A star system in which Worf and Ezri Dax abandoned their damaged runabout and were captured by the Breen in the Deep Space Nine episode Penumbra.
The Goralis system appears in Penumbra (2375), the first chapter of Deep Space Nine's closing story arc.
When Worf goes missing after the loss of a Klingon ship near the Badlands, Ezri Dax takes the runabout Gander without leave and finds his escape pod. On the way home they are set upon by Jem'Hadar fighters and run for the Goralis system. The runabout is lost, and the two beam down to the third planet with few supplies and no means of calling for help.
Stranded in the jungle, they quarrel about Jadzia and then spend the night together. The next day a Breen patrol stuns and seizes them. Their captivity leads to the revelation that the Breen have allied with the Dominion.
