Indeed, I also made an error in my original post, it's Pumice not Plumes that you needed to Summon Ark in 9. with that out of the way. I can (kind-of) see the Manacutter either being converted or a new model based off of Ark, Granted I don't know if any of the Iron works crew saw Ark during the fight, so It may end up being a mogstation Companion(seeing as I have no idea how that would be integrated into the story at all). At any rate I would Agree that making mounts Companions would be awesome, And I would love to spitball ideas to make this a plausible Idea.
