7 years ago to the day is when we first discovered them. Working like panicked ants they covered the entire surface of the asteroid. It was momentous for our team to discover evidence of extra-terrestrial activity for the first time, even if they were just machines from a civilization long dead.

It wasn’t long before we could determine their function. We knew that they were dangerous, but we greatly underestimated the ferocity of their directive.

Within 6 years time, they had completely stripped the asteroid until it was a hollow skeleton filled with millions of tiny robots.

As they descended upon the Earth they blacked out the sky and the sound of their mechanical whirring was deafening. Within three days, 99% of life on Earth was extinct.

I watched the grisly scenario unfold from the station knowing that there was nothing anyone could do. Humanity was crushed by a mechanical demon, incapable of remorse or fear.

Floating above the brown waste that was once Earth, I am humanities final breath.
