List of Collections
AO3 Collection for Art Yuletide on Tumblr.
A collection of fics where John Sheppard and Rodney McKay of Stargate Atlantis are a sentinel-guide pair. Either of them can be the sentinel or the guide - that's in the tags. The stories have to be complete, or have to come to a reasonable conclusion if labelled as WIPs. Only crossovers of Stargate-verse with The Sentinel are allowed, not complex multi-crossovers. McShep is the main pairing in the story or series and their relationship can be explicit, romantic, platonic bonded friends, an asexual bond, etc. - as long as they're the main pairing.
