The rift station on Manaan was a secret Republic facility located on the edge of the Hrakert Rift with the purpose of harvesting raw kolto for the Republic. The station had built harvesting machinery on the edge of the rift which "woke" a massive firaxan shark, believed to be the Progneitor. This firaxan had seemingly called all of the firaxans in the area and drove the Selkath in the facility insane. These insane Selkath killed nearly the entire research team save a few who were lucky enough to survive.
