Asmodeus

Currently the ruler of the Nine-Hells though this is in constant flux between many of the Arch-demons. Asmodeus tends to see the larger picture and plays very long games.

During the First Planar Age Asmodeus convinced the Original Aasimar from the Land of Dranik to convert to worshiping him, through the process they gave up their wings to inherit the power of Fire and became Tieflings. Through many slow workings Asmodeus set about to start the First World War, called The War For Interna. At the end of the war there was a showdown between Asmodeus and Helm, and regardless of the specifics, the resultant clash left a scar that perfectly bisects the seas of Interna, creating an impassable cleft called #Helmscar.

Asmodeus and Helm both disappeared, though they are both regularly worshiped. It is rumored that Asmodeus is simply back in the Nine-Hells, but occasional whisperings indicate he may be lost elsewhere.
