A centre of the distributed Cyberian Network. Seen from Sol this is the brightest star in the constellation Boötes (the herdsman). It is a post-main-sequence orange giant (spectral type K1.5IIIp). Arcturus is 34 light-years from Sol. It has an absolute magnitude of 0.2. This star is a member of a population of stars that originally formed a small separate galaxy that merged with the Milky Way more than a billion years ago.

This star is deficient in metals, and has several small volatile-poor planets that have been baked by the star during an earlier red giant phase. The Cyberian Network have built numerous dataspheres on, inside and around these worlds that support a large number of cybercosms, including those where the Arcturus Institute of Alternative History was first founded.
