For this uncanny place is our Earth, far, far, far into the future, after our civilization and seven others have climbed, peaked, fallen, and been rusted over. More than one alien invasion has occurred, and more than one alien species has mingled genes with humanity. A new civilization has arisen, but hasn't really gotten past the middle ages. The perplexing debris of past civilizations, from humming obelisks and transdimensional portals to enchanted amulets and portable CD players, is everywhere. The people of earth call these weird objects "filled-with-power-things": numenera.
Welcome to the Ninth World, the setting of Monte Cook's Numenera. I would say, "come on in, the water's fine," but it's probably filled with flesh-eating microdroids or laced with bubble-gum flavored psychotropic drugs or something. But forget the water, there's so much here. This place is so ancient, and vast, and tremendous. Let's explore!
