A key part of the Chalice World is the Blasted Lands and I have started a page for it here.
The Blasted Lands
This harkens back to the first iteration of this setting where humans came to the world on a great ship to escape earth just before the apocalypse. That was a White Wolf Vampire and Wereolf type game my group played in and I created this world as a sort of "What If" setting for GURPS.
Shadownaughts were inspired by mummies and led the evacuation, taking mages and wildkin with them. I have long held a fascination for Egyptian mythology and thus it plays a key part of the background and history of this world.
