Alright I think I have thought through what sort of power I am looking to use in this role play. It requires a bit of explaining at first; however, bare with me and see it through.

Short Version - Umbrakinesis

Long Version - My character will have the ability to manipulate a small amount of darkness. Specifically the darkness that causes him to be blind. At first it was believed that Devin (my characters name most likely) was simply born blind, but during a few dangerous moments Devin suddenly began to see and a unknown 'dark energy' sprung from his body and saved him. The way I see this being used is that at will *After much practice* Devin can focus on the dark energy covering his eyes and use them either to shoot concussive blasts of dark matter or transmit the energy into a physical object like a weapon. For short periods of time he can even 'infect' his darn energy on others making them blind. Important to note that this power does not give him the ability to teleport or control shadows. 

If this is acceptable I would like to know as soon as possible so I can continue to build around this power. If not happy to stick around and figure something else out.
