TFA - 15 - Room to Rubble

In the center, the single coppery-hued, angled bench stood empty, its multiple curving restraints open and mocking beneath the subdued red illumination from the ceiling. Unable to contain himself any longer, he pulled his lightsaber, thumbed it to life, and launched into a series of wild swings and strikes, methodically reducing the room to rubble.

Hearing his howls of outrage, a pair of stormtroopers crossing at the far end of the access hallway changed course to investigate. What they saw within the cell as bits and pieces of red-hot debris came flying out caused them to retreat the way they had come—fast.
