Demon Realm, Holifen

A pocket dimension where demons reside. A twisting, physics-defying realm, there is no ground, no sky, no air, and no gravity, rendering it impossible to survive in without highly specialized gear.   To mundane eyes, it's a realm of a sickly yellow color shot through with swirls of acrid pink and orange, with suffused, sourceless light that permeates everything. A heady stench emanates from every noxious particulate, like some foul cross between dog feces, battery acid, and sun-baked human vomit. Miasma makes a fine mist here, black, pink, and orange particles swirling without purpose. To those gifted with astral sight, the realm is even worse, as one can make out fragmented, corrupted and blackened souls swirling all about. To one gifted with extraperceptive hearing, they might wish to turn off their senses, as lamenting screams and moans and cursing whispers hiss from every direction.   There is no rhyme or reason to be had here, this being a realm rent in the fabric of reality by beings long dead. If one is unluckier still, as if being within the dimension wasn't bad enough, demons can be spied drifting through the vast, empty space, or, continuing to defy physics, walking along as if there were a floor with functional gravity.
