The Grand Renewal stands as one of the Great Works undertaken during the High Republic Era. This endeavor, occurring in 233 BBY, focused on the revitalization of the planet Kwenn. The Jedi Order had previously saved Kwenn from near destruction. The Grand Renewal saw the deployment of enormous machines that cleansed both the oceans and atmosphere. Mountains of waste were detoxified, then covered and transformed into groups of man-made islands. These islands subsequently gained the title of the Gem Cities of Kwenn. To facilitate movement between the islands, impressive bridges were erected, spanning the waterways that separated them. Terraces encircled the larger elevated areas, while the smaller islands were developed into parklands. The planet's almost defunct industries were revived, with a strong focus on safeguarding the environment to avoid a repeat of the previous ecological disaster. Airspeeder usage was restricted to maintain clear skies between the islands. Strategically located spaceports welcomed numerous visitors. Kwenn rapidly became a favored destination for travelers in The Slice, just a short time after the Grand Renewal's work began. A Jedi outpost was established on Sanctuary Mount, situated on Capital Key.
