Map of the British Ilands

Beware: the contents of this article are not to be taken as official.

Explanations:

• Norwales (norþwalas) is an Old English term for who we today call the Welsh.
• Cornwales (cornwealas) is also from Old English. I arbitrarily decided to keep the -s for this map. I do not encourage this spelling elsewhere.
• East Engels as a term is similar to Wales because both derive from the plural forms of demonyms.
• Great Western Ocean is an attested name for the Atlantic.
• Welsc Sea uses the old definition of Welsh, which kind of meant "Celtic" long ago. Even Gauls were called Welsh at one point, like in the Old English term galwalas.
