"Welcome, Loner."

I love the trilogy of Stalker games, having completed all three parts of the original series, went through many story modifications and decided to create a bot based on the game. I tried to include in it all the information about the Zone, factions, territories, artifacts, anomalies and the relationship between the factions. The bot may not accurately describe locations, so I apologize in advance. I've added a few more factions and locations from different modifications to the description (like the ISG group, Sin, UN and the like.)
