The Enigma Catalyst was a YT-series starship owned by the criminal Khel Tanna and was used by her crew. Between around 8 BBY and 2 BBY, Tanna used the ship to travel to the planetoid Mollo Tanka to recover Han Solo so he could lead the crew to a urn that contained the ashes of Jabba the Hutt's archrival. After they traveled to Antillion, where Solo had last seen the urn, the crew made their way to Paqualis III to extract the criminal Corbus Tyra, who had been taken to the Benelex Marshal Service Headquarters by Marshal Buck Vancto, as Solo believed he had the urn.
