The first time the warship was seen was in The Kur Stone part 2, when he uses it to persue the Saturday's to their piece of the Kur Stone. In Van Rook's Apprentice he lets Van Rook use it, though it is nearly destroyed. In The Atlas Pin, Argost uses the Warship in order to fly around the world with the Naga relic looking for Kur. When the Saturdays' Airship finds it, Munya shoots missile at them, and the airship barely dodges them. Doc has to use his new jet called the Griffin to attack back. After losing the fight, Argost decides to go home after losing the Naga relic to Fiskerton.
