After reading a number of Friday Fictioneers using this prompt to come up with stories of aliens (why didn’t I think of that in the first place?) I’ve written another 100 word story.
The End Is Nigh
Insignificant. It fell to earth late one dark December night unnoticed, undetected. Here, among these barren, wind swept rocks, it has lain dormant for hundreds of years, waiting for its instructions. They finally arrived early this morning. Beamed earthwards from a star, many light years away. From a race that has been watching us and waiting, knowing this day would come. The emerging tentacle will grow stronger each day as it bores its way through the earths crust down to the very core of this doomed planet. By the time we realise what is happening, it will be too late.
