We already know that lightsabers are created from the rare, force-attuned Kyber crystals, which are rumoured to play in important part in the plot of Rogue One: A Star Wars Story due to their usage in the building of the Death Star’s superweapon; with previous explanations suggesting the red colour of dark side lightsabers came from artificial rather than naturally occurring kyber crystals.
Look, we all know the real reason the lightsabers are coloured the way they are in Star Wars: bad people get red lightsabers, and good people get blue or green – or purple if you’re Samuel L. Jackson.
Rogue One: A Star Wars Story hits UK cinemas 16 December.
Enter one of the many spin-off novels; this one specifically focusing on the popular Clone Wars and Star Wars Rebels character Ahsoka Tano, simply titled Ahsoka and penned by E.K. Johnston.
