Kylo Ren's upsilon-class command shuttle soared through the ash filled sky of planet Mustafar. The Knights of Ren, which he had been a part of many years ago, had found a map that led to his grandfather's castle. It belonged to Darth Vader, and as his self proclaimed heir, it now belonged to him.
This wasn't the first time Kylo had been to Vader's castle, however. Over the last few years, he had been visiting frequently. There is a cave just beneath the volcanic surface that the castle was built on, and it's strong in the dark side. It called to his grandfather, and now, he believes it calls to him.
Vader's castle had become more of a church for the knights of ren, who worshiped the dark side. They believed that the Jedi and Sith waged war with eachother in the afterlife. Dark versus light in a never ending struggle to maintain balance in the force by battling in the spirit realm. They would scour the galaxy to find sith relics, and destroy them. They believed that if they destroyed the ancient artifacts of the sith, that the sith lords would then be able to use them in the afterlife.
As the offspring of Lord Vader, Kylo Ren is seen as their patriarch. He is undeniable proof that to this day... 'Vader lives'
The knights called Kylo to Mustafar to present them with something they had discovered. It was something that they decided he deserved to have before it was destroyed so that Vader could use it in death. Vader's heir deserved to have it as he shaped the galaxy as he saw fit, and finished the dark lord's quest.
The Supreme Leader's ship touched down on the landing pad of the castle. He stepped down the landing ramp as it unfolded, the smoke from the volcanic world parting as the ramp touched down against the hot metal surface. Kylo walked straight towards the castle's gate, his chat with Anakin Skywalker only fueling his drive to finish Vader's destiny. No. His destiny.
Where Anakin Skywalker proved compassionate, he would be merciless. Where Anakin had been conflicted, he felt resolve. This galaxy would be his, in the name of his bloodline.
As Kylo stepped into the throne room, there was a semi-circle consisting of six hooded figures. The six Knights of Ren, standing in front of the throne.
One of the knights stepped into the center and knelt down as Kylo approached. The Knight lifted up a small jewel box with both of his hands, presenting it to their leader.
Kylo reached down and unlatched the box, and slowly lifted the upper half. Sitting atop a red silk pillow, sat a deep red kyber crystal. The darkness surrounding the crystal was infectious, permeating the air like a rotting animal. The feeling was contagious. Kylo and every knight could feel the air thickening, growing dense with evil.
It was Lord Vader's kyber crystal. The very same one he used to wreak havoc across the galaxy all those years ago. And now, it belonged to Kylo Ren. With a piece of his grandfather's weapon, he would fuse this crystal with his own Lightsaber and complete his destiny. Thousands more will die in the name of Vader's bloodline, and he would stop at nothing to see this conquest to it's end.
Kylo picked up the crystal, his followers staring in awe as he took the priceless heirloom. A wicked grin crawled across his lips as he held it in the palm of his hand. This was the beginning of the end.
