Yoelona
Unlike Luke, who was using the long trip to practice his skills, learn about the world, and study during breaks, Alexis, Yoelona, and Matthew were having an arduous journey.
Let's just say that the personalities of the three were not at all compatible. While Yoelona was a discreet woman who was suspicious of everything, the half-dragon was a woman who drew attention everywhere she went, both because of her appearance and her humor. Matthew acted as the appeaser of the two women's brief intrigues, that is, except when his kleptomania made him steal from someone because those were the only times Yoelona and Alexis were on the same side.
