So do I, which is why I am of the opinion that the Reveal's narrative punch won't be based on the species (which, when you think about it, is the least important part of what makes MitD himself), but because of the personal growth that, I'm guessing, will come to fruition in that moment. Narratively speaking, MitD completing his development from Stooge of Evil to Friend of Ochul is far more likely to deliver the kind of emotional gutpunch one has come to expect from the Giant.
But yes, of course I might be wrong, and it will turn out to be something well known (you'd be surprised about Tarrasque, btw - being a French monster, a lot of non-D&D people seem to be aware of it. My dad, for example, who has never in his life held a dice with more or fewer than 6 sides, was perfectly aware of what a Tarrasque looks like... although of course he did not know about, say, the anti-magic properties of its shell, or the need to Wish it dead), but if that is the case, I'd expect it's in the first page.
And that's the thing. For something well known to be kept a secret that long, a lot of the clues have to be red herrings, or have to be completely useless - so generic they never actually painted enough of the picture we could narrow it down. Which in many ways, feels like cheating - pretending that you will be doing an honest game, and then carefully ensuring that no-one can win it. That really doesn't strike me as something Rich would do, but plenty of people have disagreed (although they never have agreed on which clues are red herrings... significant bias has been involved).
I am very glad that is the case - that is what I intended this thread for when I took over. Thank you for your kind words.
