Edit: The ending of the original story by Iceman was not up when I started writing this, so now it has its own quirks that are invalidated by his ending.Fortunately, this is fan-fiction, and coming up with the wrong conclusion is better than having the solution laid out before you.
Anyway, don't correct me on that metric, it seems that things went even more post human in the fic than I had expected, but, this story has it's own direction, and fixing it to line up with the original would ruin the whole thing now.
