"Sith Infiltrator" was a term used to describe various designs of starships used by Sith Masters and apprentices during their long centuries of secret actions against the Jedi Order. Darth Sidious and two of his apprentices used highly customized Star Couriers to serve as their Sith Infiltrators. The Scimitar, used by Darth Maul was, in its time, perhaps the most dangerous Infiltrator ever created.
