12-year-old Aidan Errolson, comes from a long line of adventurers. His grandparents were among the first settlers of Corenwald's Eastern Frontier. His father had been one of the kingdom's greatest warriors. Aidan, on the other hand, lives the quiet, comfortable life, of a nobleman's son. He never has any real adventures, and that, he believes, is the one great injustice of his otherwise happy life. All that will change the day he first hears the bark of the bog owl, and meets Dobro Turtlebane.

But with the help of the mysterious Madame Weatherberry, Brystal is whisked away and enrolled in an academy of magic!

Aidan is living in the court of King Darrow. He has become best friends with Darrow's son Steren, and he enjoys great favor among the courtiers. But King Darrow's suspicion is growing, and his insecurity causes him to hate the young man who saved his kingdom.

They believe the ancient Wilderking Chant makes reference to Aidan, and that he is destined to overthrow the tyrant, King Darrow. Aidan has no intention of leading any rebellion.
