There are multiple POIs in Once Human, with the Forgotten Monolith being one of the key late-game areas you'll need to search to complete your seasonal exploration missions.

One of the seasonal exploration quests for the second week of Once Human requires you to place a Whisper with a message at the Forgotten Monolith. This may seem like a simple task, but powerful enemies and a not-so-straightforward way to place the Whisper make completing this challenge quite the challenge.

Here's what you need to know about the location of the Forgotten Monolith in Once Human.

To find the Forgotten Monolith in Once Human, you will need to head to the Red Sands area, located on the northwestern side, at approximately the coordinates: 1933, -1486. Once you find the location, you will notice that the name of the location is actually Forsaken Monolith. If you found this confusing before, you can complete your challenge here.
