One thing for sure about this series, it's succeeded at creating some truly strange characters/nations.
A colony of witches on the moon? Sure.
A country made up of one mother and her unborn children, using witches with stretched-out necks as some kind of fuel? Why not.
A medical country ruled by a genius doctor who delivers babies that go on to be the nurses he gropes and that inject him with vitality increasing fluid? But of course!
