Aarbron was born so strong that Maletoth, a reaper of spirits, saw in him the potential to hold a great power. Maletoth kidnaps Aarbron. While Aarbron's mother leads the search of her son, perishing in the process, Maletoth brings Aarbron to the Gate of Souls, where he ordered the Council of Mages to corrupt Aarbron through magic. Aarbron becomes a monstrous warrior-servant manipulated by Maletoth for his quest to conquer the world.

Eventually Aarbron became known only as 'The Beast' and he begins to fight against the corruption. Eventually able to see that he has been manipulated all his life, he turns on his master and slays Maletoth before taking over his kingdom.
