Yngvi is one of the six dukedoms of the Kingdom of Grannvale in the Jugdral Series. It was founded by Ullr, the Bowmaster, and ruled by Duke Ring during the first generation and Scipio during the second generation. The Holy Bow Yewfelle is passed down through the Yngvi family. Their knight squadron is known as Beige Ritter and is made up of Bow Knights.
In the first generation, Duke Ring and Andrey departed with the Grannvale army to go to war with Isaach. With the areas surrounding Grannvale mostly defenseless, Verdane launched a surprise attack on the Castle, with Verdane's prince Munnir capturing Edain with the intent of forcing her into marriage. In response, Sigurd launched a crusade against Verdane in order to rescue Edain.
During the war against Isaach, Ring is falsely accused of assassinating Prince Kurth much like how Byron and Sigurd were. In truth, Andrey had allied with Lombard and Reptor and killed Ring, taking over rule of the duchy. Lending his army's assistance to Myos and Daccar in the Silessian civil war, Andrey dies fighting Sigurd in the leadup to the Battle of Belhalla, with his rule passing to his son Scipio, who works with Friege in fighting Seliph's army, only to be defeated. At the war's end, Febail, Brigid's son and inheritor of Ullr's bloodline, may take over Yngvi from Scipio if he doesn't inherit a different throne from his father.
Possibly the most remote of the duchies, it is situated some distance southwest of Chalphy, and the Jun River that flows from the northern lake is a natural border between it and Verdane's border castle, Evans.
