Neutral Good is one of the nine alignments in Dungeons and Dragons
System Reference Document
Neutral Good, "Benefactor"
A neutral good character does the best that a good person can do. He is devoted to helping others. He works with kings and magistrates but does not feel beholden to them.
Neutral good can be the best alignment you can be because it means doing what is good without bias for or against order.
Neutral good can be a dangerous alignment because it advances mediocrity by limiting the actions of the truly capable.
Neutral Good: Unlike those directly opposite them (Neutral Evil) in alignment, creatures of neutral good believe that there must be some regulation in combination with freedoms if the best is to be brought to the world - the most beneficial conditions for living things in general and intelligent creatures in particular.
Neutral Good is known as the "Benefactor" alignment. A Neutral Good character is guided by his conscience and typically acts altruistically, without regard for or against Lawful precepts such as rules or tradition. A Neutral Good character has no problems with co-operating with lawful officials, but does not feel beholden to them. In the event that doing the right thing requires the bending or breaking of rules, they do not suffer the same inner conflict that a Lawful Good character would.
In the Complete Scoundrel sourcebook Zorro and Spider-Man are cited as examples of neutral good characters.
The Neutral Good outsiders are known as Guardinals.
Sweetness and light. Doing good is more important than upholding the law, but law is not a bad thing. Not too caught up in Order Versus Chaos; concerned with moral goodness, but often not willing to enforce it in others. If The Messiah isn't Lawful Good, they're probably Neutral Good. Just think "basically nice person" and you've probably got it. (For advanced learners, there's Good Is Not Nice.) Neutral Good states may be really nice places to live, but depending on how idealistic the setting is, they may be deluding themselves. The guardinal celestials of D&D, beastlike creatures who inhabit Elysium, are Neutral Good.
Neutral Good is considered an Honorable Alignment. This means that Neutral Good characters are harmed by Dishonorable spells and effects. Honor is generally relevant in Eastern campaigns.
Neutral Good is combined with Chaotic Good in an alignment simply called "Good" in 4th edition D&D
