Kether is the only planet in the Aleph Cygni system.
It has one natural satellite (moon), Rispin's End, and there is a nearby asteroid field. Kether is a habitable world, consisting mostly of oceans, though aside from islands, there is one continent-sized landmass. The capital city is on this landmass. Recently the administration of the planet has attracted the attention of Federal authorities due to possible involvement in the illicit trade of the drug Satophil-d.
