From what is known about Sarah she is very big on history and prophecies. She comes into the muffin and usually takes a back corner seat with a glass of water. She has only actually talked to a few people, Trina being one and Asphiel another.

She always carries with her a small magical journal where she keeps all her prophecies and notes. She is a magic user by nature and tries to hide the fact, not knowing how any might respond. She herself holds another secret that will only be revealed when the right time comes or her magic runs out. ((which since it's an inborn force, won't happen unless she dies))
