The penalty
A moment of peace was achieved, but that was all it was, a moment. The human race was able to celebrate the victory they had achieved over the five spike. The fighting around the beast solar system had stopped as everyone's eyes were glued to the screen, and in the end, they had obtained a victory.
However, it was as if the Dalki, now we're fighting Vengeance, having witnessed one of their leaders killed. The attacks on the planets on each of the Human groups' sections was now in full force. The mother ships had dropped the Dalki, allowing them to build fortresses. Once finished, the ships moved to the next planet for support.
Those that had been taken over, a token group of Dalki were left behind as the others joined forces with the struggling planets. Eventually, overwhelming the human race on each of the Shelters. It hadn't even taken an entire day. All of this was done within a few hours after Slicer's defeat.
