An endless expanse of water that meets the City through the Harbors. As with the Forest, it has not been explored intensely, as anyone going beyond the curvature of the horizon never came back. Its abyssal depths seem to hold only things that despise whatever comes from the surface and information about it is scarce. Where the Sea meets land near the Suburbs, it creates a lovely beach that's usually full of unaware people enjoying endless Summer. When it meets with the Forest, it creates a fjord. Going further along this fjord also counts as going beyond the curvature of the horizon for the purpose of disappearing forever.
