The rotting God universe

Towards an entropic, Souls-like dark fantasy of grey vistas decomposing into black hole swirls:

Something that would go like:

Pressure clocks pinging on our wrists and weapons at the ready, we wander around the insides of massive space whale carcasses dodging the other gas-masked inhumans scavenging for the last dying embers.

(Compare the charnel ground.)
