Darkness is not Harm. Darkness is not black colour.
The darkness is a state of mind. It is when you want to live in night.
It is when you want to sing, to dance in night.
The darkness is beautifull and to its opponents it is dangerous.
But to the lovers of Darkness, the Darkness is safe, lovely and beautifull, it will caress and will embrace.
Many humans are afraid of Darkness and of night, but this phenomenon proves only their nonsense.
The darkness covers you, hides you in night.

When there wasn't anything, there was only darkness. Without light, darkness has abilitie to create anything from herself, and she created Baron of Darkness. Darkness has another abilitie - The Void, or negative darkness. With this abilitie darkness can return everything in darkness (Black hole for example). Baron of darkness has two of these abilities and no light in existance could prevent of using them.
