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.
