The port-city of Gleda is under siege. Agmar, bard of Seltica, is one of a band of Selts who have joined the Ropeuan army of the lord Wulfstan as he closes a ring of steel about the city of his forefathers, lost nearly a century before to the grim Fiks when their dragon longships sailed out of the icy north on a wave of brutal conquest. While the horrors of the siege play out, far beneath the city an ancient power stirs, calling across the centuries to one who might take what it holds and see the destiny of the very gods.

Altar of Fallen Gods is the second of the Song of Agmar Tales.
