Adarin Kordyne was a male Long Patrol hare who served under Lord Brang Forgefire. He was the son of Feryn Kordyne, father of Buckler and Clerun Kordyne, father-in-law of Clarinna, and the grandfather of Urfa and Calla. He was wiser and more peaceful than some Salamandastron hares; because of this, Lord Brang trusted him as a faithful advisor and counselor.
Adarin's father, Feryn, was the original Blademaster of Salamandastron; when Feryn passed on, Adarin inherited a Broadsword and the Blademaster's Medal from him, as he was the eldest son. As Buckler noted, Adarin was not a warrior or fighter, and therefore had no need of the tokens; however, he kept them and passed them down to his eldest Clerun, continuing the tradition.
Adarin was a minor character; nothing else is known.
