Azrael's Guide to the Apocalypse

From Kickstarter:

Azrael's Guide to the Apocalypse is a high-level, apocalyptic adventure for characters of levels 10-20. Join Azrael, the Angel of Death, and an eclectic band of heroes as you embark on an adventure inspired by the events in the biblical book of Revelation. This journey is not for the faint of heart, and defeating evil will come at a cost. This campaign will challenge the conventions of space and time, thrusting the player characters into the front lines of a spiritual war that spans the fringes of human understanding and mortal history, and will bring each character face-to-face with cosmic horrors and - worst of all - their own personal demons.
