Role in Plot
On route to transport prisoners, the Tartarus come across a lone Pelican out in space. The crew of the Tartarus allow it to land in there docking bay, where they discover the dropship's lone passenger: Felix. Felix quickly gains the crew's trust before he betrays and kills most of them, with Locus and the other space pirates raiding the cargo ship after Captain Mayers sounds the alarm. After the pirates kill all the crew members, they proceed to "recruit" the prisoners onboard the ship, while purging those who refuse to join their ranks out into deep space. One particular prisoner, Aiden Price, gives Felix and Locus valuable information about Carolina and Wash and leads them to another prisoner who has history with the Freelancers.
