One of the seven great wyrms born of Midgardsormr, Vrtra took Thavnair as his home, where he lived in solitude for many centuries. This quietude was broken, however, when he brokered peace between warring tribes, and involved himself with the founding of Radz-at-Han. Since the city-state's establishment, he has ruled in secret alongside generations of satraps, guiding the people from behind his conspirators' mortal facade.
