The Prospero system was a star system in the Beta Quadrant, located on the Federation-Klingon border.
Components
This system contained three inhabited planets, including Prospero Alpha.
History
During the Federation-Klingon War of 2256–57, Erica Ortegas was stationed near Prospero.
After the war, the Prospero system came under Starfleet jurisdiction. Ambassador Dak'Rah, a former Klingon general who defected to the Federation, was dispatched to negotiate an armistice between the three planets, which had been infighting for years. Following the successful conclusion of the talks in 2259, the USS Enterprise was assigned to transport Dak'Rah from Prospero to Starbase 12. (SNW: "Under the Cloak of War")
When the Venari Ral laid Omega-47 mines around the core of Federation space in 3196, this system was within the potential blast radius of one of the mines. (SA: "Rubincon")
Stellar cartography
In 3196, during the All-Worlds Day break, the location of Prospero was depicted on a star chart on the main viewscreen of the USS Athena. (SA: "Ko'Zeine")
Later that year, during the Omega-47 crisis, the location of Prospero was depicted on star charts and readouts used across several locations on the USS Athena to locate, monitor, and respond to the Omega-47 mines laid by the Venari Ral. (SA: "Rubincon")
