The elves in the Winterbough Saga and the Ballad of Adler Young are anthropomorphic animals. They are essentially humanoid with features and traits analogous to various feral animals. Different animal species represent different "races" of elves. Normally, races cannot interbreed. Inter-species venery is not discouraged by the Mephitist Church but all elves acknowledge that in order to reproduce, a partner of the same race is required.
Most elves possess magickal powers to a greater or lesser degree, and they have very long life spans.
Elves do not lie.
