Every army needs a mascot.
For one particular evil wizard, that mascot is Grugush. He is a massive ogre who has been trained in the ways of war since he was a child. He is a master of the greatclub and an accomplished archer. Grugush prefers to lead the charge into a battle, using his extreme speed to close with his foes before they can loose spells or projectiles. He loves to swope in, bash his foes, and then flee.
