Wizard Fantastic by Martin Harry Greenberg

From Merlin to Gandalf the Grey, wizards are one of the cornerstones of magic and fantasy. There's nothing like an evil wizard for a good plot twist, and there's no better way to improve your odds of surviving the battle or rescuing the kingdom than to have a benevolent and powerful one on your side. And this all-original volume offers wizards to suit a reader's every fancy, from sorcerers to geomancers to witch doctors to shamans. So prepare to enter the many worlds of spellcasters both dark and bright but be warned: without the right counterspell, the reader may not be able to find his/her way back.
