Stars bound in shadows by
Illuviar reviews
The Stargate show implied that the timeline we saw in on screen was arguably the best. We outrigts saw many realities where various decisions and bad luck either doomed Earth, or saw it pay much higher price for its eventual ascension as a galactic power. This is a story about one of those realities where sheer luck and relying on a last minute resque are not wise decisions...

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.

Tony DiNozzo has just moved from Baltimore to D.C. when he makes a new friend who works for a classified program think tank-or something above his clearance level.
