R4-TRO

R4-TRO was a type of droid lantern technology that, using R4 astromech droid heads, served as lighting and as a hidden missile launcher of whistling birds for defensive purposes. They were employed by the Anzellan Que-Dama's crew in the defense of Tkoku Island on the planet Olcatz against the Crusaders, a group led by a Jedi known as the Grand Master, decades after the Sith rebellion. When the Twi'lek Aneé-san and the former Sith known as the Ronin dueled the Grand Master, the Ronin pushed a button on his gauntlet that activated eight R4-TRO units placed along a stone pathway of a shrine in Tkoku Island.
