Horn of Libris
The Horn of Libris is an ancient artifact used to summon the powerful dragon Libris. It was originally given to the Ancient Dragon Booster to be able to call the Grey-bone dragons at the right time during the Dragon-Human War. Today it is portrayed as the trophy prize for the annual Horn of Libris race, which had always been won by The Inner Order Crew every year up to date, until Moordryd raced and won it at last. Artha Penn and Khatah rescued the item, where it was then stored away at Dragon City Security in Precinct, until Rivett gets his hands on it during the events of Episode 23: The Mechanist.
