Enon - The Age of Lamentation
A neutral character does what seems to be a good idea. She doesn't feel strongly one way or the other when it comes to good vs. evil or law vs. chaos (and thus neutral is sometimes called “true neutral”). Most neutral characters exhibit a lack of conviction or bias rather than a commitment to neutrality. Such a character probably thinks of good as better than evil—after all, she would rather have good neighbors and rulers than evil ones. Still, she's not personally committed to upholding good in any abstract or universal way.
Some neutral characters, on the other hand, commit themselves philosophically to neutrality. They see good, evil, law, and chaos as prejudices and dangerous extremes. They advocate the middle way of neutrality as the best, most balanced road in the long run.
Neutral means you act naturally in any situation, without prejudice or compulsion.
