Ether that, or one was their ticket out of Al-Hazard. * And maybe, in keeping with the general theme of this thread, Al-Hazard is an Ancient outpost, and magitek as seen in the Nanohaverse was invented by the Ancients along their path to Ascension. And the Ancients are the reason why the people of Midchilda and (probably) practically everywhere else are human. They had time travel, and the ability to become energy, so... Interdimensional travel isn't all that far out of the question for them.
