Sacred represents who I am. Sadistic, kind of cold, sarcastic, loner, irreverent, etc.
Ruby represents who I was. Shy, withdrawn, head-in-the-clouds, imaginative, academic, etc.
Rayne represents who I want to be. Brave, courageous, forthright, moral, always knowing what to do/say, etc.
They're all of course loosely based on me, and at times I'll display personality traits of any of them. While I am kind of in a non-personal mood at this time in my life, it doesn't mean I cannot revert back to who I was at times, or look ahead and try to start being who I want to be.
