1. Naturally, Davin loathes those who would shun him or think less of him for his race, though he generally treats them with superficial courtesy. Davin has encountered few of the more open-minded humans, and when he has, he doesn't know what to make of them. He prefers to keep his distance even to the humans who show him the most kindness.

Davin would much rather see his people free to act as they wish, without having to strain to be unlike humans. Elves, in his mind, already possess a natural grace and intellect that is superior to humans, and have nothing to prove.
