So, I'll start with a short summary:
I wanted to have magic world with other-than-agriculture based civilization. I gave them magic dungeons. I'm afraid that there are many problems I didn't take in account.
My situation is this:
In a fantasy world with magic [but no RPG levels stuff], there are multitude of magic dungeons spread across the land - some of them smaller and single leveled, some of them larger and even multileveled. These dungeons, rather than existing within the ground exist outside of space, connected to the world in small entrance only. Their entrance is only open for 5 days, then they need to "recover" and close - it is inadvisable to stay trapped in dungeon for the closing period, but it has been done(animals inside go madly attack any tresspasser within). Recovery time is 40-20 days for level 1 dungeons, 20-10 days for level 2 dungeons, 10-5 days for level 3 and higher dungeons. [EDIT: THE DUNGEON EACH HAS ITS OWN REGULAR CYCLE - THE AMOUNT OF DAYS NEEDED TO RECOVER IS STATIC. There's usually short (20-50 m long) "corridor" between levels, this "corridor" is usually over 10 m wide. The dungeon contain "sunlike" shining ilusion in the "sky", sky being usually 60-200 m above the ground
There's around 1 dungeon per 100 km squared area on average:
- Of those, 90% are "minimalistic" dungeons - 1 level, area of 1-10 km^2,
- 9% are slightly larger, area of 10-20 km^2, but still only 1 level
- 0.9% are 2 leveled, 20-40 km^2 for first level, 1-20 km^2 for second level,
- 0.09% are 3 leveled, 40-60 km^2 for first level, 20-40 km^2 for second level, 1-20km^2 for third level.
- 0.0099% are 4 leveled, 60-80 km^2 for first level, 40-60 km^2 for second level, 20-40km^2 for third level, 1-20km^2 for fourth level.
- 0.0001% are 5 leveled, 80-100 km^2 for first level, 60-80 km^2 for second level, 40-60km^2 for third level 20-40 km^2 for fourth level, 1-20km^2 for fifth level.
All single-leveled dungeons are forest-food sources. They contain berry bushes, they contain other food source plants -not bred, but still magically gentically modified to provide larger fruits/roots with more sustenance, game animals and they contain twice to three times as much of it than natural forest would.
For level 2 dungeons, their first level contains food-forest, while other levels may contain anything from more forest to rare metal "surface" mines, magic stone deposits, or even monsters. Some of smaller level 3 dungeons follow this scheme, but bigger they're more often they instead become themed dungeons where levels are similar and deposits or forests may or may not be sprinkled across levels freely, which continues on for 4 and higher leveled dungeons.
Information almost unrelated to the question:
Level 4 and level 5 dungeons sometimes spawn new forms of life, sometimes even with human-level intelligence and sentient. Level 5 dungeons are connected to endlessly growing "magic plane", which is a peaceful plane of existence full of magic energy, that however isn't good for anyone to stay in - while short term exposion to strong magic within is beneficial, long term causes first discomfort, and later on growing paint that by the time you spent a year in it becomes torturous. However, the "magic plain" contains road network, connecting level 5 dungeons on same planet as well as connects those to level 5 dungeons on relatively nearby planets.
My understanding of their societies - Presence of level 2 and smaller level 3 dungeons filled with food can lead to formation of sedentary societies. Some areas contain more of these dungeons, but some contain mostly level 1 dungeons which favour more nomadic lifestyle instead. However, many places would have enough level 2 dungeons to start sedentary civilizations.
Sedentary: Towns would have hunter/warrior class "diving" into dungeons to feed their families. Cities would usually be placed on dungeons, but probably depend far more on trade routes than on their own dungeons. Villages that former around level 1 dungeons in city-dominated societies would usually hunter gather in nearby areas, herd animals or partake in fishing if they were near a water source, and rarely partake in some proto-agriculture(never really fully developing it), while dungeon was closed. Except for some specialized developed level 3+ dungeons, dungeons with mines usually yielded only very small amount of metals upon each recovery, and eventually, societies discovered that mining in mountainous regions provided more ores. [Iron wasn't used, because it was cursed, so bronze all the way].
So my question is, what would be the differences be for societies developed in such an environment where instead of agriculture, there was means of sedentary hunter-gathering, centred on level 2 and smaller level 3 dungeons[as well as odd and rare forest-themed level 4/5 dungeons]?
