The Second Clone War (CWII), is set in an alternate timeline of the Star Wars universe. One in which the droid army was not deactivated by Darth Vader on Mustafar, but instead was allowed to persist. CWII follows the Legends timeline, but ignores The Clone Wars animated series from 2008. The timeline is exactly the same, however it diverges during the Battle of Utapau. When General Grievous is defeated by Obi Wan Kenobi, Grievous is revived by his personal protocol droid. The general is brought to a secret location, where the rest of the events of Revenge of the Sith play out as normal. After the duel on Mustafar between Obi Wan and Darth Vader, Grievous awakens in his castle on Kallee. He later learns of Sidious’ and Dooku’s deception, and vows to destroy the Empire. From there, he rallies the Sepratist holdouts under a unified banor: The Remnant. With this new threat, the Empire pushes forward with clone production growing the aging army’s ranks with fresh troops to fight the droids.
