Lord Jubilex is a Greater Demon who commands the forces of the Underworld. Summoned 500 years ago, it was only through sacrifice and unity that the surface world was able to banish him to the Underworld. Lliira, a goddess of a chaos and the sister to Jubilex, was able to defeat him in the Underworld and banish him to the Prison Plane, a plane for holding unspeakable creatures. For reasons unknown, Jubilex escaped this prison, fleeing Lliira’s justice in the Underdark. Now he plans to return to the surface world to make it his paradise. A few brave adventurers battle to stop him.
