How to get the If Not Us, Then Who? Hidden Achievement in Genshin Impact

They were merely pawns in the Tsaritsa's grander scheme.

If Not Us, Then Who? is a Genshin Impact Wonders of the World Achievement that can be obtained by collecting the letters of The Fatui in The Chasm. It's tied to a Hidden Exploration Objective that involves searching for four of the Fatui Action Logs, which also give you more context on the fate of the people who were trapped in The Chasm's Underground Mines.

Before starting, make sure you have access to The Chasm: Underground Mines, which unlocks after completing the World Quest called The Chasm Spelunkers.

Where to find all Fatui Action Logs in The Chasm in Genshin Impact

To get the Hidden Achievement called If Not Us, Then Who?, you need to read four Fatui Action Logs scattered around The Chasm's Underground Mines in any order. You won't get any quest items or indicators of your progress.

Fatui Action Log: Part I

Head to the southern Teleport Waypoint in The Chasm: Main Mining Area. You'll immediately spot a cave that will lead you further southwest, where the arrow is pointing in the image above. Follow the path until you spot a huge clearing.

You'll spot the iconic tent used by the Fatui all over Teyvat. Approach it to find two crates to its left. Interact with the glowing spot on the leftmost crate to read the Fatui Action Log: Part I.

Fatui Action Log: Part II

Head to the Teleport Waypoint northeast of the Stony Halls. You'll find a giant crater up ahead. Your goal is to glide toward the spot the arrow is pointing to in the image above, which is essentially the southwest part of the map (do not jump into the crater).

Once you're on the other side, follow the path toward the area guarded by a Pyro Abyss Mage. You may have to defeat it as you can't interact with objects when targeted by an enemy. You'll also find a ton of Oozing Concretions inside.

Follow the path forward until the shallow water connected to the waterfall is visible. You'll see that there's a hidden path under the broken pathway. Go underneath and follow the path until you reach a dead end.

The last log is the easiest to find. Head to the Teleport Waypoint in The Glowing Narrows and keep going straight, toward the area marked on the map above. You'll find an abandoned Fatui camp with a glowing spot. Interact with it to read the Fatui Action Log: Part IV.
