So, on a large (20-25 000 km^2) island, there is a lake, and in middle of that lake is a small lake-island, where there is a city of 9 thousand Skrits. These poor folks built their city on top of a magical "dungeon", a self-contained large magical space, filled, and more importantly, magically refilled with berries and prey animals every single day. Skrit are a fallen magical civilization, who due to divine curse not only lost their magic, but also had almost 90% of adult population die off in a matter of a single year around seven centuries ago...
Long story short, their society collapsed, most of their herritage was burried deeper in the dungeon where their original city was located, and magicless Skrit can't really access those ruins. They lost most of their former knowledge and became equivalent of mere early civilizations(5000-3000 BCE). Their clothes - intricate, but made of animal skins, with wooden and copper ornaments. Their tools and weapons - mostly stone, wood, and copper. Their houses - built of mudbricks and wood.
But compared to those civilizations of Earth, they still had a massive advantage - a dungeon - magical source of food that allowed them to only need 40-60% of dedicated adult population to feed the entire city. In the end, around 85-95% actually participates in hunting at least occasionally, but only 40% of people are full-time hunters. It is obvious that there will be some manufacturing jobs, but if I remember, most preindustrial civilizations needed 80-90% of people to be food makers, and had to do with only 10-20% of manufacturers, government officials, artists, teachers etc.
So, my question is, with so many free hands, how would leaders of my city put those unused hands to use?
