That is an excellent idea. Together with the other stuff I read here, I think I know what to go for. I love the idea of the character trying to garner favour with the idol only to end up being ripped off when he is on the path to his grand goal. Thanks a lot for the idea!
Something about that airship idea tickles my memories of playing Final Fantasy, so I can't say no to that. It's also something that would certainly garner massive favour, while not making the characters feel overly powerful beyond reason. Especially once the airship has plenty of limitations for being a prototype it's fully under DM control and still feels incredibly cool, I imagine.
Thanks for the idea, I think it's really shaping up.
