In view of the increasing reports of emergencies, the OSI is compelled to respond immediately. According to preliminary data, a significant threat to the existence of nearby settlements has been identified in sector H16. There are confirmed disappearances of living organisms — from insects to citizens themselves. The uniform decline in numbers rules out a rise in predator populations, since all species are disappearing simultaneously and to the same extent. The local police do not possess sufficient technology and are unable to identify the threat or its source. You have been provided housing in the least dangerous zone, as well as a device for detecting nearby hazards. If you wish, you may contact an agent at the city library. Eliminate the threat!
