How do you like the introduction of the Sith's red lightsabers being created by making an existing kyber crystal "bleed"? For years I just figured there was a planet the Sith went to that had red kyber crystals different from Ilum where the Jedi went.
Its certainly a dark and creepier concept, but I only question it because it requires them to take a crystal from a Jedi's lightsaber, which seems problematic depending on what Star Wars era you're in.
