Devouring beasts above. Demons below. Corruption runs through Gabriel's veins. It threatens to turn him into a demon's vessel. Racing against time he heads for the one place that can help. Draskel Citadel, home of the Ishgallian Clans. Its mighty warriors fear no enemy. In a thousand years its walls have never been breached. More importantly: they know how to cure Gabriel and restore Stormbringer. But all is not well in the citadel. An ancient threat has returned. One thought to have burned away in nuclear fire. Reclaimers and Ishgallians stand at death's door against the devouring tide clinging to one desperate hope . . . The Heart of Iron.
