Viento

Viento was a Human male politician who served as a senator in the Galactic Senate.

Both before and during the Clone Wars, he proved himself a valuable agent of Palpatine, both in his public personna as the Supreme Chancellor and his alter-ego of Darth Sidious, while also using both the Galactic Republic and the Confederacy of Independent Systems to achieve his own goals.

At the Dark Lord of the Sith's orders, Viento and Dark Acolyte Sora Bulq orchestrated the assassination of former Supreme Chancellor Finis Valorum, who voiced his intention of thrawting Sidious' plans.

However, Senator Viento's playing of both sides and double-crossings would prove his downfall, as Darth Tyranus - Sidious' Sith apprentice - moved Quinlan Vos into silencing him.

The Red Guard
In 32 BBY, Senator Viento was present during an assassination attempt against Supreme Chancellor Palpatine on Coruscant. Palpatine was saved by the Jedi Master Ronhar Kim. As the assassins had been disguised as Senate Guards, Viento suggested a personal guard be made for the Chancellor's own protection, resulting in the creation of the crimson-robed Red Guard.

Clone Wars
During the Clone Wars, Viento continued to do the bidding of Darth Sidious - Palpatine's alter-ego (though it is unknown if the representative was aware of this) - and supported the Galactic Republic. Despite this, he secretly aligned himself with the Confederacy of Independent Systems, planning to sabotage many the speeders of many Loyalist Commitee senators.

Upon Sidious' orders, he also helped arrange for Finis Valorum's assassination, a plot which also involved fallen Jedi Master-turned Dark Acolyte Sora Bulq and Anzati assassin Sajé Tasha. During this time, Viento had been placed under the protection of Jedi Master K'Kruhk.

He was assassinated in 22 BBY by Quinlan Vos, a Jedi undercover within the Dark Acolytes, who believed him to be Darth Sidious, the Sith Lord whom Darth Tyranus - the Dark Lord's apprentice - had mentioned to Jedi Master Obi-Wan Kenobi on Geonosis. Vos had misinterpreted Tyranus, who wanted Viento dead for his playing of both sides and attempt to double-cross him.
