on the capital world of Coruscant

around 3643 BBY during the Cold War. After careful analysis of the Imperial military, Senator Barc began to believe that the use of slavery could be the key to beating the Sith and returning the Republic to dominance. Because slavery was once an accepted practice in the Republic and it continued with great effectiveness on many Outer Rim worlds, he planned to advocate for the repeal of the anti-slavery law in the future, but first he wanted to prove his point. Purchasing an entire shipment of Rylothian

slave collars, Barc intended to use the collars ito bolster the Republic's military and economy efficiency.
As Barc's shipment arrived on Coruscant members of the Migrant Merchants' Guild

hijacked the shipment. Displeased by the hijacking, Senator Barc ordered the Coruscant Security Force

to locate the shipment and return it to his office. When Captain Denal-Zon

tasked a group of Republic operatives

to track down the shipment and return it. While the operatives did collect the slave collars, Captain Denal-Zon caught up to them and was able to convince them to bring the illegal chips to him for destruction, and that was exactly what the operatives have done.
Although Bark was greatly dissatisfied with both the operatives and Captain Denal-Zon, he was unable to retaliate or even officially raise the issue with CSF because the chips were illegal and Denal-Zon registered the disposal in a perfectly legal way.
