The sea is the world; there is no land; there is no bottom; if you go deep enough you come out on the other side. There’s stuff floating on the sea – ice and seaweed – but mostly there’s just sea and above it there’s just air. Without anything to interrupt it, the Coriolis Effect drives severe weather patterns that are as predictable as the sunrise – winds and currents are strong, the surface generally is tumultuous, and there’s a tremendous amount of rain. The poles are covered in massive, thick, permanent ice. The ice in turn is surrounded by pack ice. Bergs drift around.
