Descendants of the Darolm, the Isulvjar, known as the Dragon-Men by most, are native to the northern land of Isul, the highest nation in Mammarkay. They are talented magic users, as well as the progenitors of Kjallerik, or Summoner’s Marks. The Isulvjar were created from the Darolm in fulfillment of their side of Otar-Din's Pact, pledging their allegiance to the god in exchange for his teachings of peace and the retention of their sentience.
