What happens when the world ends? It restarts. Life awlays finds a way.
Millions of years ago, war wiped out the entire population of the planet, allowing nature to take it over. For a long time, the planet was uninhabitable, but gradually nature found its way back, and the planet developed over the years. This time, intelligent life is evolving differently. There are many different species, sometimes only one of their kind, living together, alone, in tribes, and speaking many different dialects. Your actions will decide how these small communities develop.
