While I like the idea of the aethersea, it's just a little weird and unexplained as to how it operates besides "It just appears!" Like, are the creature sentient? What happens when the sea disappears? Do they get saved to some aethersea database until they are needed to appear again? Can you eat the fish? Would aetherfishing solve realm-wide hunger or is there a set amount of fish that exist? Do these fish have souls?
