The Duchy of Tirian was a Charisian patent of nobility, making its holder the secular ruler over Tirian Island as well as Constable of Hairatha.
In the Year of God 890, the duchy was held by Lord Kahlvyn Ahrmahk, a first cousin of King Haarahld VII and son-in-law of Rayjhis Yowance, Earl of Gray Harbor. However, after the Duke was revealed to be a traitor by Merlin Athrawes, he died in a struggle by the hand of his father-in-law.
His firstborn son, Rayjhis, succeeded him both as Duke of Tirian and Constable of Hairatha. (OAR)
