You decide to meditate on the Darkness. You look inside yourself for the connection to the Darkness and you find that vast, powerful, infinite, expanse. You notice that the Darkness isn't exactly the same, that there is differences between the depths and the surface. You also realize that the Dark you can produce is actually a refined version of the greater Darkness and you can tap into the Darkness directly for greater power, at the cost of control. You can, with training, minimize the loss of control, but the Dark will always be easier to control then the Darkness. You realize that what you can create anything with the Darkness (and, to a lessor extent, the Dark), but it is limited by your control, power, and concentration. While you can simply draw more power form the Darkness, it will also make it harder to control. Right now you could create some tendrils or blades, but not very many and not anything complex, like a gear system.
[] What do you do now?
A.N. This was an info dump, but at least you know (sort of) what you can do now. Also, the Darkness corrupts the user but you don't have to worry about that right now because you are already completely curupted. You may have to work to maintain a balance if you use the Light, though.
