Watt Tambor - Star Wars: Episode III Revenge of the Sith

With the death of Count Dooku aboard the Invisible Hand, General Grievous ordered Watt Tambor and the rest of the Separatist Council to be sent to the planet of Utapau in the Outer Rim of the Galaxy. As it was a neutral world, it would be the last place the Republic would think to look. 

At least that was the intention. Nevertheless, the Grand Army would track Grievous and his forces to the planet, but not before Tambor and the rest were once again moved, this time to the planet Mustafar.

The stronghold, the headquarters of Klegger Corp Mining Facility was a Techno Union-owned structure, designed to keep them safe and secure until the end of the war. The planet also had trade dealings with Watt Tambor and Techno Union, in exchange for Separestist support. 

Receiving word that Grevious was dead, Tambor and the others waited for the arrival of Darth Sidious' new apprentice, Darth Vader. There they would peacefully surrender and end the three-year-long war between the Republic and the Separatists. 

Or so he had thought. 

Vader's arrival did indeed mark the end of the war, but not quite how they imagined. The Sith apprentice proceeded to slaughter the members of the council one by one. Tambor tried to flee, but he was impaled in the conference room. 

With his death, the Clone Wars were deemed officially over. His assets would be seized by the Empire and those loyal to him, executed as war criminals and traitors.
