Ahrbeg was named by the forces of the Fifth Expeditionary Fleet when they explored it in YE 29 when the Mishhuvurthyar conquered the Bard Cluster. It was then under the control of the Mishhuvurthyar until their defeat in YE 30. During this time, the Mishhuvurthyar committed total genocide of a native humanoid species called the Sangriat.
After the Mishhuvurthyar were driven off the system was once again under the control of the Yamatai Star Empire . The system was under the control of the Fourth Standard Fleet, and a colony was established primarily by former Yamatai Star Empire soldiers on the western coast of the primary landmass.
There are many sites visible from orbit where the Mishhuvurthyar were conducting massive logging operations, they are slowly being reclaimed by the environment.
In YE 32 the colony was expanded by an influx of colonists from the outer planets of the Bard Cluster. The Fourth Standard Fleet cannibalizing material and equipment from their damaged ships they created a fort on the planet and stationed soldiers on the planet. The Fourth Standard Fleet assisted the planet's colonists to develop Militias, they equipped them with obsolete/surplus equipment.
