Only one version of Demonbane is porn, which later changed into all-ages with PS2 version, additionally added new contents and replaced the porn with much better stuffs. Anyway, infinite multiversal, higher dimension vs lower dimensional or shit like that is pretty much common in Demonbane verse. Or how Demonbane has its own hierarchy of Stories, Hyperdimensional Space, Nonexistent Physiology, Azathoth's dream being absolute infinity but still got one-shot by Vortex Blaster's Lemuria Impact, etc... I could go on and on.
