I've been having the hardest time nailing down my characters age. Some days I want her to be in her early twenties, other days in her late teens, other days a little younger than that. I literally cannot decide or determine how old she's supposed to be. And because of that, all of the people around her are ageless as well, since I want them all to be around the same age. Is it important to nail down age in a fantasy? She won't be going to high school or college or anything like that. The only thing I can think not having an age could hurt would be the timeline. If I mention she did something "fifteen years ago" then later put "twelve years ago," it could get confusing. So as long as I limit exacts to the timeline, is it possible to leave age out of it? Opinions?
