Elder Primal?

[Belhi]

To further support the theory, Bismarck is an old legend told among the Roegadyn, and since the Vanu Vanu have been up in the Sea of Clouds at least as far back as the Allagans, we can reason it out that they have likely worshiped the White for that long.

True but there legends don't really match with the Bismarck we fight. Their legends describe a benevolent creature.

Ravana's dialog in the MSQ seems to suggest he is new too. He seems to describe himself as the Gnath's desires made manifest.

Of course Im bias cause I'm still like the theory that the original Bismarck was a Allagan warship capable of submersing to visit aquatic Allagan sites such as Seal Rock.
