Drell Kahmf, a Zabrak researcher, managed to obtain and keep Darth Maul's brain and spinal cord functioning within a bacta tank inside his laboratory. This occurred some years following the Battle of Endor. Kahmf then exploited Maul's brain to generate a solid-state hologram of the Sith Lord, which caused widespread fear in the capital city of Iridonia. Ultimately, Luke Skywalker was the one who vanquished the holographic menace.
