Arzu was a moon orbiting the gas giant Palmyra in the KOI-2702 System of the Far Spinward Colonies. Originally the site of an Engineer outpost, Arzu was later conquered by the Fulfremmen and consumed by their living Proto-Hive. In 2186 a lifeboat from the UNCSS Typhoon, a vessel from the United Nations Interstellar Settlement Corps' Great Mother Mission, crashed on Arzu, triggering an incident.
