Metarchy

A metarchy was a vast network of Forerunner artificial intelligences composed mostly of ancillas and monitors, and was coordinated by a metarch-level ancilla. Most of the ancillas in a metarchy were disembodied and never assumed visible form. There were several significant metarchies, including the Council metarchy located at the capital and the metarchy used by the Librarian. The Council metarchy answered to the Forerunner chief councilor, and coordinated all operations within the capital, including its defense.
