Astral Realm
[Realms]
There are different dimensions in this nature and different beings reside in these different dimensions.
Humans, elves, dwarfs, the normal energy beasts, and other beings that a human can naturally perceive reside in this normal perceivable realm, [{( Cognition World )}].
Demons, the real low rank and noble strong ones, reside in the lowest realm, [{( Hell )}]. And this hell itself is believed to have nine different levels, but that was in that specific realm, so they were called [Floors] of a realm.
Just like how demons reside in the lowest area of the world, gods reside in the highest one, [{( Heaven )}]. And there are believed to have six such [Floors] there too. The six levels of heaven are divided by the strengths of lords and gods.
Aside from them, there exist another three 'known' realms.
