Dragon Booster S1 Ep07 - The Horn of Libris

Moordryd wins the Horn of Libris race by cheating, using a wraith dragon to slow Artha and Khatah, the Horn of Libris champion down. Moordryd succeeds and both Artha and Khatah find that the horn calls the ancient grey draconium dragon, Libris, for battle and they both intend to get the horn.
