The Astral Plane.
White as far as the eye could see.
It was a space between dimensions.
A plane between multiple planets and parallel worlds even.
And for a fissure to open into any other world or planet, they needed to pass through this space as a gateway.
Originally, this was Gaya's abode.
Primordial Creator of Arcanora and all the other residing planets that had now met their ruin at the hands of the Demon King, Beelzebub.
That being said, no living being is ever supposed to survive there.
There was no up, no down.
No concept of time and space…
Just infinite, boundless white…
And yet, Amael, having turned himself into pure energy during his last battle with Beelzebub 15,000 years ago as a gamble of sorts with the help of his authority ((Rule Breaker)), found his way to the plane and adapted to it.
