The North Sea is a fairly small sea in northern Europe. It is hemmed on three sides: by Foroned Kingdom in the west, Norway and Denmark in the east, and Belgland, the Netherlands and Theechland on the south. In the north it flows straight into the northern Atlantish Sea.
In times foregone, the sea was known as the Theedish Sea, but the name was shifted in the First World War so that nobody in England would think that in truth the Theech owned it.
