The Glass City Covenant

A city turned to glass hides a heart that must never stop beating.

Deep beneath the vitrified ruins of the Glass City, Rorak Therenoor and Callidora Wagonwright uncovered the truth behind its destruction: centuries ago, the mage Iskandra sacrificed an entire city to trap an entity that could not be killed, only bound. Now, with the seal weakening and Iskandra long vanished into the northern mountains, the pair must track down the scattered binding shards and complete the binding ritual before the failing seal releases what it was built to contain.
