Although Orcus doesn’t have a strong following on Zaldara, he has far more dealings with other worlds than most of Zaldara’s demon lords. His cultists maintain that the Prince of Undeath is merely waiting for matters in other worlds to resolve themselves before turning his gaze upon this world as his next prize—and that when he does, his faithful shall be rightly rewarded for preparing the way. Of course, fierce competition for worshipers with the cults of Zura and Kabriri is a more likely reason why Orcus’s cult on Zaldara isn’t more widespread.

Orcus appears as an immense, fat humanoid with a ram’s head, bat-like wings, cloven feet, and a long tail ending in a stinger. His legendary weapon, the Wand of Orcus, is never far from his taloned hand. His Abyssal realm of Uligor is an entire world of undead-haunted ruins, frozen seas, ragged mountains, and hideous deserts and swamps. Orcus shares this realm with a large number of evil thanatotic titans, not all of whom worship or even ally with the Prince of Undeath. Large regions of Uligor are scarred by the unending civil war between the titans. It is unknown what shadowy force directly opposes Orcus on Uligor, but his war with this mysterious demigod has lasted for millennia.
