I just watched this video from Shadiversity about implications of monsters and magic in a fantasy setting. Ha said a lot about how society could be, but it makes me think: how can the society "kickstart" in a hostile environment?
Imagine this: a world full of animals and plants, with a ecosystem like ours, and monsters with no ecosystem at all, they just appear, destroy things, and live until the moment when some animal or other monster kills it, so they disappear. Humans and other intelligent beings live as hunter-gatherers.
So, how can those humans build settlements and develop, if large groups can be easily killed by monsters?
Note: Of course this have no right answer, I just want to imagine what do you think about the topic?
