When the god Tetheus won the battle over the land of Icarus and banished his rival Ercanet, he expected the matter settled. Ercanet chose to take revenge not on Tetheus but on the humans who sided with him — spreading suffering across the land and installing his own agents within it. Dreus, a soldier of the Coshark Mercenaries, survives an ambush that kills his entire unit when a comrade pulls him out. The wizard responsible is one of Ercanet's henchmen. Dreus survives to swear revenge — for his unit, for the land, for everyone the wizard's master has harmed. The investigation that follows eventually reveals Ercanet's full plan, and stopping it requires a journey into the underworld itself.
