Perhaps their level of technology fluctuates as time goes on, and they often lose the science of their inventions, so they know HOW to make things work, but they don't know WHY. This would explain how the most advanced dragonator is also the oldest, and capable of working underwater. And why they have both ballistae and cannons. So basically they are kept in a perpetual state of technological advancement, whether on purpose or by natural disasters (an example of this is how the Moga civilisation was essentially destroyed by a Ceadeus centuries before MHtri).
