Have you heard about how the Nahuatl religions had a Hell/Underworld of sorts that was a real, physical place? It was this spooky cave system that they thought spirits went to in death.

And it was terrifying, and elaborate as fuck (though I'm no expert whatsoever, so for the life of me don't quote any of this). A whole physical and spiritual journey with distinct stages and terrain, like the levels of Dante's Hell, only that you have to pass through them sequentially unless you somehow have favour with the gods and can afford a shortcut.

Reathos might like it if you did a physical-spiritual combination like that underground, so long as it's not too close.
