The Moment of the Magician (Spellsinger #4) by Alan Dean Foster

A POWER IN THE LAND

The call came from the far South of the strange world where Jon Meriweather was stranded--where animals walked and talked, and where magic really did work. It came to Clothahump the magician, a cry for help from a beleaguered city, held in thrall by a darkly powerful magician.

Reluctantly Jon and a rebellious Mudge set out--only to discover that the evil they face stems from Jon's own world. And if Jon is to conquer it, he must risk never, ever returning home. . .
