The Trioculus affair was a conflict pitting the New Republic against the splinter faction of the Galactic Empire led by Trioculus, which took place in the year 5 ABY. Unbeknownst to both sides, the whole conflict had been orchestrated from afar by Darth Sidious, who wanted to keep the Republic away from his secret rebirth in the Deep Core of the galaxy, as well as to retrieve the right hand glove of Darth Vader to hasten his revival. By exciting Trioculus' crave for power, Sidious also led him on a quest for the Lost City of the Jedi and ancient Sith amulets.
