Syr is a fictional princedom in Melanie Rawn's fantasy novels of the Dragon Prince and Dragon Star Trilogies. Syr is a southern princedom famous for its wines and rich soil. Syr has been a battlefield in many wars, including the War of 704 between Princemarch and The Desert. Roelstra used Prince Jastri of Syr to fight against Rohan. The young Prince was killed in battle, leaving only his ten winter old sister as his heir. During the war, Lady Andrade of Goddess Keep and Rohan of the Desert declared Davvi of River Run the new Prince of Syr. After Roelstra's army was defeated, Davvi led his River Run soldiers against High Kirat so that he could establish himself as Prince in the royal seat of Syr. In 705 Davvi and his line were confirmed as Princes of Syr.
