Sentinel Fusion story

[superk328.livejournal.com]

I am looking for a pacific sentinel fusion story. Sam and Dean, if I remember the story correctly, are sentinels. Cas and Gabriel are guides. Cas is Dean's guide and his spirit animal, again if I recall correctly, was a white wolf named Grace. Gabriel's spirit animal is a wolf named Loki. Gabriel is on ...trial I think, for killing his first guide. It turns in to this big thing, and Jim and Blair have to come back to work it out, which is a big deal. Also Dean is in a relationship with Cas and it's hinted that Gabriel and Sam will be in one, but I don't think the story is rated higher then PG-13 or what ever the equivalent grade the author decided to use.

And I think I might have just confused everyone. but any way if anybody knows what I'm talking about and could point me in the right direction I would be grateful.

Mod P.S. I couldn't find a fusion tag so I used the sentinel crossover tag. And I tossed in the genre:au tag as well. Hope that's ok
