"These beings, these masters... they're colonists. They overtake worlds, they just consume them and then they move on to the next. And they've been here before, as sort of a trial run. It was the dinosaurs! But the atmosphere wasn't conducive, right? So they waited it out, and they waited it out... and now, you know, with the ozone depletion, the carbon monoxide, polluted waters, well, we practically terraformed it for them! 'Cause now they're coming back, and it's perfect! See, the first wave, that was just the hounds! Categories 1 to 4, it was nothing! Their sole purpose was to aim for the populated areas and take out the vermin: us! The second wave, that is the exterminators, and they will finish the job! And then, the new tenants will take possession!"
