Alignment determines whether you are good or evil, and it is based on your alignment which starts at 0. Positive alignment means you are a "good" player. Negative alignment means you are an "evil" player. To receive an evil alignment, battle players who are good. To receive a good alignment, attack players who are evil. The amount you gain corresponds to the attacked players level. For example, a evil level 10 account will give +10 alignment when attack and a good level 10 will give -10 alignment.
