In the Genshin Impact Fontaine Archon Quest Chapter IV: Act V - Masquerade of the Guilty, players will encounter the quest segment called Meeting Is Also Parting, which involves exploring ruins south of the West Slopes of Automnequi.
The ruins house a quest-limited Domain called the Place of Secrets, which you must explore while preventing Navia from being consumed by the Primordial Sea. Follow the walkthrough below to find all Chests and make it to the exit safely.
All Chest locations in the Genshin Impact Place of Secrets Domain – Meeting Is Also Parting Fontaine Archon Quest
Follow the walkthrough below to complete the Place of Secrets Domain from start to end. There are three Chests within the Domain, and you must loot them immediately as you pass through them, as you won't be able to go back to previous areas when you've progressed too far, and you also can't re-enter the Domain after exiting.
Upon entering the Domain, follow the path forward to find a clearing with Hilichurls. Defeat the enemies to trigger the nearby door to open. Go through the door and keep following the path until you reach a dead end.
As you approach the dead end, you'll notice that there are cracks on the ground. You need to step on the cracks to trigger the floor to break, but be careful not to fall or your active character will die. Try to glide instead!
Upon dropping to the ground, defeat the two Hilichurls. You'll find an Exquisite Chest beside them. Don't forget to loot the Chest as you can't go back for it later on. Once done, glide toward the other side of the broken bridge to trigger dialogue with Navia. You can turn on the quest navigator to prevent getting lost.
After the dialogue with Navia, you must find a way around the ruin without touching the Primordial Seawater. If you fall into the water while climbing, you'll be teleported back to the starting position within the room. Don't worry as you can keep trying.
Start by gliding toward the narrow land area on the left, as the right side contains puddles that will be fatal for Navia. Then, climb on the broken ladder to reach the upper level of the ruin. Reference the arrows in the image above to help you.
Once you've climbed to the second floor, enter the window on the right and keep following the path inside the tunnel. When you reach a dead end, interact with the door to open it, revealing a large outdoor area.
Follow the path on the right to cross the bridge leading to the large building up ahead, where the arrow is pointing in the image above. However, the bridge will have unavoidable cracks in it. So in the middle of crossing, you'll inevitably fall and trigger a long cutscene with Navia.
When the cutscene ends, you'll be teleported to the entrance of the building. Interact with the door to open it, revealing a clearing with a Hilichurl. Defeat the enemy to trigger the door to open, then enter the door to proceed.
I recommend consuming a dish that reduces Stamina consumption for this segment. Upon passing through the door, turn left to find a staircase and start going up. As you go up, the floor will start cracking, so climb as quickly as possible.
When you're at the top of the staircase, climb the wooden ladder upward. You'll get stuck at a dead end when you climb the longer ladder, so jump toward the shorter one to get to the top. Once you're on top, the door will open, revealing a clearing with enemies. Defeat them and proceed forward.
Like before, you need to climb collapsing staircases to get to the top. This time, a red indicator on the ground will determine when rocks are about to fall on you. Avoid the falling rocks to prevent falling off and restarting the segment. When you get to the top of the first staircase, climb the longer wooden ladder, then jump toward the shorter one as it connects to the other half of the staircase.
Climb the second staircase while avoiding the falling rocks. At the top of the staircase, don't forget to loot the Exquisite Chest, as you can't go back for it later on. Once done, interact with the door to open it, revealing a clearing with Hilichurls.
After defeating the Hilichurls, you'll unlock the mechanism inside the room. Interact with it to trigger a small cutscene. Once done, step onto the center of the room and wait for it to lift you upward like an elevator.
After the elevator lifts you up, approach the Hydro Portal close to the edge of the clearing. Enter it and wait to be propelled to the entrance of another building.
When you get dropped off at the entrance, you'll find the door already open. From here, simply enter the building and keep going forward until you reach the clearing. Dialogue with the group will automatically trigger.
After the dialogue, the Domain challenge will complete, and a Precious Chest and exit will spawn in front of you. Make sure to loot the Precious Chest before exiting, as you won't be able to re-enter the Domain after. After exiting, you can proceed with completing the rest of Fontaine's Archon Quest.
