Since I am new, maybe this idea already showed up. Haven is after the apocalypse , all humanity is dead and revived by ancient magic, let loose on the earth anew. The gods, aka devs, nuke this world whenever it is they see need to start over.
At least, I like to think of it like that, since there are rotting farms all around me and I am basically scavenging all the stuff into my own little farm. That, and humans have to relearn the basic ideas of farming and building things.
I haven't gotten into looking if there truely is any lore behind the world in Haven, so I kinda like coming up with my own ideas. Anyone else?
