Rescue Pilgrim

After talking with Skygazer, Fang contacts you and sends you to help Pilgrim, who got captured in the Old Village. He gives you the transition there.
This quest is completely unmarked and doesn't have any canonical name.
== Walkthrough ==
Travel to the Old Village through the new transition. You find yourself trapped in a tunnel together with Pilgrim and another stalker, and immediately hear the radio transmission by Lieutenant Whirlybirdson reporting to his Captain that one more stalker got caught into the trap, and they should dispose of the previous "batch" of stalkers in the meantime.
Talk to Pilgrim. Turns out that the Old Village is a military outpost, and they set up a teleport trap here. These seem to be special forces who periodically exterminate anything that moves in selected parts of the Zone.
Try entering the teleport and get thrown back. After that, a stalker named Kolmogor enters the tunnel and deactivates the teleport. Speak to him. He's asking you to save that group of stalkers that was supposed to be executed, starting Brother for a brother.
