I would've sided with Ernie and Grey Wolf. I didn't understand how Dranko could know that the cigar-smoke referred to Tapheon -- nor, for that matter, do I really get why Tapheon couldn't bear to have creatures from the Far Realms in his presence. It doesn't bother anyone else; why does it disturb a near-omnipotent demon?
That is a fabulous question. The likely answer is that what's inside Dranko isn't a Far Realms creature. It's some swollen, putrescent nugget of information too horrible to touch with his brain. Even brushing up against it erodes his sanity. The fact that it's too horrible for a demon lord is... troubling.
And how did I know? I dunno. But I knew it with utter certainty, the same way that I once realized beyond doubt that we were stuck in a city inside a bottle, even if we had no particular proof. I'd have felt pretty stupid if I was wrong, but I was literally willing to bet my character's life on it. Sometimes you have to have faith, in the story and the DM as much as in your character's convictions.
This was, I think, my favorite session (out of so many amazing games) in the entire campaign. Incredibly satisfying, and asking as many questions as it answered. It also brought up some really emotional discussion with the group at the meta-level as to what was appropriate and what wasn't. I value that even more than the game itself.
