User blog:Error404:NameNotfound/I am new here, so....

A few questions, and a request for help. Can benders have non-bender skills? If not, why not? Help request lies below, tell me if over the line: I want to make a character, I know what he looks like, his personality, etc, but I am having trouble with his history. I need help writing a history for: A mentally unbalanced Firebender, age twenty-one, that was traumatically injured, causing his right eye to change color, who is a loner, possibly an orphan, possibly scarred mentally by a horrifying occurrence. (I'm not good at this, I'm better at dialogue. I know kinda what I was his history to look like, but I can not put it together.) I don't expect the whole 3 paragraphs, just a little help. Sorry if I sound like a noob or a lazy person, and thanks in advance.
