I tried my best not to use any non 'exotic' technology, to keep it as close as possible to the canon. The Witch behind some of these inventions is the Leonardo Davinci of MGE and she's obsessed with flying. She got the Idea of sleek airships to improve aerodinamics watching kids play with a hand launched airplane model.

Yes these are produced in Emmeria, but some can be exported to allies.
