The demon lord Vyriavaxus is the latest of the notable victims of Nocticula. She seduced and killed him, and, as is her custom, there is now one of the Midnight Isles in her Abyssal realm whose themes are based around him.
His cavernous realm of Rankarrus was close to that of Camazotz's Argahoz, and some speculate that Camazotz may have been his sire. He was the patron of the shadow demons, and Nocticula killed him to gain control over them. Nevertheless, some shadow demons maintain loyalty to Vyriavaxus plotting to resurrect their former master.
