Born on the planet Kooriva, Denaria Kee was a Koorivar female who became a high-ranking member of the Corporate Alliance. She was chosen to act as and personal assistant to the head of the Alliance, fellow Koorivar Magistrate Passel Argente, as he was unwilling to trust his business dealings and illegal enterprises to a member of any other species. As an aide, Kee was responsible for writing drafts, sending covert messages, and managing Argente's meetings.
During the Separatist Crisis in 22 BBY, in which former Jedi Count Dooku led a faction seeking to break away from the Galactic Republic Argente and Kee attended a secret summit led by Dooku in the Stalgasin hive on the planet Geonosis. Kee stood near the Techno Union Foreman Wat Tambor during the summit as the various corporate leaders in attendance pledged their loyalty to Dooku. Argente committed the Alliance to Dooku's cause without hesitation, giving up his position as senator for the Alliance in the Republic's Senate. Having learned of the summit from the Jedi Knight Obi-Wan Kenobi, who had been spying on the meeting, the Republic arrived on Geonosis soon after and battle broke out between the Republic and the Separatists, marking the start of the Clone Wars.
Denaria Kee was killed by Darth Vader on Mustafar.
During the Clone Wars, Argente served as a member of the Separatist Council and, in 19 BBY, Kee accompanied Argente to the Klegger Corp Mining Facility on the planet Mustafar when the council was transferred there from the planet Utapau during a Republic attack. She was stood at a console on the walls of the facility's boardroom when Darth Sidious, true leader of the Separatists, contacted the council via hologram and told them to await the arrival of his apprentice, Darth Vader.
Believing everything was going as planned in the war, the council members were caught unprepared when Vader attacked them upon his arrival on Mustafar. Having been ordered to wipe out the council by Sidious, Vader killed everyone in the room, driving his lightsaber through Kee's chest shortly before he cut down Argente.
