Valnoos was a world in the Chiloon Rift. In 45 ABY, it was home to several casinos which were attended by miners in the rift, including Tharston Kharl. The most notable of the casinos on Valnoos was the Blue Star, which was the site of an assassination attempt on the lives of Han Solo and Luke Skywalker by the Columi brothers, Craitheus and Marvid Qreph.
