Denimoor was the Captain of the Venator-class Star Destroyer Tenacious during the early months of the Galactic Empire. He had previously served under then-Jedi General K'Kruhk during the Siege of Saleucami of the Clone Wars. Upon his return to the Tenacious, Denimoor received a holocall from Lieutenant Gregg, who inquired if any Jedi were involved in the Arkinnea incident. Denimoor casually denied the existence of Jedi on Arkinnea and Gregg appeared to accept his answer.
