Action at Mustafar

The action at Mustafar was a naval engagement four years before the Battle of Yavin when the Spectres staged a mission to rescue the Jedi Kanan Jarrus, their co-leader who had been captured during a mission to infiltrate the Imperial Communications Center at Jalath. With the help of the Devaronian crime lord Cikatro Vizago, the rebels sent Chopper to infiltrate an Arquitens-class command cruiser in order to find Jarrus' location. They discovered that Jarrus was being transported to the Mustafar system aboard Grand Moff Wilhuff Tarkin's flagship Sovereign.

Using a stolen Gozanti-class cruiser, the rebels managed to infiltrate the Sovereign and used detonators to unleash a massive electro-magnetic pulse that disabled the Star Destroyer. Jarrus' Jedi apprentice Ezra Bridger then freed his master. While escaping the ship, Jarrus defeated the Grand Inquisitor in a duel which damaged the Star Destroyer's reactor core; setting of a chain-reaction which destroyed the Star Destroyer.

The Spectres managed to escape the stricken vessel before it exploded but were pursued by several TIE fighters. Several rebel ships from Phoenix Cell arrived and rescued them. Following Jarrus' rescue, the rebels met the former Jedi Ahsoka Tano and learned that they were part of a greater rebellion. For the rebels, the skirmish marked one of their earliest victories in the Galactic Civil War, as well as an escalation of rebellious activity in the Outer Rim Territories.
