Icarus, the Aeternum Empire's capital!
According to the empire's historical records, this city was the first Rank 7 Artifact that Ivar the Flawless created. With Icarus, he challenged the nominal leader of a now-forgotten great organization, killing him before marching into the Void and doing the same with the Being of Law behind him.
It was that battle the one that saw the birth of the Aeternum Empire.
While Ivar soon marched into the Void and other worlds and planes, he left Icarus behind to protect his people and serve as the capital of his newly created organization.
Icarus, while technically a city, was almost as large as a Principal World's continent. Its power was so immense that other than the Eye Dynasty and Scientia Kingdom, there was nothing in the Magi World capable of withstanding its might.
