Ghostfire crystal

Ghostfire crystals were transparent kyber crystals found on mountain peaks on a handful of Outer Rim Territories planets. Ghostfire crystals were incredibly difficult to find, and when found, made the lightsaber they were used in nearly silent, as well as the lightsaber's blade dim and translucent. Ghostfire crystals also had the property that they would produce afterimages that followed the wielder's motions, causing a target to become disoriented.
