Genshin Impact ‘Through the Looking Glass’ hidden mirror locations and walkthrough

“Through the Looking Glass” is a Genshin Impact world quest with with a twist: It doesn’t show up in your journal unless you’ve found every looking glass — a purple glowing mirror. And whenever you find such a looking glass, you also need to complete a small puzzle that involves a sunflower painting and a fish. If that sounds like a difficult task, you’re absolutely correct.

In this Genshin Impact guide, we’ll walk you through “Through the Looking Glass,” and show you where to find all hidden mirror locations and complete the corresponding looking glass puzzles.

How to start ‘Through the Looking Glass’

To unlock “Through the Looking Glass,” you need to do the following:

• Complete the world quest series “In the Wake of Narcissus”
• Complete the ‘Book of Esoteric Revelations’ world quest

Beware that “Through the Looking Glass” is a hidden world quest, so it doesn’t appear in your Journal even if you meet the requirements. Follow the steps below to complete the quest.

All ‘Through the Looking Glass’ mirror locations in Genshin Impact

There are six hidden mirror locations in “Through the Looking Glass,” and all of them are found in Fontaine’s Morte region. Here’s an overview of all mirror locations:

Whenever you find a looking glass, interact with it to enter the other side. Here, you will find yourself in a room with a painting of sunflowers and a small glowing fish. In each looking glass location, there’s something you must do to make the fish swim through the painting. Once that is done, the looking glass location is ‘completed’.

The overview below will show you all “Through the Looking Glass” hidden mirror locations in more detail, and explain each painting puzzle.

After going through the looking glass, light up the torches below the flower painting, using Pyro attacks, and turn off the other four torches using Hydro attacks. This will make the fish swim through the painting.

Swim to the sunken Tower of Ipsissimus and enter the lower floor, then swim to the middle of the room and choose “enter.” This will take you further inside the building, where you’ll find the mirror location in the next room, hidden from view behind a wall.

The path to the treasure chest is obstructed by invisible walls, but if you swim low and stick to the right, you’ll be able to reach it. Open the chest to release the fish.

Once you’ve completed the six looking glass puzzles, you’ll be transported to the world inside the “Book of Esoteric Revelations,” where a final conversation with Canotila will complete the “Through the Looking Glass” hidden quest.
