Mya(Black one) and Kya(White one) were once sisters. Their parents had forbidden love. The father was dark. The mother was light. There happened to be a baby of each. They grew up, being able to go in the darkness and light. When they were teenagers, their mother died and Mya grew darker. She wanted her sister to feel miserable. She was flying in the coulds when:

Mya: Come with me to darkness. You will feel much better. You get revenge. Nobody is honest. Everything's great.
Kya: It doesn't sound great. I like it here where everypony is nice and honest. They help you when-
Mya: That sounds TERRIBLE!!
Kya: Its true harmony.
Mya: Yeah right. You're coming with me.
Kya: No! I love it here. You can't make me.
Mya: Oh really? -Uses horn and black magic to force her there paining her with darkness on the way-
Kya: No! Stop! Mya! You're my sister! Not a beast!
Mya: Shut UP! I'm NOT a beast!! -Makes her cry by paining her so much-
Kya: -Cries- No..... I beg you.....
Mya: Oh you beg me? Big deal. You'll feel better here....
