Rhommamool / Legends Rhommamool was an impoverished mining world in the Expansion Region , along the Corellian Run . It was in the same system as Osarian . Geography . Rhommamool was an inhospitable desert world with red sands . Life on the planet was tough for its inhabitants with even basic essentials like water lacking . However , Rhommamool had large reserves of valuable minerals which would be exploited by the government of neighboring Osarian . Rhommamool orbited the wealthier Osarian with the latter using the former as a dumping ground for convicted criminals and a mining colony . The two planets orbited each other and were brought together within a million kilometers of each other every ten years , usually resulting in a flare - up of hostilities between the two . The planetary capital was at Redhaven which contained the planetary spaceport and the Square of Hopeful Redemption which was built from the ruins of the Portmaster ' s Pavilion following an uprising around 25 ABY . History . Colonization . Rhommamool was settled by convicted criminals brought in by the Osarians as de facto slave labor for the planet ' s mines . Much of the profit from these mines went to fuel the lifestyle of the richer Osarians . Although the worlds shared a single government , it was based on Osarian and dominated by Osarians . The situation largely stayed under control due to the fact that neither planet had extensive space forces . However , every ten years their orbits would bring the worlds within a million kilometers of each other , close enough for each planet ' s ground - based nuclear missiles to hit each other if launched . At those times of closest contact , the conflict would flare up . Until the close encounter of 25 ABY , the worlds managed to hold off attacking one another . Jedi Civil War . During the Jedi Civil War , the planet was the location of a battle between the Sith Empire and the Galactic Republic . The Republic won the battle . Clone Wars . Rhommamool was loyal to the Galactic Republic during the Clone Wars . Imperial era . As of 2 BBY , a small Imperial presence was established around Rhommamool . New Republic era . Prior to 25 ABY , Nom Anor was dispatched by the Yuuzhan Vong to the planet to stir up dissent between the poorer Rhommamoolians and their richer Osarian cousins . Using a disguise , Nom Anor drew disciples to his cause by preaching hatred towards all forms of technology including droids and landspeeders , the hated Osarians and the New Republic . These disciples became known as the Red Knights of Life due to their red cloaks . In 13 ABY , Emissary Xbrr - Zinngogg of Rhommamool went to Coruscant in order to warn the New Republic Ruling Council about Nom Anor ' s attempts of destabilization in the Osarian system . Chief of State Leia Organa Solo refused to intervene , considering this situation as a local matter . In 25 ABY , the Red Knights of Life launched a planetary uprising which captured the capital Redhaven where a provisional independent senate was installed to rule the planet . During this period , the Red Knights of Life launched a violent crusade against mechanical technology and presumably Osarian collaborators as well . Their actions ranged from attacking civilians simply for using a landspeeder to rounding up all the droids they could find and dumping them at the Square of Hopeful Redemption in Redhaven . There , they would throw droids into a large pit and bombard them with rocks until they were nothing but a pile of metal , one of whom was C - 9PO . During the Osarian - Rhommamool conflict , Nom Anor ordered a missile strike against the Osarian capital of Osa - Prime when the orbits of both planets were at their closest , destroying the city and causing the political conflict to become a war . More missiles would be fired by Rhommamool , destroying more Osarian cities . Large red thermonuclear blast clouds also appeared over the planet , presumably causing harm to millions of Osarians . During the Yuuzhan Vong War , the Iron Knights fought the Red Knights of Life on the planet . The world was eventually conquered and held by the invaders . Behind the scenes . In " " , " Rhommamool " was misspelled as " Rhommammoo " .
