And this is law I will maintain

[ewx]

You've probably heard of The Vicar Of Bray, a 17th century Berkshire churchman of rather flexible denomination. But there's also a region of France called the Pays de Bray which in the 12th century was on an important boundary in France.

A most vulnerable territory was the Vexin in the upper Seine Valley, often an invasion route for the Capetian forces striking from Paris towards Rouen. [...] Another typical lord of the Vexin was Hugh de Gournay, the dominant lord in the Pays de Bray, whose changeability won him a reputation as ‘a man of both sides’.

I'm left wondering if there's something about places called Bray that encourages famously negotiable loyalty?
