Divided We Stand is a multiple-mythology roleplay set in modern America.
The gods of the old world have taken up residence in America, and of course, the rest of their worlds (their enemies and their allies) have followed. Different civilizations have take a liking to different regions--and they're very territorial.
The only thing that keeps their border disputes from raging into full-out, civil war is the Bureau. The Bureau of Mythological Registration and Regulation (founded in secret by the US government) has offices in every region.
But the gods are not accustomed to rules. Greek, Norse, Aztec, Egyptian… With so many conflicting pantheons in one nation, how can a semblance of peace remain?
