The Dark Queen

There is a queen with a heart made of darkness. A pure soul gone wrong. The earth turns black from just a touch of her fingertips, and a good soul becomes evil at her presence. She is the dark queen.

However, there is also a man with heart almost as pure as hers once was. A man that enters her kingdom and doesn't become evil. He makes a deal with the queen that he can show her how to be good, and she argues that she can turn his soul to darkness.

Let me ask you one question though. What happens when darkness is introduced to the light ?
