The Dark Assembly has always been an asset of Darth Marr’s military operations in defense of the Empire. When his fleet went into wild space to find the former Emperor, The Leviathan, a ship fitted with Isotope 5 and granted to the Dark Assembly, was a rear guard left near the border of wild space. With the destruction of Marr’s fleet including his flagship, Lord Hael was ordered back to Dromund Kaas to warn the Dark Council that they had found the Emperor and that the fleet he commanded was destroyed.
After Darth Marr's capture, the Dark Assembly shifted focus. At first we observed the Empire, and the Dark Council to see how they would react in his absence. After the Death of Marr and as the fighting began we participated in the war against Zakuul, fighting numerous battles, but we had a secondary objective, we were scouting places for our organization to go should the need arise. We went to a number of uninhabited planets and some that were only colony worlds in search of a refuge to regroup from.
When Darth Acina bent the knee to The Eternal Empire, we made for our new base of operations. When it became apparent to Darth Acina and Zakuul that the forces that once belonged to Darth Marr would not cooperate with the treaty, a warrant was issued for those that remained loyal to the idealism that Marr had set forth prior to his death.
Dark Assembly is still very much part of the Empire. Being known subordinates of Darth Marr, Darth Acina and Lord Hael thought they were the right outfit to be exiled and search for means to defeat The Eternal Empire. In all outward appearances, The Dark Assembly is a traitorous organization working against the Empire's treaty with Zakuul. They operate in the shadows as the leading members have warrants and bounties out for their capture and execution.
They spend their time building intel on Zakuul, stockpiling the Empire most powerful weapns by means of raiding Weapon's caches and resouse depots. They operate from Ziost space and have numerous bunkers that house the stockpiles they have builtup over the past 5 years.
Another focus of the organization is to collect as much information on Zakuul as possible as well as stealing technology and attempting to integrate it with the Empire's in order to build an effective weapon against The Eternal Empire. Lord Hael also ordered a team in place to spread propoganda to incite instability in the Zakuul Empire.
