Robot

 55555's:

The day was cloudy, and red flashes lit the clouds on the horizon. It would be here soon. A man with a laser spike stood beside a small spacecraft, carving these words into a metal obelisk. He looked up from his work to check the horizon once or twice, and returned to his task calmer, and writing more clearly.

"The scientists, the wizards of machinery, electronics, physics, and the other answers to the riddles of reality, created this. On their shoulders lie the burden of this event, it is their hands that this blood stains. The only possible excuse for these sad men is that of total lack of understanding. Perhaps they din not know what, or the scale of what they were creating. So many lives have been lost.

"The Robot is impervious to all weaponry that we have turned against it. They thought the larger nnuke would work, but it marched out of the destruction, thinking only that we had done its job for it, leveling the city and decimating its inhabitants.

"I see the future of mankind clearly before me. Our home guarded against us by a device of our own making, forced to live in the airless void of space and the barren rocks of Luna and Mars, raiding our home world for air or materials when our need is greater than the threat of death. We will return like a master fallen to robbing his old estate, slinking into the place he once owned, stealing what had once been his.

"If you see this marker know well that it searches for you and desires your death."

The man looked once more the the western horizon, and leapt into his vessel, rapidly pulling levers and snapping switches. The cables detached and the craft soared spaceward.

A strange silhouette reared to the west, but his life was safe this day.
