Viento was a Human male senator who served in the Galactic Senate of the Republic during the Clone Wars.
Senator Viento was present during an assassination attempt against Supreme Chancellor Palpatine on Coruscant. Palpatine was saved by Jedi Master Ronhar Kim. As the assassins had been disguised as Senate Guards, Viento suggested a personal guard be created for the Chancellor's protection.
During the Clone Wars, Viento secretly aligned himself with the Confederacy of Independent Systems, and planned to sabotage many Loyalist senators' speeders. He also helped arrange for Finis Valorum's assassination, a plot which also involved fallen Jedi Master 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 Count Dooku had mentioned to Obi-Wan Kenobi on Geonosis. Vos had misinterpreted Dooku, who wanted Viento dead for attempting to double-cross him.
After his death, Viento was frozen in carbonite and placed in the Senatorial Tombs.
