Created by Defluo in a parallel experiment to the creation of Tiamat shortly before the godling vanished from the world mysteriously. The divine egg was created by placing the heart of Agrilnost inside one of the discarded eggs from Ator's early dragon experiments.
The Divine Egg is a heavy, black, egg shaped objected mottled red, and seemingly made out of some unknown metal. It was claimed by Tiamat when she rose to find she had no master. It's effect, and where the dragon exarch keeps it are unknown.
