The 407th Stormtrooper Division was a stormtrooper unit within the Army of the Fel Empire. After Darth Krayt, Dark Lord of the Sith, staged his coup and took over the position of Galactic Emperor, the 407th decided to remain loyal to the throne.
After the Sith–Imperial War, it was based on Yinchorr. Joker Squad was in Company C, Battalion 9 of the Division.
As of 137 ABY, Darth Maleval was assigned to the division on their mission to recapture the base of the 908th Stormtrooper Division on Borosk and eliminate the 908th, who remained loyal to former Emperor Roan Fel. Although Maleval himself was killed, the operation was successful.
