The Selkath people are forced to return to the sea[1]
The devastation of the planetManaan was an act carried out by the Sith Empire during the Great Galactic War, sometime between 3,681 BBY and 3,653 BBY. After centuries of hiding in sectors of space unexplored by the Galactic Republic, the Sith returned to the known galaxy and initiated their crusade against the Republic's member worlds and other planets. In their campaign for dominance, the Empire traveled to the water world of Manaan, a planet known for its staunch devotion to neutrality during periods of war. The Sith refused to accept the native Selkath's tradition of impartiality and so destroyed all of the free-floating surface structures on the planet.
During the war, the Empire also came into conflict with fiercely independent societies, such as the Selkath of Manaan. Manaan was a water-covered planet with a long avowed neutrality during instances of galactic conflict[1]—during the Jedi Civil War of the Old Sith Wars era, the native Selkath managed to maintain their impartiality and broker their kolto healing agent to both the Republic and Darth Malak's Sith Empire.[5] However, their political stance did not appease the reconstituted Empire, and sometime before the end of the Great Galactic War, the crusading Sith decided to attack the planet.[1]
The Sith assault on Manaan targeted the water world's free-floating surface structures, all of which were destroyed. The loss of their above-water dwellings forced the Selkath to flee back to the sea in a mass exodus.[1]
Manaan was just one of numerous planets that suffered heavily during the twenty-eight-year-long Great Galactic War. The Sith invasion saw the abuse and destruction of several star systems, while many others fell to armed engagements between the Empire and the Republic.[1] The conflict ended in 3,653 BBY with the signing of the Treaty of Coruscant,[6] and by the reign of the Galactic Empire in 0 BBY, at least one floating structure—Ahto City—had been rebuilt.[7]
The devastation of Manaan was first mentioned on the official website for the LucasArtsvideo game, Star Wars: The Old Republic. The information could be found on "The Setting," a webpage intended to provide background on the game's historical period. Since its establishment in 2008, The Old Republic's website has gone through a number of changes, resulting in the removal of some of the text that was originally located there. "The Setting" was updated mid-2011, and the information on Manaan was removed.[1]
