Syxesteer was originally the king's residence; it developed into a town as trade with the Meťaiun and Caďinorians developed. The invading emperor Aiďoctodos burned the city to the ground in the 1290s, and it was also occupied by Sevurias in 1608, though much of the population simply melted away, forming a resistance army.
The city grew explosively under the last kings, who aggressively developed the Floran economy, building shipyards, factories, banks, and universities, but in a way that seemed to mostly benefit the royal family. The last king, Gennil (7et), was forced to abdicate by the Forujmory (the legislature) and Chendio, the high priest of Syxesteer (3215).
Syxtesteer is located on the northern coast of Flora, not far from the western end of the island; the climate is nearly always warm and pleasant; it is refreshed by many parks and gardens. Its population is over 125,000, so that it is the home to about 1 in 6 flaids. In "Jeerio tries to find a job" the city is described thus:
- Syxesteer was a very large city, with elaborate buildings painted blue or red or orange. The houses were tall, so that the street was in shadow; perhaps because of this, there were lanterns set on iron lampposts all along the street. Their road was colored red and the other streets were black, so that you could easily follow it without getting lost.
- The city was full of flaids— flaid children playing games or doing their homework or delivering newspapers, flaid adults watching the children, or riding horses, or buying things, or talking to each other about all sorts of things.
- 176 houses since the sign with the name of the city on it, they came to the downtown area. He and Jeerio had never so many stores, offices, and important-looking buildings. Businessmen, businesswomen,and businesschildren rushed by busily on business. Boys rode by on bicycles, or tricycles, or even quadricycles and quinticycles. Dogs rushed by after cats; cats ran by before dogs. There were even short, small-headed people with big clumping boots. Jeerio stared at them because he had never seen a human before.
Travelers often praise the color-coding of Syxesteer's streets; Jeerio's red street starts at the port and becomes the city's major north-south boulevard, continuing into the hills and across the island to Pickapo. There are two main east-west streets, the blue road along the water and the yellow road further in (which continues eastward to Tolgron). The colored streets are completed by two more north-south streets (green and brown) and the pink road which leads from the Forujmory to the Irrean temple.
Human travelers usually note the height of the buildings (flaids are taller than humans); the organic curved lines of traditional structures made of adobe; the many children (the city is quite safe, so children can freely wander the streets and parks); and idiosyncratic landmarks such as the Monument to the Logarithm.
