Irisis

On the center of Alastaria there is The Great Forest.

Left from it, there is an arid region called Irisian Desert.

It's a desert because IRINOS the Aeon creator of light, fire, sun and stars, placed a small star floating onto that place.

The star made the place hotter and on it's center is ever-day (night seems like dusk)

This is how the Irisian Desert was created.

Right under the Irisian Sun, human ancestors build up a golden obelisk pointing at it, and a triangular wall around it.

This is the City-State of Irisis.

The ground floor of the city is made mostly of shops, with the owner's house on the underground, because the city is very hot.

No building is allowed to have a second floor on Irisis, because everyone on the city must see the Sunspear (the golden obelisk) at any place of the huge city.

The city is ruled by a pharaoh-like governor, under divine right, that claims to be the Emperor of the Sun.

Arab-like cities grow throughout the desert, and all of them are submissive to the great sun empire.
