Alignment
A character's alignment is an easy way of summing up their moral ideas, and represent their general moral compass. It has 2 axes, and each axis has 5 magnitudes.
Most people tend towards Neutral. On any one axis, 75% of people are Neutral, 20% of people are one step away, and 5% of people are at an extreme. However, adventurers and those that adventurers combat tend to the extremes more so than most.
