[setr]

Its the morality (alignment) system of dnd; lawful nuetral and chaotic on the x, good nuetral and evil on the y.

The y represents what you trend towards (good v evil decisions) and the y represents the degree by which you do so.

So chaotic nuetral implies that you're generally nuetral, but its unpredictable when you'll make a good or evil decision (ie the reviewer somewhat arbitrarily lets you go on a non-critical mistake)
