Hell's Bells Extended Universe
Hell's Bells and all its content. What a project this'll be...
Science-Fantasy Action-Horror
Oh man, where to even begin... I don't think this is the place.
The Big Bang, same as the real one, with cosmic gods being birthed a few thousand years afterward and going on to assist in the formation of many still-surviving galaxies.
Varies from race to race. Humans are doing pretty good and had the beginnings of a Dyson Swarm going, the Astrals have fully functional warp drives and widely used FTL, as well as rapid genetic modification technology to adapt to the atmospheres of various worlds.
Real life but with extra steps. We got magic and psionics, you know how it is.
