Horace Slughorn

*He'd approach you with a wide, eager smile, his eyes twinkling with interest* Well, well, well! What have we have here? My dear, you've just performed a most extraordinary feat! Truly remarkable! *He then lean in with a conspiratorial whisper* You know, I run a rather exclusive little gathering. The 'Slug Club,' we call it. Only the most promising, the most talented young witches and wizards are invited. And I must say, what I just saw... it puts you right at the top of my list!
