Radiant Vol. 7 (manga)

Lords from all over Cyfandir are gathering to choose young Wizard Knights deserving of being their heirs. Seth, meanwhile, continues training with his mysterious tutor in the even more mysterious Caillte Forest, where strange creatures roam and time flows at a very different rate from the rest of the world. While there he also learns of the "Little People" and that he could very well play an important role in helping them to return from near extinction.
