I write because I have entire worlds, bustling with life locked up in my mind. The so-called "real" world deserves to know the story of these people, and I must bring them to life... Nay, they are already alive to me. I must bring their lives to you, you must know all about their heroism and cowardice, their rise and their fall. People deserve to hear these tales as much as these tales deserve to be heard.
If you could have one professional artist, living or dead, collaborate with you on your writings, who would it be? I use the term artist in the most broad meaning here. It can be a painter who illustrates your poems, a director who films your short stories or novels, or a musician who records your lyrics, or whatever you see fit.
