Kylo Ren is the primary antagonist of the upcoming film Star Wars Episode VII: The Force Awakens. He is a member of the First Order and the Knights of Ren, and wields a unique crossguard lightsaber that he constructed himself.
The planet he appears on is too lush with trees for it to be Hoth, the world shown at the beginning of Star Wars V-The Empire Strikes Back. Kylo Ren is believed to be a Sith Inquisitor rather than a Dark Lord of Sith with a huge military base that Darth Vader had.
