Satraps in The Seven Satrapies are leaders of their respected satrapies. The female equivalent title is Satrapah. Satraps/Satrapahs are responsible for appointing Colours to serve on the Spectrum, the governing body of the whole empire, and in theory the Colours are supposed to follow the orders of their Satraps/Satrapahs. In reality however, the Colours often become unofficial con-Satraps/Satrapahs.
Notes:The name "Satrap" was based on an ancient Persian title, which meant a leader of one province.
