One day, a new monster appeared in the sewers, infecting all the waters and causing the disappearance of many Redanian noblewomen. As the infections were killing his soldiers, King Radovid V sent a research unit, led by captain Vern Pallack and by the field medic Shani, into the sewers, with the goal of getting a sample from the monster's saliva and creating a vaccine.
The expedition however, was a failure, since all the soldiers in the unit were killed off by various monsters. Shani had luckily survived thanks to their sacrifice and was found by Geralt, who consequently had a contract to kill the monster. Together, the two found the monster's lair and, after Geralt sent Shani away, he lured it out and slew the beast.
