The Spectral Guardians were spirits that guarded the Jedi Monument on Rhen Var. During his search for Ulic Qel-Droma in the Dark Reaper Crisis, Anakin Skywalker encountered them protecting Ulic's tomb. Not allowing him to enter, Skywalker was forced to battle them in a TX-130 Saber-class fighter tank. He managed to dissipate them by destroying their tombs, which their powers were tied to. He then proceeded to retrieve the information he sought. They attacked with various wind projectile and beam attacks.
