Fortunately for House Haarlock, the swift elimination of the guards means that we have the element of surprise, and nearby was a lift granting access to the ship proper. Ascending the lift revealed another squad of Roh soldiers accompanied by a Tech-Adept who was tending to a labour engine. This indicates that the Roh garrison does not have full control of the ship, but have managed to establish a temporary power network to restore some key functions.
Quick reconnaissance showed that the squad had become somewhat laxed as a result of tedious labour and no movement, making it easy for our infiltrators to eliminate them quickly. Devil and Remy don the armour of the Roh soldiers to assess their strength and perhaps to draw a couple of soldiers away to further weaken their position. Nil posed as a prisoner, to help lure them into the ambush. Two soldiers are drawn back to the elevator where Gale and Li-Tal silently eliminate them using a sword and knife respectively.
With two guards eliminated, enough remained to be assassinated from range via simultaneous quick-shots. Unfortunately, the tech-adept was critically damaged (and beyond repair) by a not-so-well-placed shot to the head with Remy's firepike. Any information contained within his cranial cogitators was certainly lost along with any internal backups which may have been short-circuited.
The labour engine was secured safely, however, along with a substantial collection of unusual items. Among the items found were three more Haarlock-marked T-bills, no less than two archeotech weapon components, assorted medical supplies, and esoteric munitions. We also recovered one of the Roh encoding machines, and a codebook. This can grant us all of the access we need to steal the ship out from under the enemy.
During the brief combat, two soldiers ventured off and returned with alpha Legion traitor astartes. This revelation is most unfortunate, and reveals to us that Chaos is operating in the Barrows as well. The presence of two traitor legions in Haarlock endeavours is troubling, but must be dealt with regardless. We have beaten the Night Lords in combat, we can defeat the Alpha Legion and their cultists as well.
