Sessoine, Siesia, Soissie, Sosie, Suize
A valley and town in northern France, about fifty miles northeast of Paris. Also known as a kingdom ruled by Clothair before he became King of all the Franks.
In the Arthurian legends, it is the site of the final battle between Arthur and Lucius, Procurator or Emperor of Rome. Arthur learned of Lucius’s advance through the valley and was waiting with his army. An epic battle ensued, in which many knights and kings, on both sides, were slain. Lucius himself was killed, and Arthur’s forces were victorious.
