Igdras system

The Igdras system, known to the Covenant as the Illa system, is a planetary system within the Polona sector of the Milky Way galaxy. The system has at least one planet, a human Outer Colony called Etalan. Etalan was attacked and glassed by the Covenant in early 2526, and it saw another engagement a few weeks later when a detachment from UNSC Navy's Task Force Yama targeted logistics vessels left behind by the Fleet of Inexorable Obedience.
