Technology and science-fiction dreams shape the Countless, Changelings who build new homes in Subspace and seek harmony with humanity. Their realm lies beyond ordinary sight, where shattered prophets and hidden secrets threaten an already fragile peace. The game describes six regions of Subspace and four Countless clades, including the mysterious Oppies. It provides rules for creating UFOs, strange mobile Freeholds, along with new realms, five ready-made characters, and adventure ideas for exploring this setting.
