- ―Obi-Wan Kenobi and Block
Block was a fleet officer who held the rank of Admiral in the Republic Navy during the Clone Wars, serving aboard the Venator-class Star Destroyer Vigilance. Block provided air support for the Jedi Quinlan Vos, Obi-Wan Kenobi, and Anakin Skywalker during a mission to destroy the Separatist Vanqor listening post on Vanqor. However, Vos had secretly warned his master Count Dooku about the Jedi-Republic attack and the Separatists were able to evacuate the facility before Republic forces arrived.
