Shadow of Vengeance

No Rest for the Wicked. "When a breach to Penumbrum suddenly appeared, havoc and death invaded the mortal plane. Noble merchants hired a renowned group of adventurers. Their leader, Orella forced the undead back through the breach, but was dragged with them. Ten years later, a new breach to Penumbrum emerged in the same place of ten years before. However, this time, the creature leading the attack was a powerful Death Knight, a corrupted form of Orella herself. Will the adventurers manage to deal with that loose end or will they share the same fate their leader had many years ago?"
