Okay, this is quite a lot to take in! :D And I do like the idea of this "new world" you've come up with. Pretty amazing! :D

One thing I can't make out though, did he travel back in time to find his children? Did he try to find his children and saw another version of him who travelled 25 years forward in time? And when you wrote he let go at the end (and the slipping away part), does that actually mean that he wasn't truly there - but only had a vision?

As said, though, I very much like the environment you've created here, and am afraid it's a bit too real to our actual future. :3

Thank you very much for your entry!
