The Eye of Graeae, the monocle-shaped gadget you carry across Snezhnaya, needs all three of its scattered fragments before its story can conclude. Each fragment sits at the end of a separate world quest chain, and collecting the full set is the only thing that opens the final questline, Her Palace Collapses Into the Blizzard.
Quick answer: Complete the In the Dwelling of Life, Hesperides of Love and Hate, and On One Side a Palace, On the Other a Tomb quest chains. Once all three fragments are in hand, the An Ark That Used to Be a Soul world quest begins, which starts Her Palace Collapses Into the Blizzard.

The three fragments and where each quest starts
There is no strict order for the three chains, but you need all of them done before the finale unlocks. Each one hands over a single fragment when you finish it.
| Quest chain | Fragment | Where to begin |
|---|---|---|
| In the Dwelling of Life | Pebble of Serpentine Algae | Statue of the Seven in Flamefeather Valley, southwest of Morepesok |
| Hesperides of Love and Hate | Pebble of Freezing Heart | Pick up an invitation at Svetloledovka, then go to Fellfrost Peak |
| On One Side a Palace, On the Other a Tomb | Pebble of Crystalline Essence | Triggers after the previous chain; reach White Birch Snowgrave |

Work through the full chain to earn the Pebble of Freezing Heart. The finale here is a fight against Pavlina, after which Aksinya hands you the fragment.
Start In the Dwelling of Life
This is the longest of the three chains, packed with Grappling Gun and cube puzzles, a sewer keycard sequence, and boss fights against Furiosa, Zala the Immortal Firebird, and others. It also drops a gun blueprint along the way. Finishing it grants the Pebble of Serpentine Algae.
Start On One Side a Palace, On the Other a Tomb
This chain begins on its own right after you wrap up the previous questline, so there is no separate NPC to find. Go to the Central Station and locate the Eye of Graeae inside one of the train carriages to pick the thread back up.
The mission takes you into the Snowgrave area and grants access to the Pale Crown Palace. Reaching White Birch Snowgrave is the key checkpoint, and completing the chain rewards the Pebble of Crystalline Essence, the last fragment you need.
How the finale triggers and how to confirm it
Once all three pebbles are collected, the An Ark That Used to Be a Soul world quest becomes available. Starting it kicks off Her Palace Collapses Into the Blizzard. If the finale has not appeared, one of the three chains is still incomplete, since the door to the Courtyard of Carefree Light only opens when every fragment is gathered.

You know it worked when the A Thousand Affections Caught in a Sigh achievement pops after the final battle. Even though the story resolves Goggles’ arc, you keep the gadget’s exploration powers, so you will not lose the ability to use Prime Ice Constructs, drive the train, or resist the sheer cold in Snezhnaya.
