An Imperial garrison commanded by Captain Junus was stationed on the planet Mustafar during the reign of the Galactic Empire. The garrison was present on the Gahenn plains when the Sith Lord Darth Vader was overseeing the construction of his castle.
Some time after Vader's castle was completed, the garrison engaged with an overwhelming force of native Mustafarians and lava fleas. Darth Vader himself assisted in the defense of his fortress, but the entire garrison was wiped out when the Mustafarian Father Kkkt used the the Force to summon a massive wave of lava that flooded all of the surrounding landscape. Darth Vader was the only survivor of the attack.
