Nano-technology - Not Sufficiently Advanced, as per the Arthur C. Clarke gold standard of sufficiently advanced technology.
Dwarven Mountain Pony - a small, and hardy animal well suited to living in the mountains and highlands. Able to subsist on grass and brush, with hard hooves, and nimble feet. The dwarves use them as pack animals, and to pull ore carts, and to drive bellows for their furnaces. Never ridden as dwarves like to keep both feet firmly on the ground. As stubborn and tough as the dwarves themselves. Also only about 12 hands tall (1 hand=4 inches)
