Adian was the mightiest and most crafty of the heroes of antiquity. An ancient Thalesian Hero, Aidan imperilled his soul twice, while consorting with the Troll Gods, once when asking for the location of Ghwerig and again to gain entrance to his cave. He stole Bhelliom from Ghwerig's Cave while Ghwerig was trying to retrieve the rings from Aphrael. When he returned to Emsat, he was promptly crowned King of Thalesia and mounted Bhelliom on the Royal Crown. The crown was lost once when King Sarak died and again when Ghwerig fell into the chasm in his cave when Sparhawk regained the Bhelliom.
