Tyndyrth the Gold

Tyndyrth was a powerful gold dragon who was born the Ancient World, lived through the entirety of the Middle Era, and survived briefly into the Dark Age. They eventually grew so wise that they were known as the "Dragon Oracle", or Draracle, to the denizens of the Elsir Vale. Tyndyrth single-handedly defended Elder City during the Ultima War, using their powers as an Exarch of Bahamut to repel Vecna's forces.
