Solum
Solum was a ringed, inhabited planet and the homeworld of the Vau N'Akat. () 

The Diviner referred to Gwyn as the "Progeny of Solum". ()

History
As of 2384, Solum was habitable and prospering, the Vau N'Akat believing they were the only sentient species in existence.

In the late 24th century, the United Federation of Planets made first contact with the Vau N'Akat. Fifty years later, the planet had descended into civil war over whether to pursue relations with aliens, which resulted in the fall of their civilization and the near-extinction of the species. An individual calling himself "the Diviner", who believed himself to be the last of the Vau N'Akat, traveled back in time to the 2360s with a plan to stop First Contact and prevent the war. ()
