Honorary Britannians are Numbers who vow their loyalty to the Holy Britannian Empire. All non-Britannians living in Britannia-conquered Areas are allowed to accept honorary Britannian citizenship as long as they are willing to serve and be loyal to the Empire. Honorary Britannians are legally almost identical to ethnic Britannians: they are allowed to earn special privileges, live in wealthy cities, etc. Socially, however, they are frequently discriminated against on the basis of their racial background. Those who don't wish to serve the Empire become Numbers, and are both barred from living in wealthy cities and face legal discrimination.
