Ultima Thule
From Memory Alpha, the free Star Trek reference
Ultima Thule is a planet, where a dolamide purification plant was located. Ultima Thule was the last stop on the route taken by Valerian traders supplying weapons-grade dolamide to the Cardassians.
The Valerian transport Sherval Das visited Ultima Thule in 2369 a week prior to docking at Deep Space 9, suggesting that they were carrying dolamide.(DS9: "Dramatis Personae")
Ultima Thule means "the extremest north" in Latin.
