Some more thoughts on Mamool Ja = Quetzacoatl?
In FFXI, Mamool Ja means "brethren of the shining scale" who could have shinier scales than Quetzalcoatl? The rivalry between Leviathan and Quetzacoatl from FFVIII would be reborn. Quetzalcoatl's special attack Thunderstorm would fit right in; out at the stormy seas.
