Heironomous H Topot
Heironomous H. Topot, or Dr. Topot for short, is the last remaining giff outside of the valley of nox. He was stranded when his airship crashed into Sky Town some time ago, and decided to make a go of it on his own, providing the residents with balloons for carrying cargo and ferrying people from stone to stone, as well as working on some airship technology that could return him home one day across the incredibly high spires of the mountains surrounding his homeland.
His relationship with the party is as a merchant and a mechanic. If there is anything to be added that neither Ethan nor Ben can conjure, Dr. Topot is the one who can do it. His asking price is always a little high, though.
