William is a medical student in his last year of residency. He decided to travel to Europe to finish his last year, and had heard of a recent new discovery in infectious diseases. While studying in Germany, William was made aware of the spreading infection that ultimately will change the world. He traveled from country to country with a team of doctors and medical professionals to learn as much as he could about this new disease. Close to a breakthrough, his team began traveling towards Northern Europe to meet with a large team of doctors who were famous for infections and similar outbreaks. While traveling in Poland, William's team was ambushed by a group of slightly infected townspeople who recognized the team's medical equipment, hoping for a cure. William was able to escape, but the other members were not as lucky. Fortunately, he was only slightly injured, and the attackers did not care for the research or documents that would ultimately prove most important to his research. William traveled solo as the months passed, eventually landing in Chernarus, where he has been told is the epicenter of the plague. Here, he is hoping to find some sort of group that has access to equipment he needs to further research this infectious plague.
