A morning like any other, or so they thought.
We were present, beyond their knowledge. Our eyes had been upon this place, the place of our sister, the place they now called theirs for longer than they existed. Their time was a mere blink in our scale of time.
We had watched, waited, hoped. It was now the time of correction and renewal. Our sister had cried out to us, begged us to return and act to save her.
What have they done to our fair sister? Ravaged and plundered and ripped her and bit her. Stuck her with knives in the side of the dawn and tied her with fences and dragged her down.
We heard a very gentle sound with our ears from far away. The sound of our sister begging for mercy and relief. We had neglected her for too long. But now we were at her side. They did not know. They would not know. Only she would know until after we had begun.
The brilliant flashes and thunderous roars from above had not phased them, nor had the blinding white and blowing of bitter cold. Rising waters had only driven them away temporarily, soon to return to their evil. That had not learned. She had tried her best with her limited abilities weakened by their evil. We would correct that and redeem her soul to help her heal and regain her once mighty strength, returning her to her former glory of brilliant, sparkling blue.
But first, they had to go.
Our fair sister gave her signal, and we began.
A mass of targets disappeared in the blink of their eye without a trace. Our devices did not make mistakes. We gave no warning. Millions of the parasites simply ceased to exist.
Our message would now be sent. This was the first they knew of us, after the mass obliteration. It wasn't necessary to have them understand why. It was necessary for others to understand.
