Relevant quotes from Dusty:
"I don't think I ever talked to Phil about Warhammer. I tried to get him interested in RPGs, but he had a level of contempt for them I usually only see in people who insist that their Magic collection being more expensive than their house doesn't mean they're a 'gamer.' I doubt he knows what a d20 is, much less the Ruinous Powers. [...] Mostly, I seem to recall he got pissy whenever I suggested we do anything that wasn't originally his idea, be it just the two of us, or the anime club, or whatever. [...] Like I said to Michael, Phil is not a bastard child of Slaanesh. With Slaanesh, you want to fuck the abomination, but you feel dirty about it. With Phil, you don't want to fuck the abomination, and you feel dirty anyway."
[Here the conversation wandered a bit, and then I mentioned other aspects of the thread]
"I know we never talked about paganism, and if he's going around pretending to be Wiccan, it's giving me new appreciation for the notion of burning witches at the stake. I certainly never taught him anything about it. [...] Satanist? No, he never said anything. Given my history, I'd've cut him off then and there, you know that. [...] He never let me talk about books; that would be something he didn't initiate, so it was verboten. So no, I don't think we ever discussed Elric."
