The location of the Starfleet stockade where Ro Laren was imprisoned after the fatal away mission on Garon II, until Admiral Kennelly arranged her release in 2368.
Jaros II is the site of a Starfleet prison. It is mentioned in the Next Generation episode Ensign Ro and never seen.
While serving on the USS Wellington, Ro Laren disobeyed orders during an away mission on Garon II, and eight members of the team were killed. She was court-martialled and sent to the stockade on Jaros II.
In 2368 Admiral Kennelly has her freed and assigned to the Enterprise-D for a mission to locate the Bajoran militant Orta, to the dismay of Picard and Riker, who know her record. When Kennelly's secret dealings with the Cardassians come to light, Picard offers her the chance to remain in Starfleet aboard his ship, and she accepts on condition that she may wear her Bajoran earring.
