O script WGA diz isso:
She turns to look -- we PIVOT -- and see a BURNING TEMPLE AT NIGHT. We PAN to:
R2-D2 -- who watches the flames -- and a MAN appears (LUKE, whose face we do not see). He falls to his knees, reaches out to the droid -- with a MECHANICAL RIGHT HAND. We PUSH IN ON REY as RAIN BEGINS -- and DAY TURNS TO NIGHT -- and she LOOKS UP -- we TILT UP --
Note que o Templo em chamas está em uma cena anterior, antes de Luke e R2D2 aparecerem e definitivamente antes do KoR.
To see we're LOOKING UP AT A WARRIOR as he is STABBED BY A FIERY LIGHTSABER! He screams and falls to the ground -- we FOLLOW HIM, revealing Rey again, now in a nighttime battlefield. She gets to her feet, frightened by what she sees.
We PIVOT AROUND HER to REVEAL KYLO REN, and the six other KNIGHTS OF REN, who flank him!
Em outras palavras, o script não diz nada útil sobre o histórico do KoR. Mas parece que não é provavelmente o templo destruído de Luke.
Curiosamente, a novelização de Foster inverteu a ordem e menciona o SOME Temple como pano de fundo. Não faço ideia se era o templo de Lucas; mas Luke e R2D2 estavam em uma próxima cena SEPARADA no livro.
Day became night, sky ominous and filled with rain, cold and chilling to the bone. She was standing, she was sitting, she was looking up—to see someone, a warrior, take the full force of the lightsaber. He screamed and fell.
Battlefield then, all around her. Putting a hand to her mouth, she rose and turned. As she turned, she found herself confronted by seven tall, cloaked figures, dark and foreboding, all armed. Soaked and shivering, she stumbled backward, turning as she half fell. Firelight illuminated her, firelight from a distant, burning temple.
The seven vanished. A sound made her turn, and she blinked in surprise at the sight of a small blue-and-silver R2 unit.
