I don't know, with the whole "Ascians are the Twelve" theory, I saw Lahabrea and Elidibus as Nald and Thal now, 12 and 13, but there being 14 doesn't make sense with it. We already have "The twelve are really thirteen" do we really need "The twelve are really fourteen?"

Maybe that's just wishful thinking on my part.

(I personally agree that Zodiark is probably a celestial body of some sort in the way that Hydaelyn is, be it the moon or an alternate, connected planet like IX or an AU).
