The world of Earhas.

500 years ago. We had a high-tech golden age. Now, the land has regressed to medieval kingdoms built upon the ruins of once mighty cities. In this unique post-apocalyptic, dark fantasy, hybrid world, you may write your own stories. Be they tales of how an isekai protagonist restored hope to this doomed world, how an ai overlord conquered it fully, how a simple citizen of this world struggled just to get by, or any number of other kinds of stories. Let the world of Earhas be your sandbox.
