Eddington's prison starbase
This United Federation of Planets starbase was the location of the brig that held Michael Eddington following his conviction for betraying Starfleet in 2373. It was at this base that Eddington received counseling sessions, psychological evaluations, and rehabilitation seminars.
Sisko arrived at the station to relay the message to Eddington, who dismissed the entire interaction. When Sisko offered Eddington his freedom in exchange for his help, Eddington dismissed that as well, stating, "I want to lie here until the Jem'Hadar blow this place to pieces, and me along with it."
