Plautopseum was an ancient member of the Jedi Order who had attained the rank of Master. Ancient accounts kept safe by the Order claimed that Plautopseum had passed into the Force upon dying and transcended death by returning as a phantom. Along with Masters Galong-Tal and Arca Jeth, Plautopseum's story was recovered by Luke Skywalker within a holocron following the Great Jedi Purge.
