The Pandahem Cycle I by Alan Burt Akers

Four hundred light years from Earth, Kregen is a marvelous world, peopled by wonderful beings, filled with the light and clamor and furor of life lived to the hilt. But Kregen has its darker side, where horror and terror bind innocent people, where sorceries rend reason, where injustice denies light.

Called to be the Emperor of Vallia, Dray Prescot, with his comrades, has vanquished poor old mad Thyllis, Empress of Hamal, and now seeks to create a fresh and lasting unity among all the nations of Paz. They all face a common foe in the Shanks, the Fishheads who raid their coasts. And, there are worms within the bud, secret enemies who desire only to drag all down for their own selfish ends...
