Please almighty and benevolent ichtys! Let us have airships! They dont need propellers and ships have been around way before medieval times! There could be a coven based around Air Raiders like the Greyjoys!

Edit: Greyjoys of the air. Their power lies in their air fleets and they raid the lands around them. Their castle is high up some mountain, so they have no land for crops. They let other covens use their airships and their crews of Aeronauts in exchange for supplies!
