Menagerie is clearly implied as being a sort of reservation for the Faunus. I do not believe they were part of the four kingdoms, which are presumably human kingdoms. Unless we presume Menagerie is the Faunus ancestral home, it seems this was an area set up by the kingdoms for the purpose of keeping the Faunus well away from them. Perhaps it is a bit like a reservation in that the Faunus were being cleared out of their actual homes to make way for human expansion.
