I lost all my bookmarks a while back and couldn't remember the names of two specific fics (one of them has a sequel, but both fics are on ao3, so I don't need to find that sequel's title/author)

The first fic is a re-write of season 3 where Dean meets Castiel as the "dumb angel who got stuck in a ring of holy fire about a thousand years ago" in a cave while trying to run from a Wendigo. He agrees to let Castiel (who wears a toga) out if he heals Dean's broken legs. Reluctant friendship ensues, au season 3 with Cas occasionally helping out and the fic ends with Castiel dragging Dean out of hell 4 months post!death.

The 2nd fic is basically an au where Dean and Sam killed Lillith before all 66 seals were broken, so Michael is all like "fuck it" and sends angels down to bring about the apocalypse by killing all humans. Dean and Sam + practically all the human characters that were killed off in the show form a resistance and give Zachariah a headache, so he sends Castiel down to destroy said resistance and to find Gabriel, who they suspect is the reason why they can't find the humans. Castiel poorly pretends to be a human (it works) and eventually is won over with the power of hope by Dean's existance. The fic ends with the Castiel and Gabriel tearing out their Graces so that the continuously activated angel banishing sigil web they spread around the Earth doesn't send them back to Heaven.

Also neither fic actually has ~*Destiel*~ in it (the <3 kind anyway). Like the other characters imply it (it's really heavy in the second fic), but Dean and Cas don't really get past being INTENSE BFFs.

Thanks for the help! (I could not get lj-cut to work).
