Theme Brainstorming— A Fantasy in Making

Currently, I am writing a free write story for my own entertainment. I’ve been writing since the Tuesday before school started and have about five chapters completed and other major scenes in the making. The story is about a young girl who fits the profile of a prophecy and has to find a missing gem to prevent chaos and havoc spreading across the entire world.
There are many interesting scenes that give the main character, Lunesca, the personality of a tomboy in a mideval fantasy setting trying to find someplace where she can fit in. I also placed some scenes that also give Lunesca sort of a separate part of her personality that is buried deep within herself. So there are many things I still need to think about to give the story a consistant theme or story pattern that a reader may be able to follow and understand.
One of the things I thought about including in the story was a prince falling in love with Lunesca. This idea was actually a theme borrowed from a book I read over the summer. I thought that this would eventually help recover that separate part of her personality. Another scene included in the story is how Lunesca almost gets raped while fleeing from danger. I thought that this would reinforce the theme of a persona of more feminine quality buried within her because of difficult events of her past when she presented her feminine qualities more openly. I thought that if she were more exposed to the masculine side of a person, the feminine side of her would be cast aside because Lunesca thinks that women are weaker in personality, but strong at the same time. By having this opinion, I am trying to incorporate the notion that Lunesca would try to prove to herself and others in her life that women can also be strong even if they are generally thought inferior to men in society.
Another important theme I thought about incorporating was how Lunesca deals with relationships between different people. Early in the book, Lunesca talks about how her father was distant from her and her second oldest brother. This would maybe show Lunesca that not all relationships may be worth trying to strenthen because when she tried to strengthen her relationship with her father, the father-daughter relationship did not improve. Another failed relationship was between a young man named Eyvind. Lunesca and Eyvind are supposed to be great friends. Eyvind was supposed to be part of the expidition accompanying Lunesca’s group, but Eyvind dies early in the expidition. So this relationship may show Lunesca that her personal relationships may not be worth to strengthen because of the dangers in the life she leads.
