They thought that the sickness would go away, but as time went on the rash virus spread. More people died, trade routes between countries were closed, cities became isolated, and many people deserted their homes in search of a safe area. It has now been ninety years since the rash virus outbreak and humanity has started putting itself back together.

The main surviving groups include Icelanders, Norwegians, Danes, Swedes, and Finns. Some have developed technology, others have survival skills, and even magic to battle the harsh environment. An expedition in Sweden has hired five kids from various nationalities and backgrounds to fight monsters, diseases, and sometimes both as they uncover lost history.
