Arcturis VIII is the home planet of its eponymous race and is the eight planet of the Arcturus System, but it was destroyed after an attempt of complete mechanization by it, thanks to the Epiphanies of Guidance.
It was replaced by the Cardianon Mothership, an enormous space fortress that took over the original planet. The planet was inhabited by the reptile Cardianon, but the influence of the Epiphanies of Guidance caused this race to evolve and create an overdeveloped civilization.
