Megastructure world building

So there's this giant, self-replicating mega-structure about the size of a planet. Nobody knows why it exists or why it keeps extending itself. There's billions of human and post-human settlements on the millions of levels that now exist.

Please pick a numbered section and develop the culture and creatures that live there. Claim your section in your post. Keep in mind even the smallest section is still bigger then Manhattan island.

This particular section of the megastructure is suspended like a bridge over a massive drop, with more megastructure below. The white space inbetween the sections represents a steep drop to the levels far, far below.

Also I'm going to be storytiming blame! while we worldbuild, but I have a third world connection and will probably have to stop when the grid goes down

that's the conclusion of book 1, may storytime book 2 in a bit if there's any interest in megastructure settings and posthumanity

Claiming section 10. It's a city built into the walls and towers, and is connected by hundreds of crisscrossing bridges. It's a giant trade hub and even has some rudimentary manufacturing businesses, mostly clan owned. The big pull of section 10 aka Mauve City, is its fully functional water purifier. The residents of Mauve city attribute religious significance to the purifier, and even have a priest class dedicated to its upkeep

What type of setting is this? High fantasy gone wrong? Is there magic? Classic DnD monsters?

If so, I claim Section 6. It's primarily an agricultural zone that relies on the adjacent sections for protection. In exchange, the denizens of section 6 produce a surplus of food and trade it for other goods.

The primary crops are mushrooms, moss, worms, and dire rats. Over a few centuries of domestication of these creatures, the people of section 6 have altered them slightly to better suit their needs. The rats, while still massive, are less aggressive. Mushrooms grow to the size of trees under their guiding hands, and can even be cut and carved like wood once fully grown. The same mushrooms can be harvested early for food. The people there have even managed to domesticate some smaller varieties of giant spider, and use them as guard dogs.

They are famous, or perhaps infamous, for being uneducated bumpkins. However, their cooking skills are renowned for hundreds of miles around. No one can make rat and mushroom soup like a Section 6er.

the setting is actually sci fi, kind of. There's extremely advanced technology but most everyone has forgotten how to use it, so your section 6 idea works surprisingly well

and that's book 2! So far you can tell the story involves the "lone gunman" exploring different parts of the mega structure and the different cultures that pop up. It gets tits up from here, so ill def post more if more discussion happens. But for now it looks like we got

>Section 10, trade city/water religion
>Section 6, agricultural zone that pays tribute to surrounding sections

>randomly rains huge grubs
Going to steal that for a game.

part 3, in which we see some actual settlements

Section 13 is a series of cities surrounding a giant citadel. Inside the citidel is a man known as the alchemist. He has 3D printers and birthing vats. He only has schematics for Soviet T90 tanks, attack helicopters and armored transports, as well as a variety of small arms. He uses the vats to birth orcs. He considers himself a good man, and uses his orc armies to exterminate surrounding monster infestations

The alchemist is not the best administrator, and most of the surrounding city is self governing. He covets 3D military schematics so he can expand his forces

I'm claiming area 25, the furthest. Part an psychiatric asylum, part prison, part library, and part peregrination location.
Of all the near places, this one is the most dusty and most strange of all. The floors and walls are mostly covered in books ruined by mold and time. There's a huge hole in the ceiling, so this section is notoriously illuminated by natural light, but also extremely contaminated by the unfiltered air and eroded by the wind.
It's inhabitants wear the thickest clothes over their whole bodies to protect themselves from the wind, and are widely considered insane, and way too outsider and bizarre to even be considered pariahs. They speak in their own language. Most people suspect such language doesn't exist and they just shout random noises at eachother.
Other people (in the minority) suspect there's a sort of wisdom or great knowledge spoken between them, but few are willing to actually study their books and speak to this people.

Two new sections, the Alchemist City and the prison/asylum/library mega structure with a divergent and isolated culture
