A reality within the Metareality-Web that's composition and layout made it the perfect punishment for any inter-reality criminals who have committed actions of 'beyond Multiversal omnicide'.
This accursed place is comprised of a mixture of Ω particles and Σ particles, making it a reality made of 'bad karma itself', along with that, those 2 types of particles aren't exactly the most stable combination... and by that I mean every there are explosions the strength of more than 1000 atomic bombs in every square centimetre of this realm, within every, single, second.
Of course, for any non-mortal being to *ACTUALLY* survive this "PURE ENTROPY AND RAGE FILLED DIMENSION", some form of 'god level armour' is absolutely required.
It is also home to a being older than time...
