Huh. Yeah, that's some pretty obscure connections, but seems like it's probably correct... I bet Wyatt must have run that module to be that familiar with it.
If the October book truly is a Dragon book (and I think the consensus is that it probably is) then it would make sense for this to be explained a bit more there.
I am curious what the format of the book will be, as it seems like it will combine monsters, subclasses, races and lore into one book but also not be a new setting. Unless it really is Dragonlance, but I doubt that.
