Sorcerer

Sorcerers are magic users that practice sorcerery, dark unnatural spells, and devining spells, usually gained from the assistance or control of evil spirits or demons. It seems that most Sorcerers are evil, though its implied that some must be good by the fact that Edward trusted one (though that one turned out to be evil as well).

A Sorcerer had promised to cast a spell to bring a child to the wife of King Edward in trade for the Magic Mirror. However the sorcerer had no intention of keeping his bargain.

Mordack was said to be a Sorcerer as well as a Wizard as he practices magic from both sorcery and wizardry. He used spirits to shrink down the castle and whisk it away from Daventry.
