Unique Item: Bull’s Horn

Geryon carries a great horn made of bone.

As a full-round action, he can blow this horn and summon 5d4 fiendish minotaurs. The minotaurs appear immediately and act on his turn. They remain and do his bidding until their death. This horn can be blown three times per week. Good-aligned creatures touching the horn take 5d6 points of electricity damage each round they touch it (no save).

Organization solitary or troupe (Geryon plus 2–5 bone devils or barbed devils)
Treasure triple standard

Geryon, the Great Serpent, rules Hell’s fifth plane. His fortress, a large iron citadel located in the heart of a great city, is situated at the center of his plane. Geryon often leaves his fortress to wander the city, but rarely ever journeys beyond the city’s gates. The city is a large, dark place filled with all manner of filth, waste, and creatures. Geryon is one of the most powerful arch-devils (by physical standards) and enjoys displaying his physical prowess to any who would watch, often destroying pit fiends or minor dukes for sheer pleasure and entertainment.

While he is weaker than other arch-devils (in station and overall power), he has allied himself with Mephistopheles and as such is feared by many. For all of Hell’s inhabitants know, if any can wrest the throne of Hell from Asmodeus, it is Mephistopheles, and Geryon wants to make sure he is on the winning side when the time comes to challenge the current Overlord. Geryon is 20 feet tall and 30 feet long. He weighs about 8,000 pounds.

Servants of Geryon

Followers of Geryon are evil humanoids that revere serpents, some clans and tribes of lizardfolk, and several inphidian communities. Devout followers of Geryon are called Serpent Masters and must sign a pact of evil with Geryon. Serpent Masters can receive spells from Geryon and are granted access to two of the following domains: Evil, Law, and Strength.
