ALIGNMENT

Alignment is an indicator of whether someone is good or evil. A positive alignment indicates goodness while a negative alignment indicates evil.

Alignment helps determine what classes, spells, abilities, and so on, a person can have. For example, an evil character will not be able to become a Paladin.

Alignment can also determine how the denizens of the mud react to a character as well.

Somewhat related to alignment is faction, which determines how denizens react to others based on the factions they are a member of.
