Yeah. Frankly its been a homage to Moby since ARR. There is a Limsa restaurant called the Bismarck about a legendary white whale from Sea Wolf legend.

The thing with Bismarck I really am interested in is how a see Wolf Legend turned into the god of the Vanu Vanu. After all the Vanu Vanu legend says that the White once swam in the seas until the other whales turned on him and he was rescued by some divinity and given the ability to swim in the Sea of Clouds. Seeing the Vanu Vanu also repressed by others he rescued them and carried them into the skies.

So the question is, what was the original Bismarck. An actual whale given the ability to fly by some magic as the legend says? Something the Vanu Vanu and the Sea Wolves mistook for a whale?
