him. After they finished, the guards took Cadaver back to his cell, leaving Dawn with Dusk.
