Underworld



The Underworld is a place where evil beings, such as warlocks and demons, live and practice their black magic. Most demons were born, hatched, or created there. It is a place many would describe as hell which contains deep underground chambers, caverns, and volcanoes. It is a dark place due to the limited light which only comes from lit torches, fires, and even cracks in the walls.

The Underworld, as it's name suggests,is under the surface of the Earth. It 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, like how Cole led the Charmed Onesand Leo around many times or how Gideon teamed upwith Barbas in It's a Bad, Bad, Bad, Bad World, Part 2.

In the comics we can see that they're unknown creatures flying.
