Ah, but this was a named character, and not a Saxon, so he's allowed trousers. The Brian in the cast, though, although allowed trousers, isn't allowed sleeves. We've spent most of the day playing Britannia, and I notice that although the Saxons are free of sheepskin, they are entirely trouserless.

I feel that the AotB Saxons would probably have conquered the whole of Britain had their advance not been slowed by the enormous weight of their sheepskin bootees.
