Adult Red Dragon
Jahlvoraz was sent the cathedral to serve as a messenger between Urathash and the Storm Tyrant. The dragon is mostly bored with his duties, though his magical compulsion prevents him from abandoning, or even questioning, his assigned task.
Jahlvoraz often perches on the carved stone anvil at the spire’s apex to survey the ground below, but he returns to this chamber immediately if he notices anyone entering
his lair. The dragon seems to be under some sort of mental domination.
