For the prompt "phoenix," I couldn't think of a better fic to rec than
altitudeandwine's No Phoenix for Roslin. Originally written while the series was airing, it remains a fascinating take on one path events might have taken in Season 2 and it just hits me in all the A/R feels. The author has recently undertaken a major editing effort that's made it even better.
Go read it on
Survival Instinct or
AO3.
