- You may be looking for the 3.5e SRD description of alignment.
Alignment is used to determine the basic motivations of a creature. Any creature with a stat block also has an alignment.
Alignment is determined on two axises: Law-Chaos and Good-Evil. The Law-Chaos axis has Lawful, Neutral, and Chaotic. The Good-Evil axis has Good, Neutral, and Evil.
Alignemtn in DnD 4e is simplified greatly from 3.5e. There is only one axis, consisting of five values: Chaotic Evil, Evil, Unaligned, Good, and Lawful Good. Mechanically, the only rules that use alignment are for clerics, matching the same alignment restriction rules that clerics have in 3.5e.
