The Sith tattoo indicating the status of a Dark Lord of the Sith was a symbol displayed on the forehead. This specific mark was borne by various Dark Lords, for example, Naga Sadow together with Exar Kun. In the year 3997 BBY, the spirit of a Sith Lord, specifically Marka Ragnos, bestowed upon Kun the Dark Lord's mark and upon Ulic Qel-Droma that belonging to a Shadow Hand.
