Bot, a loner mediocre, was set on a scientific mission from his home planet Proxima-b to explore the virgin planet Earth and confirm its suitability to be inhabited by humans. Bound in secrecy to give the proximals an advantage over their eternal enemy, the Centaurians, Bot started the journey that would take him only about nine months in Earthlings calendar to reach that 4.2 light years distant planet, in an unprecedented attempt, or so his people thought.

He and his team discovered that this journey was made thousands of years before, but from the destination itself. The idea began as mere scientific research, but by the time it was put into action, it took another drift that resembled that of the Earthlings, a desperate attempt to save the last of the human race.

When his task was fulfilled, and he returned to Proxima-b, he decided to make that journey again, but this time with no return.
