Notes

• The term "Queen of England" is often used erroneously to refer to the Queen of the United Kingdom, as Wikipedia explains.
• The thinking by James Roberts is that by Nominus Prime’s time, the Primes had become like the Queen: a constitutional leader but with the government having more of the power.
