Here are the stats for Emirikol the Chaotic, as they appear in Monte Cook's adventure, A Paladin In Hell. It would have been so cool had they also provided a portrait of Emirikol, but sadly they did not.
The Adventure begins with the funeral of a paladin, with his body, the attendees and the entire temple being dragged into the depths of hell. The players set off to save the attendees, and recover the temple and the paladin's body, and discover why they were sucked into hell in the first place.
Emirikol acts as the adventurers' patron in A Paladin In Hell, gifting the adventuring party with an abyssal sailing ship, Demonwing, to aid them in their quest.
Why? Play the adventure, and find out for yourself...
