Namek
A series of out-of-this-universe beacons, black-and-white, as well as a few other spooky-looking droneships were located within the system - far away from planets. They had picked up transmissions from the slave/illegal planet, but after some talking and a little bit of threatening from the boss, they agreed to not broadcast the location. In fact, from what was gathered, it seemed they could have been possible trade partners, with their curiosity of the different life forms of slaves, they could potentially sell many different kinds to them for the drones to study...
That is, up until a MkIV Long-Range Psionic Specialist scout android that was stationed on one of the Beacons picked up on a thought:
Namek You may take this universe, my boss will take dimensions...”
This alarmed the android, and through its mind-link with the other androids in the Beacon, the entire crew knew at the same time the MkIV Scout did. Nothing could stop a rift-transmission instantaneously being sent to the entire Explorer-Class of the Dimensional Collective, who in turn transmitted it to the rest of the Collective. Explorer-Class Communications equipment are more advanced than those of the other classes in the DC.
They knew what was coming next. Despite the very low chance of survival, multiple Rift-Portals appear for the armada of Droneships to fly through, and they attempt to do just that. The Beacons, dedicating most of their power into the Rift Portals first, cannot activate their Rift-Drives at this time.
