That is fine with me. I'm glad you don't feel inclined to share everything about your character in your CS, since it adds something to look forward to in the later future. However if you have something big in mind involving his backstory, feel free to add me on skype (it's on the first page I believe) and talk me through it. You can be as vague as you want with your characters history, as long as you give me a heads up to what you have planned.
