Wizardheimer went to school at Koopawarts, where he learned much magic, especially necromancy. After graduating, he began serving Bowser. Bowser was pleased by his powers, and sent him to cause terror in Dinosaur World. There, he found a ghost house in a spooky enchanted forest. With his necromany powers, he enslaved the boos and other ghosts inside, and claimed the house as his home.
