The Cult of Exar Kun was a Sith cult that was devoted to the worship of the Dark Lord of the Sith, Exar Kun. It was formed in 1 ABY, when a Corellia University expedition carried out an archaeological expedition to the Temple of Exar Kun on Yavin 4. They accidentally uncovered the catacombs beneath the temple, which reawakened the spirit of Exar Kun. The spirit enslaved them to it, making them into fanatical cultists that were devoted to its worship.
