This morning while driving into work, listening to Catalyst Audio Book, the end of chapter 12 . . . it's the end of the Clone Wars, the Jedi have been "disbanded", and Krennic shows Galen a case FULL of Kyber Crystals, Lyra then commented "you know where these came from . . . the size, the shape . . . these could only have come from Jedi lightsabers" . . .
