Once upon a time, a Sidhe decided there needed to be some structure. He went around and made himself the High King and installed or met others as just… normal kings that listened to him. High King Brion and his advisors, King of the Fairies, etc.
Now, there is only one king, everyone else just a lord of something. Lord of Fairies, etc.
Among the Sidhe, there are also clans. This will be expanded on in the Sidhe specific page.
King and Queen, lords and lieges.
