Could it take several more centuries for Draxus to return to the capital and become the supreme leader of all Chaos Dwarfs, to become the most favored and beloved child of Dark Father Hassut?
No, the Black Magic and war machines possessed by the Chaos Dwarfs far exceed the power of Charlemagne's Empire. Draxus will prove his excellence and correctness through a real war. Humans? A bunch of insignificant trash. Indeed, perhaps Tamu Khan's suggestion has merit. Draxus should indeed form an expeditionary army to conquer Charlemagne's Empire and incorporate all the mysteries of human engineering and magic into his grasp. When he returns with victory and glory, he will become a rising star in the eyes of Dark Father Hassut, shouldering the heavy responsibility of the Chaos Dwarf Dark Empire. This should be his mission.
