This system had two nests of life, both a credible distance from each other; the vessel had probed them nearly two hours ago and now moved into sensor range of the asteroid base. Feeble communications were directed towards it, but it felt no need to respond, all would be purged, it mattered not if they didnt know the reason why.
It detected the engine trails of these human vessels, slightly different from the last it had encountered, but still much the same. The vessel doubted the difficulty of this minor purge. Again communications were aimed at it.
Unknown vessel this is Barrow Base, state your intentions. The vessel ignored them, ordering its semi autonomous fighters to attack the vessels that approached, it exulted in the death of life. As each enemy ship died in the cold void, the vessel heard their screams and rejoiced. Soon this sector would be cleaned and it would be able to return to another few millennia of sleep.
All vessels stow what you can and defend the perimeter. This puny life would try to defend what it had, but it would be to no avail, all would fall. After the destruction of more of these ships it was finally in range, powering up its full complement of weapons it turned them on the asteroid base. Within seconds the giant rock cracked and crumbled, opening its interior to the cold vacuum of space, yet more death, yet more exultation from the inhuman vessel. With the destruction of this base, the vessel turned its focus towards the other base in this system. Cutting its way back into the energies between dimensions it began its approach.
