Garmaddon

Garmaddon, also called Garmadon the Terrible, and Garmaddon the Necromancer, was a Yang sorcerer, and former court mage of King Olaf One-Eye. He was immensley potent with magic, as he was capable of combating and defeating Merlin. He was cruel, very arrogant, and felt no pain or fear. He was corrupted by Anubis, his patron, and was a faithful follower of the demon.

He, alongside his former King Olaf, waged war against the Brickston Empire in what culminated as the Castle Wars.
