Well - due to the last few days of conversations myself and
charlies_dragon have created a new AU, which also, due to its apparent length and possiblities, has its very own community
sg_pegasus
It's an AU set in Atlantis, that breaks from canon just after 'The Game' , through 'The Ark' will remain pretty much the same there will be differences, Sunday, however, will be very different, and from then on, it will be a true AU. Also, it takes an AU approach to SG-1 season 10, from 'The Quest' onwards, but that story will be left open for now, as the main focus is on the SGA team.
