My Black Guard are all fairly powerful Dark Jedi with lightsabers and high-impact armour with a Cortosis weave to protect against lightsaber attacks. They were trained by Darth Nerd personally. He started with a group of 100 Force-sensitive children and trained them rigorously until only 6 remained and they became his guard.
Darth Nerd was sitting on the bridge of his Super Star Destroyer, The Exanimus, eating bacon and watching the crew scurry around below him when suddenly the enormous ship gave a lurch and dropped out of Hyperspace.
"What in the hell is going on!?" Nerd yelled at the admiral of his fleet, a Twi'lek named Chell, who was standing below him on the bridge. A small blue-green planet could be seen ahead of them. The viewscreens enlarged the planet showing a large crater in the main landmass that had obviously just happened recently.
"I'm sorry my Lord it seems something has pulled us out of Hyperspace. The rest of the fleet is nowhere in sight though and our communications aren't working. We have no idea what is going on. The only thing nearby is that small planet ahead of us," Chell said wringing his hands nervously.
"Well then find out what happened. I will need a contingent of troopers and droids. I'm taking a trip to the surface of that planet. Perhaps something down there is keeping us in normal space. You are in charge while I am gone. Try to find out where the rest of the fleet is and get them back here. I sense something through the Force. A deep evil even more ancient than the Dark Side. It seems to be coming from that planet," Darth Nerd said. He then spun on his heel with his cloak flaring behind him over his battered red and black Mandalorian armour. As he left the bridge his personal guard filed out behind him. They were dressed in uniforms nearly identical to those worn by the Imperial Guards under that fool Palpatine but Nerd's guards wore black as opposed to red. They also all carried lightsabers and were Dark Jedi personally trained by Nerd though not nearly as powerful and none worthy of becoming his true apprentice.
Nerd stopped by his room and grabbed his helmet as well as his blaster and extra lightsaber. It never hurt to be prepared. He then headed for the hanger bay. When he arrived a platoon each of droids and clone troopers stood ready for departure. They had only to board the ships behind them and they could be off. Nerd signaled for them to do so then leaped into the cockpit of his own modified, red X-Wing starfighter. The six members of his guard all climbed into their own black X-Wings then the ships all lifted off and headed for the planet.
