QS - 2D QS - 2D was a heavily - modified protocol droid - turned - entrepreneur . Its left hand had been turned into a weapon mount for a blaster pistol , it had been fitted with deep black armor plating , and it had been reprogrammed to serve as an administrative droid . It had been altered to serve basically as a combination of personal assistant and body guard , and was given a heuristic processor which gave it a capacity for a great deal of independence . History . QS - 2D was originally owned by two Twi ' leks who tried to scout the moon of Uffel around 90 BBY . When the Twi ' leks were killed in the landing , QS - 2D decided that its independence was permanent . The droid , along with its companions R4 - S2 and R4 - J9 , began a self - repair routine extracting components from the beached ship , and while doing so , QS - 2D reprogrammed the droids to became their master . They then surveyed the planet and , satisfied with the results , decided to started up a small mining operation . QS - 2D established a financial relationship with Riboga the Hutt in order to do this . In exchange of a part of its profits , Riboga provided QS - 2D with droids , including power droid , miner droids , more astromech droids , and at least one protocol droid and one medical droid , 4 - KT , who would become one of QS - 2D ' s droid development expert . All of the droids of Uffel were programmed to acknowledge QS - 2D as their master , but QS - 2D worked under its former master ' s name , who was officially still alive but never seen , so as not to draw attention to itself . Although QS - 2D obtain good profits with the mines , it understood the mines would eventually dry out , so it decided to diversify its business venture : It re - invested in droid factories and developed different droid designs , including a variant of the MSE - series known as MSF - series : message - carrier and mechanic repair expert , it could hover with little repulsorlifts and work in cramped conditions . The MSF was a commercial success and it became the main credit influx after the mines stopped working . QS - 2D retained the MSF prototype , silver MSF - F2 , and used him to openly and relentlessly follow any visiting organic . In a few years , QS - 2D was rich and owned more than one hundred droids . QS - 2D built a city for his droids , X2 - 4 , around the droid factory . The city had a spaceport operated by a single droid , but it lacked commodities for air - breathing organics because QS - 2D did not trust them : Clients wanting to visit needed breath masks and pressure suits . As the droids knew no greed , QS - 2D assigned any income to maintain , enlarge or improve the city it ruled . QS - 2D , worried about security even in a pressurized environment , designed a local model of battle droid to protect the city , including its security chief HG - 211 . QS - 2D also built engineering droid G - 8Y5 to maintain and modify existing droids and to develop new designs . G - 8Y5 collaborated in the security effort by designing and constructing droid - based space defense weapon platforms . When the droid made enough of a fortune , it bought out Riboga ' s part — just in time , as Riboga left the Cularin system soon afterward . The droid moon produced some of the highest - quality specialty droids of the Old Republic . QS - 2D was demanding , wanting perfection in everything , but practical enough to realize it could not always achieve it . It was creative and had an ability for administration which it had not been programmed for . However , QS - 2D also grew to distrust living beings , believing they would take away all he had created . The droid could become impatient with the living beings it dealt with if it did not feel they were being direct in their dealings with it . In 32 BBY , QS - 2D owned more than one thousand droids and counting , all of them happy to work for a fellow droid instead of an organic . However , to keep a low profile , QS - 2D still maintained that he was working for an unseen Twi ' lek master . Its droids were used all around the system , except by crime lord Nirama , who mistrusted droids that could include espionage programming .
