The Irryllian homeland lies to the south/southwest of the city-states. It is mostly subtropical/Mediterranean in climate.
It is quickest reached by ships sailing west then south from Ironport for about 800 miles or a week’s sailing to the cityport of Whalesong at the edge of the Irryllian homeland.
Total population is about 50 million, 30 million of whom live in the homeland, the rest in distant provinces and colonies such as the City-States of the Sorquos region.
Current ruler is Emperor Voraxis III, of the royal house Julianus.
The capital is Eldiss, with a population of 500,000, about 1700 miles due south of Delliron.
There are numerous other colonies and provinces, many of which are more populous than the City-States.
The Empire has lasted for 2500 years, but has fluctuated in both size and culture.
The Empire is not entirely stable. There are a number of dukes and archdukes with tenuous claims to the Imperial throne and large power bases.
The army is basically feudal, most of them loyal to the noblemen who in turn owe allegiance to the Emperor. Only a quarter of the troops and officers are directly loyal to the Emperor.
