The Seven Satrapies are not only the official name of the Chromerian Empire, but also the name for the seven semi-autonomous nations that make up the setting for the Lightbringer Series. Each surrounding the Cerulean Sea they have their own considerable amount of independence though they still serve and remain under the loose control of the Chromeria, the central government. Each Satrapy is ruled by a Satrap. The absolute rule of the land though subject only to the power of the Chromeria. Each Satrapy has a representative on the Spectrum, called a Colour, who not only represents his/her Satrapy, but also the colour that he/she is designated. In theory, the Colours are supposed to obey the orders of his/her Satrap, but this is not always the case. More often than not, the Colours become co-Satraps (in all but name) with the official Satraps.
