A cheerful boy from the outskirts of Riman

He has the Rune of Mastery. It's between his shoulder blades and is shaped like a three pointed crown, but he has no idea what it is. He thinks it's just a weird birthmark.
Lucas, or Luke as he prefers to be called, is generally a happy guy. It is rare for him to get angry or upset, and he usually has a smile on his face. He's always been a hard worker, mostly because it takes a lot of work to help run his family farm. These traits combine to form a guy who is generally like by the people who have met him. The only time he ever loses his smile is when the topic of his brother comes up, but most people around him are tactful enough to leave that subject alone.
He has nice, sturdy leather clothes that are good for just about anything. They're water resistant, weather resistant, and durable to boot. Perfect for working in the dirt of a farm. The only thing valuable that he has is a medallion that he wears around his neck made from gold and diamonds, a memento from his mother who died of illness when he was only 9 years old.
Luke's life is really nothing to write home about. He lived with his father, mother, and brother for the entirety of his young life, up until the age of 9 when his mother died form an unknown illness. His brother left home when Luke was 11, saying that he had to go and find out exactly what mom's illness had been. If anyone could do that, it was certainly Luke's brother. He was a certifiable genius, better at everything than almost anyone else. He could do complicated math problems in his head, write elegant pieces about the world around him, figure out exactly why things did or didn't work, and could always lift twice as much as other kids his age. Luke always had an inferiority complex about his brother, which only got worse once his brother left. People would just never stop comparing him to his oh-so-perfect brother, and he resents that highly. Of course, the only person who he has told this directly is a childhood friend from his hometown, Riman.
