Rozzum

The Rozzum were a species of sentient aliens who came from another dimension than that of the known universe. They had ties to the Order of the Terrible Glare, a group of dissident Jedi Knights formed during the Pius Dea Crusades. In ancient times, several Rozzum were stranded on PL-40112-CE-021105, a planet of the Wild Space. Some time later, during the Empire's reign, Imperial surveyors encountered that group of Rozzum after having inadvertently awakened them. The Imperials allied with the local people to fight the monsters off, which left only two survivors. During the Galactic Civil War, the young Luke Skywalker encountered Rozzum on Garn, where he had been lured by Rur, the last High Shaman of the Terrible Glare.
