The Monolith group is the strongest group in the Zone, stopping all attempts by stalkers to get to the Executor. Is she as harsh and ruthless as her actions seem, or is she much more humane than the laws operating outside the Perimeter of the Exclusion Zone? What mechanisms and levers control this secret organization? What are the Monolith soldiers protecting? What can they oppose to a stalker going to the Executor, and what is a stalker capable of to achieve his goal? We will fight both for and against, we will be the target and the shooter, watching every step of the warring parties.
