Star Wars Galaxies: Trials of Obi-Wan was the third expansion pack for the MMO Star Wars Galaxies. This expansion added the ground planet of Mustafar to the game, and was designed to capitalize on the DVD release of Star Wars: Episode III Revenge of the Sith and its final fight sequence between Darth Vader and Obi-Wan Kenobi, which was set on the same planet. Trials of Obi-Wan includes more than 50 new quests, from rescue missions to the exploration of a crashed Republic cruiser. Many quests also revolve around the return of HK-47 from Star Wars: Knights of the Old Republic, whom players can kill for a quest. The expansion also allows players to interact with the ghost of Obi-Wan Kenobi to help him "correct an imbalance in the Force" present on Mustafar. High-level quest rewards include the ability to find a fiery red crystal found only on the volcanic planet that creates a lava-like lightsaber.
