The Tenacious, a Venator-class Star Destroyer, saw service during the initial period of the Galactic Empire. Captain Denimoor held the position of its commanding officer.
Against regulations, the Tenacious was rerouted towards Arkinnea with the purpose of assisting Jedi Master K'Kruhk and the younglings in his care. This intervention was made possible by Teron, an Imperial officer stationed on the planet, who extended this favor due to his and Denimoor's shared past serving under the Whiphid Jedi Master during the Siege of Saleucami.
