Excluding Nigellus which was the capital of the empire, Solis Nigellus was comprised of twenty-two duchies.
One duchy, Valyenor was a former allied kingdom that joined with Nigellus. Twelve of the duchies were kingdoms defeated in battle by the former Nigellus Kingdom during the reign of King Solis Nigellus. And the rest were smaller territories that were either conquered or surrendered when the empire was formed.
Eons ago these territories still had grudges toward Nigellus. They wanted to part from it and regain their freedom. But after all the years that had passed and the millennia of prosperity they had under Nigellus, all those were forgotten.
The twenty-three territories that formed the Solis Nigellus empire were now living harmoniously. There were competitions here and there and uprisings every now and then, but they remained as one empire.
