Strelok and his allies, Ghost, Fang, and Doc, were a group of Stalkers who had a particular interest in what exactly lay at the center of The Zone. At some point a few weeks before the start of the game, they managed to slip past the Brain Scorcher and all the way to the Nuclear Power Plant, finding the Monolith, an electronically locked vault door beneath the Monolith chamber (which leads to C-Consciousness), and documents hinting at the fact that the giant glowing Monolith was in fact a deliberate trap for anyone attempting to discover the secrets of the Zone. Unfortunately, they were forced to retreat, and their next attempt to penetrate into the heart of the Zone met with disaster. They had managed to obtain an electronic lockpick that would open the vault door, but this time the Monolith was ready for them and they were forced to retreat again, and their escape was further complicated by a blowout. Strelok was caught in the blowout and rendered unconscious with a severe case of amnesia. This made for a perfect subject for the conditioning process for a human agent of the C-Consciousness entity. Ghost and Fang escaped, but Fang was seriously wounded and died before the pair made it out of Pripyat, with Ghost moving on to find "safer" work in the outer regions of the Zone.
