Songs from the Drowned Lands

From the back cover of the Ace first edition: Across the sea they wait, wrapped in a mist of sorcery and wonder. Their people are wise, noble and brave: learned in the shaping of order that we call magic. But among them are those who have courted chaos, calling to them creatures out of dream, tearing a hole in the great pattern - and to that opening the Old Gods, the Lords of Chaos, are flocking, massing their dark powers to make the waves rise up like mountains, to doom the Grey Isles and their people forever beneath the sea... Oh, hear their story!
