Battle of Kemplex Nine

In 3996 BBY, Jedi and Sith forces fought an engagement at the Kemplex Nine space station that proved to be one of the major turning-points of the Great Sith War. The Sith Lord Ulic Qel-Droma originally conceived of a plan to attack the Republic base at Kemplex Nine as a feint, in order to draw forces away in preparation for the upcoming attack on Coruscant. Following the capture of Qel-Droma during that battle, Aleema Keto again proposed the idea to attack Kemplex Nine and capture the jump-station there. Events, however, conspired against Keto and her plans for herself and Mandalore the Indomitable to attack the space station; Qel-Droma was rescued from Coruscant by the Dark Lord of the Sith Exar Kun and Mandalore. Following his rescue, Qel-Droma decided that Keto and Crado would lead an attack on Kemplex Nine in preparation for an attack on Ossus. Through the use of Sith magic, Keto unwittingly set off a chain reaction of explosions in the Cron Cluster, which destroyed all forces present, both Sith and Jedi. The resulting supernova also sent out a massive wave of destruction from its source, which eventually devastated the Jedi planet of Ossus.
