alignment. A character of this alignment is an individualist who follows his or her own heart, and generally shirks rules and traditions. Good and Evil come a distant second to their need for personal freedom, and the only reliable thing about them is how totally unreliable they are. They typically act out of self-interest, but do not specifically enjoy seeing others suffer. Many free-spirited adventurers are of this alignment. Alternatively there are madmen whose actions are chaotic, but are not themselves inclined towards evil.
- An unusual subset of Chaotic Neutral is "strongly Chaotic Neutral", describing a character who behaves chaotically to the point of appearing insane. Characters of this type may regularly change their appearance and attitudes for the sake of change, and intentionally disrupt organizations for the sole reason of disrupting a lawful construct. Characters of this type include the Xaositects from the Planescape setting, and Hennet from the third edition Player's Handbook. In Advanced Dungeons & Dragons, Chaotic Neutral was frequently assumed to refer to this subset. -- from
