There is a last world. It is not so much a place of lost things as a place of glorious endings, settled by isekai heroes who never made it home and haunted by the ghosts of the mighty. Our story begins when the current that draws the greatest things of yesterday to this happy world is reversed by a thoughtless traveler. We paint a picture of this strange apocalypse through the stories of its victims, whisked away to fantastic worlds where they are unwanted.
