Lawful Good is known as the "Saintly" or "Crusader" alignment. A Lawful Good character typically acts with compassion, and always with honor and a sense of duty, and unlike Lawful Neutrals, these characters put doing good things above obeying to the law. A Lawful Good nation would consist of a well-organized government that works for the benefit of its citizens. Lawful Good characters include righteous knights, paladins, and most dwarves. Lawful Good creatures include the noble golden dragons.

Lawful Good characters, especially paladins, may sometimes find themselves faced with the dilemma of whether to obey law or good when the two conflict—for example, upholding a sworn oath when it would lead innocents to come to harm—or conflicts between two orders, such as between their religious law and the law of the local ruler.

They are the moral opposite of Lawful Evil, the Law/Chaos opposite of Chaotic Good, and the complete opposite of Chaotic Evil. Stereotipically, Lawful Good characters are seen as the most honorable characters, but Neutral Good and Chaotic Good characters may definitely be honorable as well in their promotion of goodness.

Lawful Good characters can count as Pure of Hearts if they have no corrupting factors as both archetypes can be identified through traits such as acts of kindness like saving lives or being pleasant with other characters.
