Yaai was a Carrack-class light cruiser belonging to the Rogue Grand Admiral Demetrius Zaarin.

The ship, along with EF76 Nebulon-B escort frigate Thinin and the Imperial-class Star Destroyer Glory was part of Zaarin's attempt to capture Missile Boats that Thrawn attempted to use as bait to trap Zaarin. However because the Immobilizer 418 cruiser Whirlwind was stalled by a surprise ambush the trap failed to pin down Zaarin. However the attempt to capture the missile boats had failed and among the losses Zaarin suffered were also his support Cruiser Yaai by Tan Maarek Stele.
