The use of the term Jedi Sentinel, first introduced in Star Wars: Knights of the Old Republic as one of the Jedi starting classes, was solely created for the game, and has only recently appeared in the pen and paper Saga Edition of the Star Wars Roleplaying Game as a Talent Tree for the Jedi class. This class is mostly signified by its use of yellow lightsaber blades. In Star Wars: Knights of the Old Republic II: The Sith Lords, the prestige class that corresponds to Jedi Sentinel is Jedi Watchman. The dark side counterpart is Sith Assassin; it should be noted that Jedi Watchman also appears in other canon works, such as the Tales of the Jedi comics and others. The class presumably became canon in the Star Wars: Knights of the Old Republic comic series along with Jedi Guardian and Consular.
