This ship has gotten me out of situations that any other ship would have been destroyed in. Seen a lot of action, from the Clone Wars to the New Separatist Crisis. Best ship in the galaxy right here.
—Unit 1337, captain of the Prosperous
The Prosperous was a Providence-class battleship that was originally created by the Confederacy of Independent Systems for use by the Separatist Navy during the Clone Wars, but came under control of Gizor Dellso and later Unit 1337. It was modified by both the Geonosian engineer and the droid, but looks similar to the standard Providence-class battleships.
It seen action in the Clone Wars, during the Battle of Coruscant. During the battle it was captured by Republic Marines and was taken into custody of the Galactic Republic. When the Galactic Empire came to power and replaced the Republic, the Geonosian engineer Gizor Dellso acquired the ship for his navy by unknown means. It was put under command of the veteran battle droid Unit 1337, a droid marine, and was used by the Separatist remnants of Gizor Dellso over Mustafar.
When Gizor Dellso's forces were defeated, it fell into the hands of the Empire, who gave it to the then-Imperial Unit 1337 to use in his campaigns against the Rebel Alliance. It seen action over Yavin IV and Hoth, but was stationed over Sochi in the Mid Rim during the Battle of Endor. It later fell into control of the Separatist Alliance when captain 1337 defected to them. It seen much service under the Alliance during the New Separatist Crisis and later was one of the most prestigious vessels in the Separatist Astrofleet.
