Whoa whoa whoa. Hold the phone. The Nymians are the Tonberries now. In XI, Diabolos tells you that the Tonberries are the former Kuluu who changed after he freed them from The Emptiness. Dare I say it... We now have something as to what happened to the Nymians. This also begins to link Diabolos to the Primals, ever so loosely. Though he's no where close to them, Diabolos could be the Primal of the Tonberries.
