Show: SGA
Rec Category: AU - specifically, cut off from Earth.
Characters: John Sheppard, Rodney McKay and many others, as below.
Categories: Het. Note that Dossier calls it Gen, and of course there are many views of what constitutes "Gen". I'll just say that both Rodney and John are in established relationships with OFCs by the end of the story, so I don't think it's Gen, myself, and readers who need John and Rodney to be together should be aware of the other, het pairings.
Warnings: There are character deaths, even of main canon characters, but not John or Rodney.

Why This Must Be Read: At 145,393 words, this is a novel-length feat of extraordinary world-building. It starts with the theme I'm reccing this month - in that the story diverges from canon during "The Intruder" (S2E2) when John and Rodney fail to eradicate the Wraith computer virus in the rogue dart, and the Daedalus crashes on a hitherto unknown planet with no Gate and is stranded there. So this isn't the whole expedition being cut off, just everyone who was on the Daedalus, or who made it through the crash, anyway. The story is a detailed account of their survival and exploration of the new planet and the culture they find there, how they acculturate - or don't - and how John, Rodney and many others make it their home.
If you like Sheppard-centric stories this is for you, although Rodney has an important role as well, as do others who happened to be on that Daedalus trip, like Elizabeth, Lorne, Carson and Caldwell. The flavour is rather Islamic, from the style of names and words in the local language. But there's also a Dune-like feel, as the place where they crash is largely desert, and John develops special abilities linked to his Ancient heritage and becomes the "Chosen One", tied to the planet and its people. Despite this, the characterisations are complex and well done, and John changes a lot across the years the story covers, or rather, he's changed by the world, Dominat, and its people. The big strength of this story is the extraordinarily detailed world-building of the planet's culture and people, which is managed naturally and without noticeable info-dumps. I found it a gripping and fascinating read. It's an older fic, archived at the AO3 well after initially being posted, so it has few comments or kudos there. It deserves a lot more.
Note that it was reccd 12 years ago by
sholio in the John Sheppard category, so
here's a link to sholio's rec, as there's more and better-expressed praise for this story there. Just don't use the defunct link there - use the AO3 one above. The AO3 fic is titled "Chapter One" but it's the whole story in 24 chapters. There's a second in the series, but it's very different, is Elizabeth-focused, and is about grief and the assassination of her daughter, so be warned.
