The Horned Crown was a huge crown that was created by the Celestial Stag to hide his Shadow Magic powers in at the end of his life. However, the object was cursed: whoever wore it would be transformed into a dragon known as the Pendragon. When the Celestial Stag died, the Horned Crown was buried with him in an unmarked grave in a small inconspicuous cemetery in The Wyrd. For the next 35,000-or-so years, the Horned Crown lay in the Celestial Stag's coffin as his body rotted away. Sir Michael Jones, one of Tate's henchmen, heard about the Horned Crown in an old legend and went out to discover if it was truly real. After doing all the research he could, he eventually found the Celestial Stag's remains and dug them up, taking the Horned Crown for himself. A few years later, when Sir Michael Jones and Tate decided to overthrow Weasel and King Arturius, Tate simply placed the crown on their heads, transforming them into the Pendragon for the next 10 years. After the 10 years, Nate defeated the Pendragon, separating it back into Weasel, the Horned Crown, and King Arturius. The Horned Crown was then absorbed into Weasel's Sword of Caliber, giving him the power to learn Shadow Magic without tainting his soul.
