The Aay'han was a DeepWater-class light freighter often used for joyriding. In 21 BBY, Kal Skirata purchased it second-hand from a Rodian in Calna Muun on Agamar for the price of 80,000 credits. He bought it because he wanted a craft with underwater capabilities to aid with his search for the Kaminoan scientist Ko Sai, as he believed that she was hiding on a water world.
