[@ClocktowerEchos] [s]Never deal with a dragon.[/s] Perhaps. So, there could be dragons that have their own motives and plans, and probably have influenced the world over the course of centuries. But how long a dragon would live naturally? A few decades, a century?

And mashing science and engineering with magic... in a JRPG named Lost Odyssey, magic energy fueled an industrial revolution, like fossil fuels did in the real world. Perhaps a race engineered a powerful automaton/machine that took its fuel from magic.
