Karel Nivek, widely known as "Big Dick" Karel, was one of the prominent and key personas in the Nivek family. He was the big bad bully in school and he never stopped being that. With his dominant personality and big force, he took control of the drug business controlled by the Niveks when his father Kamil died. During his reign, the business was working better than ever. He knew when to push and be intimidating or when the backup and leave people a moment to think. His name and seed spread quickly throughout the whole city and so people knew not to fuck around on his part of the city.
As the business grew, problems showed up and got dealt with and so did multiple people that tried taking him down. During some business meeting, he met with a Russian dealer that proposed to him a new job in Moscow. At first, he laughed it off, but hearing of what they have been doing there and new and improved lifestyle he could have, he decided to take him on his offer and disappeared to Russia where he would take care of the distribution in the Moscow region.
When the infection hit, Karel and his Russian friend built a place for people to stay, where they also started dealing with drugs again. As time passed they cut a deal with a settlement from Sevastopol, Ukraine where they would transport all sort of things like slaves, women, kids in return for chemical components. Karel and his friend have been discussing extending their reach and looking out for other settlements so, after a trip to Sevastopol, Karel took a few men and went towards Takistan and then Chernarus.
