COMPLETED! A Babylon5 SG-1 crossover. Daniel gets a mysterious message from a distant place and time, with a very unusual Gate address. I last posted to this one in 2006 but then life got in the way. This year, I decided to revisit and complete it, giving the whole thing a rewrite. If you read the original, I'm sorry for the 18 year wait but I hope you enjoy the finished story!

Stumbling through Godhood by
freeraynman reviews
If you could travel through alternate realities what would you do? Become a God and rule or chillback and go with the flow? Inspired heavily by 'Cruel To be Kind', '12 Steps To Omnipotence', 'Rise of an Empire' and a million and one other fanfics. If you see stuff and think that it's similar to another fanfic. it's probably because we read the same story and I liked that idea.
