Tribes of the Afterworld
Civilization Has Collapsed
The world fell apart as the meteors hit. What was inside them caused everything to change. Life died, life mutated, life continued. Those things that survived grew stronger, more dangerous. Humans are no longer the top of the food chain. Humans are even in the running.
(Inspired by the Horizon Zero Dawn trailer, the world is back to a neolithic era with post apocalypse thrown in. Chronicles of Darkness with a lot of changes and we are making it up as we go.)
