As the Senators of the Republic discussed the conflict, Senator Valorum proposed that a meeting take place between the Stark Commercial Combine and a combination of Jedi, Republic, and Trade Federation representatives. Tyvokka was asked by the Republic to be chief negotiator. Tyvokka gladly accepted the position and asked Plo Koon to be his aide in the matter. In a meeting with Senator Valorum and other Jedi Masters, Tyvokka spoke his uncertainty of the bacta shortage, and suggested that Jedi Master Tholme and his Padawan Quinlan Vos travel to Thyferra, the planet on which an apparent disaster was the catalyst for the shortage, to discover the truth.
The conference was to take place in a secret location known only to the visiting parties, and the location that was chosen was the planet of Troiken. Other Jedi Knights to accompany Tyvokka were Qui-Gon Jinn and his apprentice, Obi-Wan Kenobi, as well as Jedi Master Adi Gallia. When the meeting began, elsewhere in the galaxy, a bellicose Senator, Ranulph Tarkin, who strongly advocated the establishment of a legitimate Republic Army and Navy was preparing to launch into hyperspace to surprise Stark and his forces and finally utterly defeating them. Although the location of the meeting was to be secret, Tarkin obtained the location through secret dealings with a Trade Federation representative.
Unfortuantely, Stark learned of this, and believing the conference was just a trap to capture him, Stark took the initiative to set a trap for the Jedi, the Senators, and Tarkin as well. Once the meeting began, Stark ambushed the Jedi with a company of soldiers armed with powerful weapons and revealed to the Jedi and Senators his plan to deal with Tarkin's fleet. Creating a computer virus that infected all Republic ships, Tarkin's fleet was scattered across the galaxy once they entered hyperspace, some sent into planets, stars, black holes, and some right into the middle of Stark's own fleet to be decimated. However, Tyvokka believed and was able to get Stark to admit that the whole thing was a trap from the beginning, a trap in order to gain power.
Feeling he had the Jedi surrounded, Stark offered the Jedi a chance to surrender since he felt they had no other choice. But to a Jedi Master, there is always another choice. Literally turning the conference table upside down on Stark and his soldiers, the Jedi ignited their lightsabers and began to fight their way out of the trap. Additionally, the Trade Federation representative demanded he be allowed to bring along a number of battle droids for protection, and during the melee activated the droids and instructed them to attack. However, as battle droids are unreliable, they attacked not only Stark's soldiers, but the Jedi were targets as well. Sadly, in the chaos of it all, Tyvokka was hit multiple, multiple times by blasts from the battle droids.
