I think there was a whole plethora of ghosts to choose from. England has an amazing past, a lot of heroes, a lot of very powerful and charismatic people, but we settled on the three ghosts that we chose because we felt like they had quirky sensibilities.

Boadicea was an amazing woman, she laid waste seventy thousand enemy soldiers with her army of Celts. Lord Admiral Nelson - he's missing an arm and an eye. How much more quirky can you get? And then [there's] Byron, our bisexual poet, who floats around reciting his poetry to anyone who will listen. He led an amazingly varied life and had affairs with all kinds of interesting people.

They were all very great people in their time, and it only stands to reason that they would be protectors of England.
