A Cardassian colony where Enabran Tain, former head of the Obsidian Order, is living in retirement when Bashir seeks him out in The Wire.
In The Wire, set in 2370, Garak collapses from the failure of a cranial implant that the Obsidian Order gave him to resist torture and that he has been using to dull the misery of exile. To save him, Bashir needs information that only Garak's old master can supply.
Bashir takes a runabout into Cardassian space and finds Enabran Tain at his home on the Arawath Colony. Tain, genial and thoroughly informed about his visitor, already knows why the doctor has come.
He agrees to provide the data Bashir needs, explaining that he wants Garak to live a long and wretched life in exile, which he considers a fitter punishment than death. The meeting is the first appearance of Tain, who returns in Improbable Cause and The Die Is Cast.
