The title of Sith Underlord was bestowed upon those Sith who were not quite effective enough to merit the title of Sith Lord, but were too old and irritating to keep at the rank of Sith Apprentice. Sith Underlords were often charged with the less important Sith work, such as periodically applying a fresh coat of dust and cobwebs to Sith Temples, turning kittens to the Dark Side, and sharpening Sith lightsabers when they get dull.
