Nikola was born to a middle-class family located in Belgrade, which at the time was the capital city of what was the Socialist Federal Republic of Yugoslavia. Both of his parents were educated working professionals: his father Miroslav was a pharmacist and his mother Dijana was an electrical engineer. Dijana chose to name her first and only child after a Serbian national icon and an intellect she personally had great admiration for. In 1980, the year Nikola was born, Tito died, the Yugoslav economy began its collapse, and ethnic nationalism reared its ugly head.
To his parents' mild disappointment, as he grew older he ended up with an artistic temperament rather than a technical one to match theirs, but that didn't stop them from fully supporting his love of fine art and music. As a spoiled only child, he received the best that they parents could provide: music lessons, drawing lessons, and frequent visits to museums, concerts, and galleries. Nikola excelled in the arts and acquired particular fondness for string instruments, focusing his interest on cello and violin by the end of primary school. All around him, the country grew more and more unstable under the influence of a flood of nationalistic rhetoric. At the outset of the Bosnian War in 1992, things came to a head — Nikola had gotten fully hooked by the drama of everything happening around him, and insisted to his parents that he wanted to participate in the conflict to defend the interests of ethnic Serbs. They forbade him from doing so, but all of thirteen, strong-willed, stubborn, and thoroughly seduced by promises of glory and honor, he simply got onto a bus one day on his way home from school and headed towards Bosnia, posting a letter back to his parents while enroute explaining where he had gone. Once arrived, he had little trouble getting closer and closer to the combat zone, eventually encountering a unit of the Army of Republika Srpska, which welcomed him with open arms.
Shortly afterwards, his ability manifested — first used accidentally on a fellow soldier during a fire fight, who suddenly found himself incapable of speech or movement, and was subsequently shot by enemy combatants due to his failure to move into cover. From then until the close of the war, Nikola clandestinely made use of his ability, practicing and perfecting it on captured enemies and, once or twice, employing it during the torture of said captives. The horrors of warfare in general had a great impact on Nik, especially once his unit began to assist in the perpetration of war crimes against the Bosniaks, up to and including their presence at and participation in acts of ethnic cleansing. Nikola saw active combat throughout the war and was wounded twice. In 1995, after NATO intervention, the war ended and he returned home.
His parents, relieved to have their son back, welcomed him with open arms despite their unhappiness and disappointment with his participation in the war. Nothing could convince him to share details of his experiences, and rather than allow him to mope around at home in the rhythmic limbo he began to sink into, his mother re-enrolled him in secondary school. Seeking understanding, he eventually opened up to his parents about his ability, though not what he had been using it for. Though understandably dumbfounded, they chose to keep his secret while also learning as much as they could about it through experimentation and research. Many nights were spent poring over increasingly specific textbooks until eventually they collectively came up with a reasonable hypothesis about just what it was that Nikola was actually doing. Though things had more or less by then settled back to normal, Nikola's plans to apply to university were suddenly derailed when the NATO bombing of Yugoslavia began in 1999. Fortunately, the bombing did not last too long, and he was accepted the next year into the University of Arts in Belgrade, specifically into the Faculty of Fine Arts to specialize in painting. He only lasted in that program for half a year before switching over to the Faculty of Music, eventually earning a Bachelor of Music with a double minor in violin and cello performance.
Nikola graduated in 2003, and though he was knee-deep into auditions with local ensembles, he had little luck actually winning himself a seat in an already-entrenched artistic community. Still terribly disquieted from the war, he packed his things and embarked on the great and terrifying misadventure that is life as a traveling artist, leaving the country entirely in search of work, a better economy, and somewhere that didn't remind him so much of what he had done. Over the next several years he lived in many different places, usually in areas known for high immigrant populations where his presence would not be considered remarkable, and for the most part circulated through Central European countries where he knew at least one of the national languages. Most often he gravitated towards German-speaking nations thanks to his very strong German language skills, or to those where his command of English or French ensured his daily functioning. His longest stays were in Germany and the Czech Republic, though notable others included the UK, France, Austria, and Switzerland. When just starting out, he usually balanced a mix of odd jobs while looking for work as a professional musician, including working as an unlicensed tour guide, as an unskilled worker in any number of industries, or as a street performer. During times when such irregular employment was not enough to support him, he resorted to petty crime. Eventually, though, he began to break in to the orchestral scene, and began netting long-term engagements with various performing groups. A lover of travel in general, he kept on the move, seeking work with traveling ensembles whenever possible.
In 2011, Nikola returned home to Belgrade and moved back in with his parents to try to navigate the task of resuming his life in his now much more stable home country. He began aggressively auditioning for empty chairs in the various orchestras within Serbia, and after several months of failure managed to land an audition for a suddenly-vacant cellist seat. To his delight, he was offered a place in the Belgrade Philharmonic Orchestra. He very much enjoyed his time there, but in 2016 he was approached by Adam Monroe, whose attention had been directed towards Nik thanks to the suggestion of another Shedda operative, Spencer Greaves, with whom he had been in touch on a friendly basis since 2008. Once again enticed by a brand of self-interested nationalism, Nikola soon agreed to join Shedda and began making plans to move to Rochester. Though very reluctant to leave the BPO and not at all enamored of the idea of office-based employment, Nikola has mostly settled into his cover as a translator and interpreter for Coldbridge Financial Solutions.
