Asźod was a barren, unpopulated territory on the continent of Eposz on Reach. The territory was home to several industrial facilities, including a ship-breaking facility, where the UNSC Pillar of Autumn was dry-docked on August 30, 2552 during the Fall of Reach.
During the final stages of the battle, Asźod was the only off-planet extraction point left on the continent. It was the site of the Battle of Asźod, where Emile-A239 died and SPARTAN-B312 made a last stand after successfully delivering a fragment of Cortana to Pillar of Autumn. The Spartan-III stayed behind to defend Autumn from a massive Covenant air assault including by a Covenant CCS-class battlecruiser. He was killed in action elsewhere in the territory, having been overwhelmed by Covenant infantry.
Other than the ship-breaking yards, Asźod also appeared to be used for transport of natural resources, evident by large pipe-lines spreading across the landscape. A small set of warehouses in between two gas pipes was where many dead Spartans were found.
