Chtaari Realm

The Chtaari Realm is the underground of existence, unfolded under every universe of the multiverse. This place is imaged as a place of chaos as everything can hapen without any sense, time is also weird because it can sometimes flow backwards in some place while flowing in fast-forward in other places. Time flowing is also not constant, it can stop and reverse at any time and it doesn't even match time in universes.

Althrough, life can still exist and it emerges randomly and can disappear as fast as it emerged, living being can also exist and get erased from existence just like it never existed. An example of spontaneous lifeform is Kraalor Chthau.
