Mystic Warrior — Tracy Hickman; Laura Hickman

Thrice upon a time, there were three worlds of magic. On one world faeries suffer in a war against centaurs and satyrs. On another, goblins scrabble about the ruins of giant machines. And on the third, humans re ruled by theocracies that worship five immortal dragons. The task of the priests: to gather the insane for dark purposes.

Galen Arvad, a young blacksmith, is plagued by fantastic dreams and tortured by common objects that talk to him. Unable to hide his eccentricities, he is hauled away and plunged into a deep chasm of danger and intrigue. But Galen's madness is a sign of magic that can bridge realms and strike down dragon lords. Can Galen learn to use his power--before he's destroyed by the monsters that rule his world?
