From the introduction: Ogres breed trouble. When said Ogres turn to hedge wizardry, without the slightest idea of the consequences, you've got a recipe for disaster. So, meet Bartuk Caballa, an Ogre quite unlike the vast majority of his kin. Instinctively talented in the arts of sorcery, hopelessly naïve and ignorant of the workings of human society, though blessedly friendly of nature. His only wish is to be accepted into the Colleges of Magic in Altdorf, and pursues this quest with a determination only the complete ignorance of its folly could warrant.
