Llech Las
A location in Scotland where Iddawg, one of Arthur’s warriors, performed penance after his lack of diplomacy caused the battle of Camlann.
Notes
Llech, signifies a flat stone, a flag, in Welsh. It probably refers to the Druidical circle stones. The English league probably derived from llech, where a league was a measure of distance marked by a stone standing on end.
