Okay, since everyone wants a way to complex techno speak answer, prepare for the Head Scientist to appease you:
First and moremost Dustarian Fire Magic does more than burn stuff, it can also be used to create forms of paramatter. This paramatter is created through the focusing of a Dustarian magi will through a crystal that has a resonation equal to that of most Dustarians. This resonation of will then manifests itself to direct huge quantities of steam through channels defined by the paramatter, then transformed into a form of propulsion energy. It's that simple, and that hard. And that's just the basics of how to power the ship!

Dumbed down version and Graal translation:
Da ships is only pilotable by Dustari's
Da crystal reads yo mind


Don't hate me because I'm a genius. Hate me because I'm conceited.
