The main setting of the rest of the series after the destruction of the Liebe Delta, and the target of the Orbital Security Bureau, so much so that they've justified destroying Hyperion with the Blue Impulse's Vital Guarder to try and destroy them. The Ryvius is one of two Vaia ships whose Sphixs have been manifested, but is also the only one with a humanized one, Neya. The other ship is basically stripped of any humanity but the desire to kill Neya.
