Few things shine as bright as the jewels of Hell
A rare and diseased jewel, a canker fallen from the heavens
“Gold. GOLD. GOLD! Beautiful, wonderous, Gold! I am Rich I tell you. I am the luckiest man alive!”
“Ever in my hand, lies the Blade of the Mad. It’s straight, simple craft is so alluring to me… It drives me to evil, but I love what it does. For the first blood the blade tasted was that of a human.”
The religion believes in reincarnation, but that you will be reborn in the past. People of today are those re-born of tomorrow, with some discarded as trash. The most pure will be eventually reborn in the mythical paradise-like past, where people lived for hundreds, or maybe even thousands of years.
This goes nicely with beliefs into foresight (you know a little about the future because you have been there), but also to many complaints of how things are going always from bad to worse.
