Read the Journal at Grayclaw Forest

Proceed to the Eastern Guard Post at Grayclaw Forest, then talk to the Observation Post Officer. Afterward, go read the Journal found on top of the crate near the officer. The journal entry mentions a place called the Lycans' Hall, so that's where you'll be heading to next.

Follow Harden's Trail

Follow the trail left by Harden, as these will lead you to the location of the Lycans' Hall. You'll be traveling through the Grayclaw Forest and following clues such as bloodstains and scratch marks that are seemingly left by a werewolf.

At the end of the trail, is a door leading to the Lycans' Hall. Enter it and then speak to Clay who is performing a magic spell on the altar below.

Solve the Two Moon Puzzles

1. First Moon Puzzle Solution
2. Second Moon Puzzle Solution

The first moon puzzle is simple and only requires you to touch the Yellow Half-Moon pillar, followed by the Blue Half-Moon pillar. The second moon puzzle is a bit complicated, as you will have to combine Blue and Yellow Moons according to their shapes.

Moon Puzzle Solution: At the Lycans' Hall Quest

Combine Blue and Yellow moons together. Touch the Full Moonstone to get a half-moon piece. All pillars will then briefly show their corresponding moon piece. Look for the one that will fit in correctly with the moon piece that you have. Keep combining them until Clay tells you to stop.

Obtain Ingredients at Purelight Hill

Talk to Clay at Canina Village and he will send you to Purelight Hill to collect x7 Contaminated Mitran's Spirit by defeating Mitrans. You will also need to collect x1 Dawn Weed, which is a harvestable bush in the area.

After collecting all ingredients, hand it over to Clay who is at his office in Purelight Tower.

Investigate the Traces of the Resistance

Speak to Officer Auguist at the Ruins of Turayne. Afterward, interact with the black mists in the area. There are a total of 7 that you will have to investigate.

After investigating all traces, a Black Energy portal will appear. Interact with that next and you'll be transported to a dark realm.

Light Up the Dark Path

Approach each light source and wait for Helpie to rotate the beam to light up the dark path ahead. Avoid going in the dark or else you will be stunned and will be sent back to your previous position. You will also have to defeat enemies along the way, but make sure to stay within the light when doing so!

At the end of the path, you will be transported back to the real world. Speak to Clay and return to Purelight Tower.

Find a Book About Sylaveth

Head to the Library on the first floor of Purelight Tower and speak to Clay again. Search the books around the library until you come across a book that mentions Sylaveth.

Defeat the Arkeum Legion

The Arkeum Legion will then attack the tower. Defeat all of them and make your way to the top of the tower, where you will see more Arkeum Legion attempting to bind Gigantrite with some sort of magic.

After defeating all the Arkeum Legion, speak to Clay and you will be transported to the Shattered Temple.

Choose an Ally to Accompany You to Temple 2

Follow Sophia to the assembly area. Here, you'll have to choose from Sophia, Rutaine, or Robert, to accompany you to Temple 2.

Go With Sophia, Rutaine, or Robert?

Deactivate the Pillar of Immortality

Defeat the Gallu soldiers that are seemingly linked to the Pillar of Immortality, since you cannot deactivate it if they're still alive. Once done, deactivate the pillar.

Inject the Barrier with Mana

Examine the stone monument - this will turn your ally into stone and summon two Gallu soldiers! Defeat the soldiers and then interact with the Rift of the Barrier at the doorway to inject it with mana.

Avoid Berge's Eyes

Move to Temple 1 while avoiding Berge's Eyes. You will have to hide behind walls and move between cover to avoid it.

How to Avoid Berge’s Eyes

Step-by-Step Guide

#	How to Avoid Berge's Eyes
1	Move to the first wall by the entrance of the ruins.
2	Turn around and move behind the stone archway.
3	Stay here and wait for the eye icon to shut close.
4	Turn around again and run towards the half-wall for cover.
5	Use the piton on the floating pillar nearby.
6	Glide towards the other side. Berge's eyes will no longer affect you here.

Follow Clay to Berge's Portal

Go to the Light Sanctum Ruins and follow Clay to the portal leading up to Berge. You will have to deactivate another Pillar of Immortality before entering the portal.

Defeat Berge

The final battle in the Nightmare Deja Vu quest is against Berge. The only mechanic here is once he becomes invincible, you will have to collect all the blue fragments on the ground to remove his invulnerability state. Other than that, it's a pretty straightforward boss fight.
