The Warp

Description
The Warp is a very nasty place being known as Hell where in the Warhammer 40k Universe it completely overshadows heaven meaning if someone dies they'll be heading into this place even if they are good thankfully that influence doesn't extend to the afterlifes in the multi-universe but doesn't stop the chaos gods pulling it in to merge those realms with theirs waging their never ending war on mortals, deities, and against each other.

It is a frequently used headquarters used by the most evilest villains that are allied with the Four Chaos Gods.
