In early 4921 ksepo, the Rotomem, the sole colony ship of a human out-group, found its way into the Ksreskézaian Empire through a series of wormhole filaments which have never been retraced. By early 4922, they had found their way to Ksreskézo, the Oksinení homeworld, and by the end of 4922 the Rotomem had been confiscated and the Rotomemí were enslaved. The story of what happened afterwards is recounted on the page "Rostyaekía."
