So... I love how you can fly in the game now, I love the flying theme that the Griffon has... but it shares it with both Midgardsormr and the Manacutter... which annoys me... the mounts have traditionally had pretty different themes.... so my thought was that Square should use one of their old songs for the Manacutter... Wings, from Xenogears.
