The Skirmish at the Hidden Jedi Temple occurred in 137 ABY during the time of the Second Imperial Civil War. In this event, a team of Imperial Knights engaged in combat with Jedi Knights who belonged to the New Jedi Order at their Hidden Temple.
After seeing the massacre on Mon Calamari and an Imperial patrol almost causing the death of his relatives, Cade came to the conclusion that assassinating Darth Krayt was the singular solution to resolve the conflict and achieve his own isolation from the galaxy.
When Cade got to the Temple, he was taken aback to find Imperial Knights, Marasiah Fel, Antares Draco, together with Ganner Krieg. Immediately, he and Shado Vao began fighting Draco and Krieg. He concluded the battle by using the Force pushing ability on the two knights.
