Imperial Senate Sentinel

The Imperial Sentinels were a subdivision of the Emperor's Royal Guard and served Emperor Palpatine.

Overview
The Sentinels dressed similarly to the Royal Guards, but their armour and robes were gray rather than red, and their helmets resembled those of late Clone Wars-era Senate Guards. They wielded powerful force pikes that could effectively block a Jedi's lightsaber, which aided them greatly in their work.

History
The sentinels were handpicked by Palpatine to guard the Jedi Temple on Coruscant. Once there, they watched over the ruins and protected them from looters and those who sought to plunder the secrets of the Jedi Order. Their true purpose was, however, to wait for any returning Jedi, and those that came would be attacked and killed.

Galen Marek came to the Jedi Temple to further his training, whereupon he was attacked by a number of Imperial Sentinels. Despite putting up a valiant fight, they were killed in the struggle.
