Borders always change. Tribes always change. Money always changes. Everything changes. Might as well embrace it...or you get left behind in a world which doesn't exist any more.

This is a snapshot of Britain at just one point in time, after the Roman occupation, after the angles, jutes and Saxons had invaded and settled these lands came the northmen, who eventually held all of "angl land" for a brief time, till the great grandson of Rollo, another northman, came and took over. That was in 1066. The rest is modern history.
