In 2375, Decos Prime was the site of a Federation base.
During this time, the Starfleet Chief of Operations at the base was Al Lorenzo. Lorenzo agreed to trade an induction modulator to the USS Musashi in exchange for Captain Sisko's desk on behalf of Nog, acting in the interests of Chief O'Brien of Deep Space Nine. In return the Musashi agreed to provide a phaser emitter to the USS Sentinel. (DS9: "Treachery, Faith, and the Great River")
