From publisher blurb:
An island of magic and mystery…
Wellsprings of Quintessence are never easy to come by. But on the Baltic island of Rügen, crays are found in surprising numbers. Once the stronghold of the Old Faith, the island has been contested between the Valdaermen and the Messianic Voices since the fall of the temple-fortress at Arkona in 1168.
where an acient evil has slipped its chains
Island of the Dead God is a setting book for Dark Ages: Mages, examining the island of Rügen, once the center of worship for the Slavic god Svetovid and now the site of a secret struggle between the Valdaermen, Messianic Voices, and Old Faith as to who gets to control the island’s vast, magical resources.
Adding to the mystery is an ancient evil that lies beneath Rügen, free once more to whisper its madness and corruption to the inhabitants of the island.
