HEROES OF IMPILTUR
Xonox was an ancient Abyssal Wurm that lived over 1,000 years ago. It was slain by the Minotaur hero Targore and his companions. The demon was reportedly very powerful but it is unknown where it fit into the hierarchy of the Abyss at that time. Whether it commanded a layer of the Abyss itself or was a servant to a more powerful demon is lost in the annals of history. Obviously the demon played a pivotal role in the war between the Hucan and Narfell Empires because history reported that the war concluded after Xonox had been slain.
Targore’s Horn of Demonfire was taken from the head of Xonox after the demon was killed.
Xonox was also one of the demons that had their name inscribed on the Demonstone and had a level of the Demontower devoted to him. Because Xonox had been destroyed, by the time the party entered the Demontower, his level no longer held any of his power and therefore was used as neutral territory by the Fraternity of Tharos. This also explained why Tsol’s Horn of Demonfire allowed him to enter the tower since it had been taken from the head of Xonox after he had been slain.
