A single person may have many different personalities. I'm not talking about someone suffering from Multiple Personality Disorder or anything like that. In different circumstances and with different people, won't the same person act, think and feel differently? I'm sure you feel different when you're in work or school than when you're with your parents and family, and different again when you're out with friends.
I have a great interest in the way human personalities work, and while there are professionals out there who doubtlessly know far more than I do about the way the mind works, I do like to think that I know my own self pretty well. Even as a child, I noticed that I would feel and behave differently in different circumstances, and that these differences each had a specific "feel" to them. After a time, I could distinguish several aspects of myself, going so far as to visualise and name them.
The four names below each represent a part of myself. Perhaps by knowing each individual aspect, it can be possible to know the whole person. Or perhaps I'm just a very wierd person. Make your own decision.
Ark - Tinted with blue, Ark embodies my feelings and emotions, particularly those of joy and sorrow.
Chion - An angry purple, Chion represents my feelings of anger and rage, and my base instincts.
Sharve - Bathed in white, Sharve is my calm, my discipline, and my warrior spirit.
Extrial - Shadowed in black, Extrial manifests as my individuality, and my affinity for darkness and night.
