The teaser sets the tone with its very first image: a twinkling starfield that’s soon revealed to be a patch of dirt on Luke’s remote island hideaway, in which grains of sand and rock catch the light. This is the place where the elder Jedi (Mark Hamill) is training his new protégé, Rey (Daisy Ridley), in the ways of the Force. We see her training with her blue lightsaber. We share her visions of “Light” – a shot of the late Carrie Fisher’s General Leia, her back to the camera in the Resistance command center; “Darkness” – the mask of her nemesis Kylo Ren (Adam Driver), shattered to pieces, with Darth Vader’s trademark heavy breathing in the background; and most intriguingly, “Balance” – a huge treelike chamber that we’ve never seen before, housing an empty platform, and a map with the symbol of the Jedi emblazoned on it. “It’s so much bigger,” Luke tells her, making it sound like the Star Wars Universe’s world-building is about to expand considerably.
