SE4
a series of servant droids manufactured by Industrial Automaton, the 1.6-meter-tall SE4 was the first major series of droids produced by Industrial Automaton, and helped them grow into the huge corporation they are today. One of the oldest known droid lines, the SE4 resembled the humanoid 3PO protocol droid in shape, and can be equipped with various personality modules. They are used throughout the galaxy in cantinas, messhalls, and tapcafes.
