Immernachtreich Apokalypse is a long story quest in Genshin Impact.
Your objective is to enter Fischl’s mirage and figure out what’s going on.
Here’s a walkthrough and guide of Immernachtreich Apokalypse in Genshin Impact.
To begin the quest, change the time to anywhere between 6 am – 12 midnight.
Inside the first mirage, you will be taught on how the Gaze of the Deep works.
Use the Gaze of the Deep
At the start, use the device to fix the bridge. Climb up the bridge.
In the next room, you will see two parts that need fixing.
Fix the staircase going up first.
Then, climb up the staircase and head to the lift. Use the lift and go down.
Now, use the Gaze of the Deep again and fix the bridge now.
As the staircase is gone, take the lift up and cross the bridge.

You will need to fix the bridge outside using 2 Gaze of the Deep devices.
Cross the bridge and enter the castle.
Find the source of the voice
Now, find the source of the voice.
You will learn that the voice is from a statue named Leon.
Use the Gaze of the Deep devices to repair the path in front of Leon to allow him to get out.
Talk to Leon after he is safe.
Repair the path to the tower
He will have told you the password. Go to the barrier and use password.
Use the device to repair the path to the tower. Start climbing up.
Close the Hymn Book
At the top of the tower, close the book to leave this area.
You will end up in Fischl’s room in another mirage. Leave the room to exit the mirage.
You are done with the first volume of Hymn of the Holy Land.
Look for the second volume of Hymn of the Holy Land
You will now need to look for the second volume of the Hymn. Go to the bottom of the hill in the middle. You will see an elevator.
Use it go all the way up the hill.
Make your way up until you reach the guards.

Enter the library
Head to the library which is blocked by the barrier. Use the new password.

You will be teleported to a hallway. Here, you just need to wait for the conversation to finish.
Walking all the way will lead you to a dead end anyway.
Look for the third volume of the Hymn of the Holy Land
Now, head north to look for the third volume of the Hymn.
From where you are, climb up the tower. From the top, jump and glide to the northern hill.
Make your way into the castle and you’ll see the same guards.

Repair the bridge
The Gaze of the Deep this time has a different function yet again. How it works is that the cube has to be in the middle of the focus.
Once it’s done, the bridge will appear.
Look for the missing pieces of the toy castle
Here, you need to find two missing pieces of the castle.
I chose the left route first. Take out the monsters.
You will now reach a Gaze device. Use it to proceed.
If you continue to follow the path, you will reach a ladder. Climb up and you’ll see a Gaze of the Deep device but it doesn’t work because there’s no object.
Jump down and glide to the Gaze device located further below (image below).
Use this device.
Then, use the elevator to go up.
Now, go back to the Gaze of the Deep device earlier. You can now use it to create a ladder.
Make your way up.
Follow the path and you’ll reach a missing piece of the toy castle.
To go back, use the wind current.
Now, head to the right side. Defeat the monsters along the way.
Use the Gaze device to build a path.
Jump and glide to the next part.
In this area, you will see monsters all over. Clear them first.
Now, look for the only Gaze device that has a cube in front of it. Use the device to form a cube.
Then, head to the next device which faces the newly formed cube.
You will see that there’s a small cube beside the big cube.
Focus on the small cube.
Next, head to the device which faces the small cube of the newest big cube. Use the device to form a ladder in front.
Use the ladder to go up.
Follow the path until you reach a noticeboard.
From the noticeboard, jump all the way down.
At the bottom, you will see two Gaze of the Deep devices, one on the left and the other on the right.
Use the one on the left first.
Then, use the one on the right.
Now, use the wind current to glide to the newly formed floating cubes.
From the big cube, you should see wind currents on the side. Use the wind to glide.
Make your way to the other side with the low staircase.
Follow the path and you’ll reach the last missing piece of the toy castle.

Talk to Leon once he’s rescued.
Enter the upper floor
With the third password, head up the stairs and use it on the barrier.
Make your way to the upper floor of the castle.
Close the Hymn of the Holy Land.
Go to the high terrace
