The Echoes of Heaven Campaign Setting (D20 3.5)
A dark fantasy campaign setting where a monolithic church has fractured into rival factions and holy war threatens the world. Demonic influence from Hell infects the land, while oppression, religious conflict, and racial division shape daily life. Players create and run d20 3.5 characters who confront tyranny, fanatical enemies, and the forces of the Fallen Host. Faith, honor, courage, and combat determine who can resist those seeking to enslave anyone of a different belief, philosophy, or race.
