(the story is loosely based on Mass Effect 2)

Aria T'loak, ruler of the Omega space station, was enjoying yet another night at the Afterlife club when her assistant, Bray, approached her and nervously handed a datapad. He found some disturbing news through their spy networks. After reading it Aria became furious! Collectors were secretly building their base at the top of Omega's surface in its caverns and were sabotaging some of Aria's smuggling traffic – something she had previously thought was the work of other rival pirate gangs. Collectors find the station to be very suitable for their next invasion and converting it to a new Hive, which already began since Omega has a lot of salvagable tech, metals, element zero and it's strategically close to Omega Relay.
Aria ordered Bray to find her best engineers among the mercenaries who worked for her. A few moments later they found two talented Vorcha engineers. They made Aria new tech armor based on some illegal designs from black markets, although the armor wasn't perfect but it will last for at least one mission which was enough. The Vorcha also found themselves hired to push the Collectors back and to use their skills to repair Omega after, but they need to be very careful about damaging the infrastructure any further. Aria yelled in rage: "Those damned Collectors! Sneaking around on my turf! Argh! They will know soon enough that should not f* with Omega! Or better yet, this time I will tell them that myself: "DON'T F* WITH ARIA!"
