The Eternal Empire shuttle was an elaborate model of assault-shuttle designed like all Eternal Empire vessels for optimum speed and technology derived and engineered from Zakuul's Eternal Fleet.
The first instance of this vessel seen was during the Attack on Korriban in 3636 BBY when the Twin Princes Arcann and Thexan boarded one of these starships at the end of the carnage of the battle and then sped off through the dusty skies of Korriban and arrived at the Eternal Throne on Zakuul.
A specimen of the Eternal Empire shuttle was also spotted on Kira Carsen's Ship, during the battle that took place this specimen was used by the Scions of Zakuul to board the ship to resurrect Valkorion but were later wiped out by the fanatical Servants when both proceeded to fight over who had the best interpretation of the will of their master. This specimen was promptly ejected into the vacuum of space by the Outlander.
This particular model of shuttle also shared many striking similarities with the Eternal Empire Walker, also used by the Eternal Empire.
