- "...to my fellow grand moffs, and to the grand admirals, other officers, stormtroopers, bounty hunters, slavelords, and slaves, I bid you all Dark Greetings!"
- ―Bertroff Hissa at the Committee's opening
Seceding from the weakened Imperial Ruling Council, it claimed authority over the whole of the Empire, including the Rebel Alliance. Bertroff Hissa was its organizer and unspoken leader, and moffs Vilim Disra, Dunhausen, Muzzer, and Thistleborn were senior members of its Council. The face of its operations, Trioculus, was a weak figurehead championed as the mutant son of the late Emperor, and was ostensibly the committee's head. They were stationed aboard the Moffship.
The committee organized the assassination of Grand Admiral Rufaan Tigellinus, and met on Kessel to advance Trioculus's claim to the Imperial throne. After the deaths of its head and figurehead, the remaining members of the committee presumably deferred their power to the Imperial Ruling Council, and all future plans to subdue the Alliance by the said committee were discontinued.
