I call it the PerVerse. A universe where a corrupting influence is spreading. Warping people places and things to match their deepest sexual fetishes, in the case of places and things, they are twisted my the energies and fluids from the populace on a prison place and testing planet by a devious, heartless, amoral and almost godlike alien race who dump their expiremental failures and prisoners onto this twisted world to better develope weapons.
