The Hero's life after saving Antaloor was supposed to be quieter. Then a letter arrives from DarPha, urgent enough to send him traveling across the continent. He arrives just in time to watch a group of robed figures apparently murder DarPha before retreating through a magical portal. The disappearance turns out to be connected to a mystery that goes back decades and to a new race of rat-like creatures—the Tenebrae—who have their own designs on Antaloor's destruction. Two Worlds II: Call of the Tenebrae is a standalone expansion that brings a new threat to the world of the Two Worlds series.
