A different plane of existence
A dark maze of underground or volcanic caverns and chambers
The Underworld is one of the eleven planes of existence. It resembles a dark maze of underground or volcanic caverns and chambers. The Underworld is the plane in which most of the Demonic Hierarchy resides, including the leaders of the forces of evil, most notably the Source of All Evil and the Triad.
A Demonic Hierarchy exists in the underworld, its purpose is to maintain order and control over the many evil forces that exist there. Typically, this hierarchy is led by the Source of All Evil, though other demons, such as the Triad, serve directly under him and assume control when the Source is vanquished. Various evil magical beings reside within the underworld, including several Demonic Factions, Darklighters, and even certain warlocks, who are considered to be at the bottom of the hierarchy.
This realm is a vast place, too vast for any good being not familiar with it, to travel through it accurately, without the help of a demon. Furthermore, the nature of the Underworld itself causes the sensing of good beings to become more limited than they otherwise might be.
