White Masks and Sacrifices...
I only remember one particular scene in this fic, so I would be incredibly amazed and thankful if someone could remember its title!
It's a Remus/Sirius fic (of course) featuring Regulus prominently. Regulus is a redeemed Death Eater who is now spying for the Order, but (I think, details are a bit hazy now) he's pretty sure he's going to get killed soon. There is a battle where Bella casts Avada Kedavra at Sirius, but Regulus leaps in the way (this is while he's dressed in Death Eater garb) and takes the blow for Sirius, who lifts his white mask and sees the lifeless eyes of his brother. He apparates away from the scene with his brother's body to James's flat, where James, Remus, and Lily (and maybe Peter?) follow shortly thereafter. Sirius tells the story of how he and his brother used to play in this one meadow before they got sorted into different houses, and goes there to bury him. Remus and Sirius dig a spot for a grave together. Sirius carves a headstone and says a few words to his brother, alone, before apparating back to James's flat. (I remember this was rather reminiscent of the scene with Dobby in DH.)
Sorry for the lack of detail; this was only one scene in the entire story, but it just about killed me when I read it because Sirius was so devastated. I'd love to find this fic again, and would also welcome any recs involving Regulus as a major character :)
