Now, I know what the fic is called. It's 'Evernight' and the author had written like 50 something chapters and a few one-shots for a Sirius/OMC (Julian Shadowclaw?) pairing that was in the story.
It was about a friend of Severus's that was a magical creature choosing Harry to become a morion. He becomes really beautiful, has to dim that beauty and Sev is his mate. Julian (?) turns Sev and Harry is pregnant. Draco and the female friend of Sev's (I'm mental-blanking on her name) run off together because Lucius had tried to enslave her and her father hates all Malfoy's.
I know the author (I cannot remember their name) moved it to a different site and I was wondering if anyone knew which site, or had the url, because I cannot find the story on here. I really want to find it because it was one of my favorite stories.
I'd appreciate any help in finding this fic.
