“Otherworlders” is a category for stories defined by outsiders and crossings: characters who come from—or are thrust into—worlds not their own. Whether through portals, summoning, starships, reincarnation, or dimensional glitches, these tales center the shock of arrival and the friction between cultures, magics, technologies, and laws of reality. Spanning fantasy, science fiction, and horror, it includes portal fantasies and isekai, alien first-contact and fae intrusions, multiversal quests, exiles, and visitors among us. Expect wonder and disorientation alongside questions of identity, belonging, hospitality, and the ethics and costs of entering—or being invaded by—another world.
