Yderat is the capital city of the Imperial District of Kalsaivi. The city was likely settled by the Kalsaiv People around 500 DC, though Yderat-Nakan, like the rest of the Nakan, was built significantly earlier.
The city is split into four primary districts: The Temple Grounds, consisting of Yderat-Nakan, the Old City, the narrow, winding streets surrounding the Nakan, the New City, the more open section built around 100 years before the Imperial Invasion, and the Imperial Annex, a small district housing Imperial officials.
