The Eastern Del Vecchio Dynasty was a line of Thannish rulers descended from King Castenar; who founded the kingdom of Thûle in 1209/4.
The eastern Durethë line began in the early years of the Fourth Age, when King Aron Del Vecchio of Eldara conquered the eastern Kratheri Peninsula and sent his son Prince Daghon to rule from the East as a separate realm. Over the centuries, the eastern Eldarans grew more and more resentful toward the Royal Court in Eldarand, and finally, led by Prince Castenar, they revolted in 1202/4 against the monarchy of his own father, King Arathar IV. After Castenar’s victory in the First Eldaran Civil War in 1209/4, the Durethë line in the east continued to rule the newly established kingdom of Thûle.
After the kingdom of Thûle won its independence, the Del Vecchio family ruled Thûle for 131 years and a total of five of its monarchs sat upon the Obsidian Throne at Castle Terathar. The Dynasty ended in 43/5, with the death of King Caronius, who was slain in the Battle of Ralansyr ending the Unification Wars.
After Caronius' death, House Del Vecchio was overthrown by Mordred Mankhari. After he declared him self king, Mordred had all of the remaining Del Vecchio family members either killed or forced into exile.
