Star Wars: Episode III – Revenge of the Sith state to fight a Sith Lord. These are a few examples of many descriptions of characters' feelings and inner narrative. There are even some humorous lines added in, including extra dialogue in the battle between Grievous and Obi Wan - Grievous says, "I was trained by Count Dooku," and Obi-Wan replies, "What a coincidence; I trained the man who killed him." An official prequel novel, "Labyrinth of Evil" () by James Luceno, was published in 2005. It is set near the end of the Clone Wars and directly before the events of "Star Wars: Episode III Revenge of the Sith".
