The Ytha'ac Cluster was a cluster of asteroids in the Airam sector of the Outer Rim Territories at galactic coordinates M-20. It was located within the Ytha'ac system. During the Galactic Civil War, operatives of the Alliance to Restore the Republic were to meet with Airam smugglers who had stolen a stock of Imperial munitions. However, the Imperials had sent a strike force consisting of Assault Gunboats and Gamma-class ATR-6 assault transports to recover the pilfered supplies.
