Kylo Ren is infamous. He is known for being destructive, selfish, sadistic, and in some circles: respected. Regardless of his reputation, he happens to be the religious Sith Empire's most loyal knight. With his status and his devotion to the higher...
Loyal didn't apply to who he was when it came to any situation other than his devotion to the Empire and the Force.
Serving as the Sith Empire's knight was all he'd ever known and all he ever considered wanting.
He had nothing besides the Emperor's high opinion of him.
It was the reason he was such a perfect knight. Kylo loved fighting and defending. He would often seek out trouble for the sole purpose that he wanted to be the one to put a stop to it. He enjoyed the struggle of it all; the injuries, the high stakes, and the promise of danger.
Kylo had no land, no belongings, no friends, and recently no family.
All he owned was his strength and ability to use his abilities to take down whoever might get in his way.
