Asia Massari was born in a Swiss bomb bunker, which had been occupied by a good number of civilians in the early days of the Rash infection, a few days before it reached Italy. In this bunker, the government of Switzerland had accumulated sufficient food reserves for many years, as well as considerable stocks of weapons, ammunition and medicine. Over time, the survivors of the bunker also managed to develop small-scale crops and renewable food sources, and planned what they intended to be a peaceful society, safe behind the heavy defenses of the bunker.
Unfortunately, after a few generations quarrels and disagreements began to arise among the descendants of the original survivors. The reasons for these disagreements were due to the ever-increasing number of bunker dwellers, which had increased the demand for food and placed the inhabitants at a crossroads.

The girl soon learned the basic rules of survival in a hostile environment full of dangerous creatures: first she learned to recognize, hunt, kill and cook non-infected animals; then she learned how to hide from Beasts, Trolls and Giants, then to avoid them and later to fight and kill them. However, Asia has never Encountered other uninfected humans, which has led her to convince herself that she is the last human being on Earth.
To this day Asia travels through the Silent World, constantly searching for supplies and shelters to hide in during the summer (Asia tends not to travel during these times, as summer is the time when Trolls, Beasts and Giants are most active) being careful not to become prey for the monstrous abominations that populate the continent and the daily challenge of the Rash...
