Imperial Sentinal

Imperial Senate Sentinels are a special Royal Guard unit that guard the Jedi Temple on Coruscant. It is unknown if they are humans; and are known to have a cyborg voice. They have a mixture of a Royal Guards and Senate Guards helmet. They also wear grey robes and armor. They are said to have been guarding the Temple from anyone who plunders the secrets of the Jedi Order, but their real job is to wait for Jedi to return, who their ordered to attack and kill.
