Dark Place

"The Dark Place is from where Demons first came from. It's our last vestige of freedom after being subjected by humanity and their cursed Blessed Magic!"

- -Satan The Dark Place is an alternate plane of existence, as well as a separate dimension. it is the place of origin for Demons, Devil's Magic. and various other supernatural entities.

Description
The Dark Place is perceived by humans as a great abyss or endless blackness, but in actuality is a swirling contradictory dimension of solid, liquid, gas, plasma, and various other states of matter, filled with swirling masses of eldritch tentacles(the true forms of Demons) it can be seen by anyone of demonic origin/ancestry with the use of Devil's Eye. Interestingly, humans must take a form of their own their, unlike the opposite on Earth. Demons are free form there and often accidentally end up fusing into one, single, more powerful being. The deeper you go into the endless depth of the Dark Place, the stronger demons await, with Satan himself at the bottom. The Dark Place is a walking contradiction, paradox, and conundrum all in one. It is also called Hell or the Demon Realm. Time does not flow within the Dark Place, and most Demons often pass thousands of years in what could be best described as seconds for them. The dimension is very detrimental to humans, and a human cannot spend long periods in there without severe consequences.

Trivia

 * The reason Demons have to take a form is because human minds cannot comprehend their true forms.
