Through Time and Space Witcher 3: Wild Hunt Quest
Suggested level: 26
Group: Main Quests
Location: Novigrad
You will receive this quest from Avallac'h when you talk to him at Dandelion's tavern, which is one of the objectives of the "Final Preparations" quest. He will then introduce you to his plan to weaken Eredin.
News that Ciri and Geralt had defeated and killed Imlerith reached Avallac'h at once. I don't know how this happened, exactly, save perhaps that quickly learning of such things is the very essence of being a "Sage."
At any rate, a wild notion possessed him. What if they could now sway Ge'els, one of Eredin's most powerful allies? What if they could bring him over to their side? A key general and advisor, Ge'els was the individual Eredin relied on for reinforcements. For his plan to work, he would need a dreamer, so Triss pointed him towards Corinne Tilly in Novigrad. Thus, by the time Geralt and Ciri rode into town, everything had been arranged. Now all they needed was Ge'els...
To reach him, Avallac'h and Geralt would need to travel to the land of the Aen Elle, a voyage that would involve interdimensional travel, which in turn meant a whole lot of teleporting. Geralt vomited a little in his mouth and prepared to face the music.
Quest stages of Through Time and Space
1. Join Avallac'h. / Follow Avallac'h.
Avallac'h will be waiting for you near the house you once visited while doing the "Novigrad Dreaming" quest.
Follow Avallac'h to the basement of the house. Using the Aard sign, destroy one of the walls and get access to the first portal.
2. Find the next passage. / Wait until the passage opens. / Kill the monsters. / Travel to the next world.
After using the first portal, you will both move to the Ddiddiwedht Desert. Follow Avallac'h until you reach the next portal. When you get there the portal will be inactive and you will have to wait for the portal to open. Unfortunately, after a while you will be attacked by local monsters - sandstorms (25). Fight them and as soon as the portal appears, enter it.
When you get to the next world, it will turn out that you are here alone.
An unpleasant surprise was in store for Geralt after he departed the Ddiddiwedht Desert: Avallac'h was no longer with him. The Sage had warned him that something of the sort might happen, but Geralt had quietly hoped this would not be the case. His hopes had been misplaced, and now the witcher would have to stumble blindly and alone as he searched for the passage to the next world.
3. Find the next passage.
After walking down some stairs you will soon see the next portal.
There will be poisonous fumes all around. Golden Oriole won't protect you from them, so you'll have to run through them quickly and take breaks in the higher areas.
On your way, you'll come across a place of power - Aard. Use it, because you'll never come back here again.
You'll have to go down to the bottom of the valley and then go to the other side.
When you enter the portal, you will be moved to the underwater world.
4. Find the next passage.
Once you pass through the portal, you will land underwater. Luckily, the next portal is not far ahead of you, so just swim towards it.
5. Find the next passage.
The next world you'll find yourself in will be extremely cold. Approach the ice wall and destroy it with the Aard sign and you may leave the cave.
A blizzard raging outdoors will cause you to take damage when you're exposed, so sprint and take cover behind rocks, etc., where you can use food or potions to refill your health bar. The bonfires, stoves, etc. also enable quick regeneration, just ignite them and stand by them for a while.
Try to get to the house downhill as quickly as possible, for example by sliding down an icy slope.
Once you exit this house, you will notice the lighthouse where a fire is burning. It will be your next target.
6. Get to the lighthouse.
Follow the path down to the lighthouse, hiding in the various buildings and regenerating the life points lost when you are exposed to blizzards. Along the way you can come across several hounds of the Wild Hunt (27) that you will have to kill.
When you get near the lighthouse, enter the cave at its base.
There you will find Avallac'h warming up by the fire and you will be able to talk to him for a while before you go any further.
7. Travel to the next world. / Follow Avallac'h. / Talk to Ge'els.
You'll end up in the land where Ge'els is. Follow Avallac'h and soon you will find him and you will be able to talk to him.
He will agree to go with you and you will return to the tavern where you will show him with the help of the oneiromancer - Corinne Tilly, that Eredin killed his previous king.
After witnessing the dream, Ge'els will tell you how you can lure Eredin into a trap using the Sunstone and will agree not to help Eredin when the battle starts. Then Avallac'h will help Ge'els return to Tir ná Lia and the quest will end.
Ah, what I wouldn't give to see with my own eyes what Geralt saw in the worlds he traversed. Yet most intriguing of all seemed the world of the Aen Elle, the end point of Geralt's and Avallac'h's journey. To behold the glories of this ancient elven civilization… but alas, fate granted this privilege not to a poet but to a witcher, who returned not with paeans to the distant world's beauty, but with a general of the Wild Hunt - one Ge'els. I must be fair, however, and state that the general proved useful.
Avallac'h decided to bet all on the ace he had tucked up his sleeve. With the help of the dreamer Corinne Tilly, he proved to Ge'els that Eredin had killed Auberon, the erstwhile king of the Aen Elle and the object of Ge'els' undying devotion.
Confronted by this revelation, Ge'els could hardly return to business as usual. He struggled internally for some moments before revealing the one way Geralt and friends could hope to defeat Eredin and company. They would have to battle Eredin and the Hunt in their own world and on their own terms. The first step - to use the Sunstone to summon the Naglfar. A plan of action was devised - Geralt, Ciri, the sorceresses and Avallac'h would sail to Skellige to find the stone, while Zoltan and I would stay behind in Novigrad to keep the hearth fires burning and secure our friends' return.
