Looking for long/epic fics with Sam/Castiel, or Sam/Gabriel pairings. Fics with Sam/Anna would be cool too. Or Sam/otherAngel fics, if there are any out there. Also fics where Sam's powers are actually angelic or something like that, would be cool

Also looking for any stories that deal with the rings the Winchesters got when they cut them off the Horsemen they've taken out. Figured I'd see if anyone knew of any.

Any and all help would be appreciated.
Thanks
