"Well, unicorn magic is hard to understand if you're not a unicorn," he says. "And elven magic is hard to understand if you're not an elven mage or bonded to one. It can do the most obviously impressive things, though, out of all the other common kinds. An elven mage can raise a stone bridge out of nothing that will stand for thousands of years. It's also sort of impressive that they can make new species of plants, but Aianon can do that too and he seems to be even better at it. Or maybe he just does it more often."
