What Alignment Means
Alignment is central to a D&D character’s personality. D&D uses two measures to determine a specific character’s ethical and moral attitudes and behavior.
The moral axis has three positions: good, neutral and evil. Good characters generally care about the welfare of others. Neutral people generally care about their own welfare. Evil people generally seek to harm the others’ welfare.
The ethical axis has three positions as well: lawful, neutral, and chaotic. Lawful people generally follow the social rules as they understand them. Neutral people follow those rules find convenient or obviously necessary. And chaotic people seek to upset the social order and either institute change, or simply create anarchy.
