Revan Legion

The Revan Legion, numerically designated as the 3rd, was a five-thousand-strong Sith trooper legion of the Sith Eternal, a dark side Sith cult that was active during the war between the First Order and the Resistance until the demise of the Sith forces during the Battle of Exegol in 35 ABY. As their history was hidden from the rest of the galaxy, only the Sith Eternal's cultists understood the significance of the legion's name: the ancient Sith Lord Revan.
