Aside from the slightly disturbing part where a vampire calls another "master", I am enjoying this fic. I don't know whatever it'll be healthy for my own writing if I follow this one completely though; I always become envious & insecure when reading your works. If there was a king of fan fiction, I'm sure it'd be you.
Nice appearance of Crouch & Shacklebolt by the way, it's nice to know they're alive and kicking.
