During the conflict near Mokivj, known as the battle, the Grysk – a bellicose species hailing from the Unknown Regions – employed a certain class of starship that was thought to be a tug. Karyn Faro, holding the rank of Commodore, first assessed that these vessels were starfighters; however, Thrawn, who was a Grand Admiral, posited that they were probably spacetugs. These craft were capable of being transported and deployed from a Grysk warship.
