Venethan Rosewood wasn't always evil. Ambitious, certainly, but not evil.
He had been born the simple son of merchants but had no intention of taking over the family business. He had higher ambitions. He wanted to be known as one of the greatest users of magic in the fairy realm.
He wasn't content to settle for mediocrity like his parents. Magic was important to fairies but many of them never bothered with more than the basics.
Not him. From the moment he was old enough to learn how to control his magic properly, he spent every free moment studying. That caught the attention of one of his neighbors, who happened to be rather proficient in magic. Dew Cloudblossom, a wind fairy, recognized his natural talent and took him under her wing.
She also recognized his desire for more than the life of a merchant. So when she became the princess's magic tutor, she approached him with an unexpected offer he couldn't refuse.
