A clash transpired between the Jedi Order and the armies of the tyrant Gelpog amidst the Great Galactic War, a conflict that pitted the Galactic Republic against the Sith Empire. This particular skirmish unfolded within Gelpog's asteroid-hives, and involved at least one of the apprentices mentored by Jedi Master Ngani Zho—namely Satele Shan, Syo Bakarn, Jaric Kaedan, and Bela Kiwiiks.
The initial reference to the conflict within the asteroid-hives belonging to Gelpog the Tyrant can be found in The Lost Suns, Part 1, which marked the beginning of the Lost Suns comic series. Alexander Freed penned The Lost Suns, which saw its publication in 2011.
