In Legends storylines, the Imperial Knights' primary signifier is their white lightsabers. However, the lightsaber has been recorded as being so rare in the current canon that the only acknowledged and the recorded user is former Jedi Padawan Ashoka Tano. Now you know more about white lightsabers! Hopefully, some more nuanced characters like the Imperial Knights will be adapted for media or even the story arc of Star Wars: Legacy. Either way, the white lightsaber and its wielder are among the more exciting developments in how we classify Force-wielders.
