Lessu was one of the two capital cities on Ryloth. In the city, Ro Fenn's house and the Twi'lek Clan Council could be found. During the Clone Wars, Wat Tambor took control of the planet and positioned his headquarters in this capital city. Instead of a solid bridge, they installed a plasma bridge to control who came in and out of Lessu. It was freed from Separatist tyranny by the Republic Army and freedom fighter, Cham Syndulla.
