Elves - The elves were one of the first races created by God, and remained uncorrupted, valuing balance and nature over power. Gifted with various forms of magic, the elves appear where and when they please. Several "home planets" of the elves have been found, but it is surmised that all of these planets, while extremely old, are not the true homeworld. Elves often live in woodland areas and handcraft their technology, giving it a more natural look. They uphold high morals and have great wisdom, and play a vital part in the history of the universe in both their judgment and skill. They sometimes also act as peacekeepers. Elves are immortal due to their fine balance with nature and life.
