Homebrewed setting that kind of feels like Faerun with a Dark Souls edge. I've got writer's block trying to think of how to reveal some valuable info to my player characters. They know the apocalypse is coming, and know they cant prevent it, but they do have options for what come next.
This takes some context though
The nine archdevils we know: Asmodeus, Tiamat, etc. are not the original rulers of their respective levels of Hell. The original nine were banished by the Sun god to the furthest reaches of space, long before recorded history.
~1500 years before the campaign start, Emperor Althazar Ekhel made, in secret, seperate warlock pacts with each of these original banished devils in order to gain power and usher the world into a golden age of 'peace'
The people loved him, and he was meant to be coronated as a living god, so upon his death, he would be added to the pantheon (it is known that especially legendary mortals can do this in this setting). His wife, the empress, discovered his dark secrets and during the coronation, when he was vulnerable, murdered him.
Upon his death, his soul was fought over by the nine, and in the void of the far realm, the ten of them became one, with Ekhel as the main controlling force.
1500 years later, the Tenfold King has found his way back to the prime material and plans to turn it into the tenth layer of Hell, with him ruling over all of them.
About halfway through the campaign, they figured out that the only way to truly defeat the Tenfold King is by killing him in Hell. Otherwise, he'll just regenerate somewhere in Hell and come back. So, they have decided to let his cultists go through with their plan to make the prime material the newest level of Hell, so they can kill him for real when he shows up.
