In the south quadrant of the city, there are tall towers springing up from the squarish one to three story buildings normally found in the city. These "towers of poles" are a good fifty or sixty feet tall above the roof line below. They are made of wood or bamboo poles spliced together, sticking up from the buildings below. On these tall towers of wood live the BirdFolk and other flying peoples.
These towers are tall, light, and topped with small roofs. Some towers have some lateral supports made of the same light wood/ bamboo. The towers of poles are light and designed to sway in the winds, but if they do break they are so light that there will be little damage below.
Strung between the towers of poles are tents of sorts that act as rooms and apartments. These "tents" are usually inside the tower, but some are strung between towers. Off the towers the various folks hang colorful streamers and flags. In addition to general decoration, the flags are used to mark "addresses", neighborhoods, and "pathways".
The "people" live in "tents" of sorts strung between the rails and struts of the towers. Since all the various skyfolks have little in the way of personal possessions, there is little weight in these towers. The only heavy rooms are the few skyfolk temples there. They are not much more than larger and heavier canvas tents with a few built in alters and braziers.
There is a tower standing tall from the south district gate. That tower has only one thing, a large hoop. This hoop marks the gate to and from this quarter. It is manned at most times. There is a token drop there, so comings and goings can be measured and a district ledger kept. All the skyfolks are supposed to fly through the gate when they leave their quarter, so they can be in compliance with city law.
The skyfolks descend to the ground for the various other services they need.
