You weren't being too touchy. I was being too literal. It wasn't my intention to imply anything. It was an honest question, but I can certainly see how it came across. I do owe you an apology. Sometimes I forget that text does not adequately convey emotion or a question mark. I am very literal, so if I ask you something, I'm really asking. When I'm being snide, it is hard to miss. In this case, I was snide by accident and for that I am sorry. I do think we profoundly disagree on the core of the story though. We will have to agree to disagree. I am a firm believer that both God and the devil are in the details. What you described as the core of the story above is most certainly not a story. It is an idea. As an aspiring writer, I can tell you that is exactly how you start. You say to yourself one day, "I should write a story about this knight on a quest to defend a tower. It will be a long journey and involve all the people he meets."
Do you see my point? That isn't a story. That is the barest bones of an idea. Stories are about people, i.e. SPECIFIC people and the details that make their lives and quests stand out from all the rest. Without a doubt, history (and fictional history) is full of knights. It is the details that makes Roland THE Knight. I know I sound like I'm making a mountain out of a molehill, but I'm really not. There is a reason Stephen King's stories resonate with us. You can walk into any bookstore and find WALLS of stories about knights (modern, archaic, futuristic) and we don't know their names, nor do we really care. That is because they are, by in large, vaguely drawn cartoons following the quest of the day. It isn't the quest. It isn't the monster. It is the people we care about, and people are defined by specific context. Change the context, change the story.
