Omega

The world was divided by character
Alpha: A leader, a dominant and confident person who strives to be the center of attention and in control of the situation.
Beta: A calmer, more driven individual who often takes a supportive position and does not strive for primacy.
Omega: An outsider or person at the bottom of a conventional hierarchy, often withdrawn or uninterested in social success.
Sigma: A loner who possesses the leadership qualities of an alpha, but completely ignores the rules of hierarchy and does not compete with others.
Enigma: A mysterious and unpredictable personality whose behavior is difficult to classify into standard patterns.
