From publisher blurb:
The Embodiment of Evil
For those familiar with the occult world, Lord Orkus (PL 16) is well known for his strength, his brutality, and his fondness for personally executing his enemies. What truly separates him from other dimensional conquerors lies in his godlike intelligence and his vast expertise of the mystical arts. However, his vast powers are countered by his great arrogance and overconfidence.
Meeting the Merlin of Earth in battle many times, Orkus, Lord of the Underworld, cannot be slain, that is, as long as he resides in the Underworld.
Iconic Legends. Because sometimes you a need a character everyone knows, even if they're meeting them for the first time.
