To the forest on the shore of the Kingdom of the Isles, the orphan Pug came to study with the master magician Kulgan. His courage won him a place at court and the heart of a lovely Princess, but he was ill at ease with normal wizardry. Yet his strange magic may save two worlds from dark beings who opened spacetime to renew the age-old battle between Order and Chaos.
