The world of Nuclear Spring
Nobody knows who started the apocalypse. Perhaps the fragile peace between humanity and the various alien races finally fell through. Perhaps it was infighting between the many factions of humanity. Perhaps they merely lost control over an automated weapon system that set the dominoes falling. Regardless of cause, what matters is that the bombs did drop. The many worlds of humanity were blanketed in atomic fire, and the following centuries of nuclear winter killed off most remaining life.
But that was an eon ago. The wounds of the Great War have healed over. The ash clouds have settled, the craters have become lakes. Even the radiation has mostly faded to non-lethal levels. The survivors grouped into bands then tribes and now into full civilizations. The end of the world faded into history, then from history into myth. Now the new civilizations of humanity sprout from the ruins of the old.
And on a far flung colony on a moon once known as Eren B, the reinvention of several key pieces of technology and the rediscovery of incredibly machines from before the Fall have set off a golden age of prosperity and exploration.
Eren B is a large moon about the size of Mars that orbits and is tidally locked to a massive, Jupiter-sized gas giant called Eren. (for those who don't know, being tidally locked means that the same side of the moon always faces the planet, like with our own moon) Because of how large the gas giant is, and how close Eren B orbits it, Eren B goes through a total solar eclipse every day, when it passes behind Eren.
There was no life on Eren B before it was terraformed, and so all the life on it is descended from the few species brought over by the original colonists. This has resulted in an oddly large number of niches being filled by various species of birds.
The civilizations on Eren B are mostly at a late medieval to renaissance level of technology, with a couple notable exceptions- Old Tech being one of them.
The continent in the middle (which I still haven't named yet) is currently the only continent I have fleshed out, which is why the others are drawn with nowhere near as much detail and don't have any seperate biomes.
The red horizontal line denotes the equator. The point where it intersects with the central vertical line is where the gas giant is directly overhead. The other 2 vertical lines are facing towards and away from the direction of the moon's movement.
The main regions I've created so far are as follows:
Laroth, the large central desert is mostly split between the big cities built around oases and the tiny villages and nomadic peoples who survive out in the Sand Sea. They also have a vast supply of Old-Tech because the desert has preserved many ancient structures.
Alorgast, a somewhat mongol-inspired empire in the south. They own almost the entire surviving population of horses on the planet.
Teluo, a lose confederation of city-states in the north-western islands and stretching down the western coast of Laroth. They are very, very loosely inspired by the ancient Greeks.
