Duke of Zijinlin

Duke of Zijinlin (known as Duchess of Zijinlin if held by a woman) is a title of nobility in the Imperial Peerage of Shireroth, created by Kaiser Ayreon V in 1741 for his great-grandfather Hon ben Gyoku for his services as Regent of Shireroth. In 1749, the title was inherited by Kaika bat Gyoku (Hon's granddaughter). When she died in 1750, her grandson Kaiser Ayreon VI inherited the title, which then merged with the crown.
