Major character who has only appeared on 1 page in the entire OOTS saga

[Nazzo, the 102nd]

I didn't read the whole thread, so I don't know if someone already posted this guess. I'm thinking Tony.

We know it will be an important ally. And we also know Durkon has Planar Ally (or equivalent) as a spell. He mentions "calling the Deva" during the battle with Malack at Girard's Gate.

Also, Rich never said it would be a major character. And Tony has exactly one appearance. One page, one panel. It fits.

I'll bet... one quatloo on this one.


EDIT: Yes, Tony was already suggested. And here I was, thinking I was clever in a 29-page thread. Silly me.
