Colossal era (NONCANON)

Colossal Era: A book covering the lives of people on the Earth of Overus, an infinitely large Earth. The current extinction war (World War 3 in CE) has destroyed most of the lands, leaving people to live in ruins as every nation and faction fights each other. Technology is kept up to 1999 levels, but mostly uses technology from WW1 and WW2, as well as technology from other universes, like Fallout.The god of Overus, being Sergey Taboritsky, fights the half-god, Philip IV. He once trusted Philip, but Philip left his brutalist archangelic regime after Philip's first wife, Loji, was assassinated by Sergey while on stage with his god powers. The main source of assets and people coming to Overus is that the project takes all things, people, and animals from other Earths and transfers them to Overus, while the Earth's cores are used for energy. Another important thing is cinan crystals; they can be used to make portals, make someone immortal in terms of age, and much more.(All the rights to universes not made by me go to their respective writers and owners)
