Attenuation: Letters From The Man In The Moon
We sent him to build a worlds for us to have a future on. By the time he got there, we had completely forgotten about him. These are the letters from the world maker, The Man In The Moon.
Over time, he goes from trying to remind us how he got there, to trying just to keep us alive. It isn't easy, when you're broadcasting from a moon around another world, around another star.
