"By the time we'd made our way to the molten surface of Mustafar, it was apparent that Delso had been a busy little bug. All by his lonesome, he'd found a previously hidden droid factory, fired it up and cranked out his own private army of battle droids. Needless to say, this got the men of the 501st...a little hot under the helmet, and not just because of all that lava. Truth be told, we'd all had our fill of those gearheads during the war. We couldn't stomach the thought of going through another one. So we blew them all up. Blew up the droids. Blew up the factory. Damn near blew up the planet."
