Join Gwain in ignoring all common sense, at least according to his parents, and believe the Magistrate’s ancient advertisement. Step into the Wilds of Alluria with his fellow adventurers, discovering quickly that navigating this unmappable land and its unpredictable creatures requires more than optimism, especially since "free" has a very Allurian definition. Armed with compasses that may or may not have a mind of their own, they must follow their lead to unravel the truth behind the mythical Magistrate's city and the ancient advertisement. They must choose whether to trust their questionable instincts and prepare for their understanding of reality to be thoroughly unhorsed by the truth, including that of unicorns.
