The in-universe fiction and lore, as opposed to game rules.
Sorry, I wasn't very clear. I do know what fluff is. What I meant was, Luciora said that he converted a Crockett to a Black Watch,
per the fluff, and I wondered what he meant by that. Rereading it now, I realize that I mistook Black Watch for a Black Knight, especially since he's using a Black Knight head. I thought that he was trying to say that someone, somewhere in the Lore had converted a Crockett to a Black Knight. But now I think that he was saying that he did some conversion work to make the Crockett a member of the Black Watch. Do I have the right of it now?
