Actium
From Halopedia, the Halo wiki
Actium was a human colony world likely situated within the inner-confines of the Unified Earth Government's interstellar empire.
The colony was discovered by the Covenant empire in May 2545 and the proceeding Battle of Actium took place for less than a month, ending in the total destruction of nearby UNSC defences and the worlds inevitable glassing.[1]
