Only nightmares lie between the The Great Dream and the Voidlands.
The edge of the Underworld that connects to the Outer planes.
A chaotic reflection of reality.
dark and forboding
The in between.
The Voidlands aren't empty, they are full of nothing.
This is not tour reality, your rules do not apply.
Air, fire, water, earth, life, entropy.
Judgment is final, those that don't conform are remade into something that is.
No need to watch your pockets here, but don't make any deals without discussing the specific terms.
Even the shadows flicker like candles.
