It's in the title! What's your current campaign or setting you've been playing in recently?

I'll start:

I've been running a homebrew game that's gone all over the place over the years. My group fought a doppleganger invasion, overthrew a local oppressive government, battled with a devil cult, and many more odd ball adventures.

Recently after one party member drew the Moon from the Deck of Many things and wished to become "God Emperor" I decided to overhaul the world as a space themed adventure. The party is now playing in an alternate reality where the party member who made the wish is now Emperor but the party's old characters, twisted by some evil magic, are now working against them to bring down the empire.
