Reigners

The Reigners, in the novel Hexwood are five beings who control our galaxy. They are the heads of the [House of Balance]?, which is one of a number of Houses, and live on a planet near the centre of the galaxy known as the Homeworld?. They have, to some extent, magical or supernatural powers, but appear human.

The Reigners are referred to by the numbers one to five, although Reigner One has a name and the rest presumably do as well.
