Horizon Forbidden WestΒ Vezrehβs Chamber is a critical location youβll have to investigate at the end of the Shadow In The West side-quest in the game published by Sony Interactive Entertainment. Horizon 2 Forbidden WestΒ Vezrehβs Chamber investigation requires you to find several clues or Datapoints you have to scan, but it also comes with a hidden chamber you may need help finding.
Therefore, if you want to know how to investigate Vezrehβs Chamber in HZFW, throughout the following guide, weβll approach this objective and how to complete it.
Where To Find Vezrehβs Chamber
Vezrehβs Chamber is in Shadowβs Reach, which acts as a small Stronghold youβll need to clear while playing Shadow In The West. My map below shows that itβs on the western side of the second region.

Without spoiling the story or the quest, the actual Chamber is reached after you meet Vezreh. Once you do that, the game automatically closes the area where you meet him, and after a cutscene, Aloy wakes up in his Chamber. Now, your new objective is to investigate Vezrehβs Chamber.
How To Complete Vezrehβs Chamber Investigation
Vezrehβs Chamber investigation involves a series of Datapoints that Aloy can scan with her Focus. Specifically, there are 3 of them, and you can scan them in any order you want. The moment you reach Vezrehβs Chamber, instead of heading outside, turn around and follow the tunnel.
Head left around the corner, keep moving forward, and turn left again to get to a small room. Here, first, youβll have to scan the Datapoint thatβs close to the bed (pictured below).

Now, youβll want to use the Pullcaster to remove the grate on the ventilation shaft (also pictured above). Crouch and head inside the ventilation tunnel, then remove the grate on the other side, and youβll reach a hidden room. Here, make sure you scan the second Data Point (marked below). You should see it on what seems to be a desk.

Now from your current location, retrace your steps back to the previous room (via the ventilation shaft), then back to the area where you started. Before heading outside, there is one last Datapoint you have to scan. As you can see, itβs on the right side while facing the exit.

Scan it, and then youβll activate a hologram. Once the recording ends, youβll have to talk to Yef, and the Forbidden West Shadow In The West quest ends.
