As we are now less than a month away from the anticipated premiere of Star Wars: The Last Jedi, Lucasfilm has unleashed a new teaser for the picture.

Here, we find Luke Skywalker training Rey, as she notices that there is something else out there in addition to the lightness and darkness, of course with the light being for the Jedi and the guardians, and the darkness for the Sith. And while we don't yet know what that something else is, Luke insists that Rey resist it.

Star Wars: The Last Jedi, which acts as the followup to 2015's Star Wars: The Force Awakens, is due in theaters December 15.
