Following the Federation - Klingon war, Prospero Alpha engaged in years of infighting with the other two populated planets in its star system. The Prospero system came under Federation jurisdiction. They dispatched Ambassador Dak'Rah, a Klingon, to negotiate an armistice between the three planets. Dak'Rah found the delegates Prospero stubborn, perticularly those from Prospero Alpha. He described obtaining agreement as being akin to "getting a Tellarite to give a compliment". The cease-fire was finally signed in 2259, after which the USS Enterprise was given the task of transferring Dak'Rah to Starbase 12. [1]
