Dominik was born in Krakow, Poland. The son of a Polish woman by the name of Selina Romanowicz. This was unbeknownst to his father, Felix Czolgosz who had been briefly seeing the woman months earlier. At the time the two both lived on the island nation of Taviana. The relationship never lasted due to Selina's feelings on Felix's work. He was a descendant of the Czolgosz Otriad, a group of resistance fighters that had worked against the Nazi's on the island during WWII. Before the Otriad could be caught an exterminated, Russian forces had landed on the island and started to take back the island. A few of these soldiers happened to be Chernarussians, transferred and sent miles from home as fodder for the frontal assault on the island. Selina's father was one of those soldiers, he stayed instead of going home after the war was finished. Felix's family however had deep seated resentment for what had happened during the war, and the Otriad continued as a secret society. They indiscreetly hunted down former Nazi supporters in their homeland. They took the weapons they had hidden and acquired during the war and supplied to various groups over the years to causes they felt sympathy for. Selina did not want this kind of life for her child, so when she had the chance she broke off her relationship with Felix and returned to Poland.
After few years , Selina could not help but feel guilty for keeping Felix from his son. She traveled back to Taviana so the boy could meet his father, but Felix had moved on he had a wife and daughter now. She had to tell him the truth though, and it made him bitter. She had kept his only son from him, but his family understood. His wife had made him promise to keep his business away from their daughter, Violeta. It was settled that Selina would live close by so Dominik could know the rest of his family, though there was tension and it was awkward between the children's parents.
Felix tried to teach his son as much as he could with Selina's approval, life lessons, surviving in the wilderness, hunting, shooting, but nothing to do with the Otriad. The one thing Selina and Felix could both agree on would be their love for music, and that is something they passed onto their son. Dominik and Violeta soon grew to be very close, making sure he would be there for his little sister whenever she needed. When Dominik was old enough, they decided to send him abroad for a better education, where he would spend many years in the United States. He continued his passion for music and discovering an interest in wildlife protection. During this time, Selina's parents had traveled to Chernarus to pay their respects to former comrade and friend. It would just happen to be at the same time, as the beginning of the Chedaki uprising, where they would be killed.
Finishing his studies Dominik returned home to a devastated mother. He wished to keep her company whilst she mourned, and in need of work during his stay he turned to his father. The Czolgosz' had turned their attention to shipping as a 'legitimate corporation' whilst managing to smuggle a few illicit goods on the side. From there, Dominik would meet the darker side of his father's people, and his. The work was simple, at least at first. Taking goods back and forth from the island to Poland and Lithuania was enjoyable, and a change of pace. But one day that would all change. Dominik's father would have a special request asked by a new customer and Felix felt this was the chance to have his son prove himself. He had other business to attend to and felt the matter was simple enough. The dead-drop was set and Dominik went out during the night whilst everything was peaceful at home. This was all a ruse to get back at his family however, as armed men stormed the Czolgosz residence and kidnapped Violeta. A ransom was made and she was returned a few days later beaten and bruised after it had been payed. Dominik was furious, at his father, the company, everyone. No one could calm him down until his sister asked to see him. He went to her room, and she had the phone of one of the men who had taken her. She had stolen it whilst they were drinking. It was a fellow who lived a town over, they had met him from time to time when they had run errands. And he would be found dead a few days later laying in the fields outside of Kopech.
Following the end of the Civil War in Chernarus, Dominik left home without any notice. He had traveled to Chernarus to help with the reconstruction effort that had begun. He stayed there over the next few years to avoid the pain his family had caused him, and to find those who had known his grandparents. His search was not very successful with many people missing and homes burned after the war. After a while he became employed with the Wildlife and Ecological Institute of Chernarus to protect the native creatures and historical landmarks across the region as part of an effort to take better care of the land so dear to the Chernarussian people. He would be quite successful in this endeavor, becoming quite knowledgeable with the lay of the land, protecting the wildlife, and helping with anti-deforestation efforts. In the summer of 2017 Dominik had found himself working particularly in the South Zagoria area checking on the status of the wildlife population. When the bombing had begun he was further south unable to reach some of his fellow rangers to the north. Two weeks in he has had little contact with his co-workers or government officials and searches for some signs of stability.
