Thaniel needs your help to save his life.

Thaniel is a boy who has been trapped in the Shadowfell region of Baldur’s Gate 3 for over a century. You first learn about him through Halsin, the Druid who stays at your camp if you saved Emerald Grove from the goblins in Act One.

But after speaking with Art Cullagh at the Last Light Inn, Halsin will learn more and find a way to bring Thaniel back.

Of course, he needs your help to do so.

How to find Thaniel in Baldur’s Gate 3

The easiest way to find Thaniel is to complete the Wake Up Art Cullagh quest, which you can receive at the Last Light Inn. During this quest, you’ll learn Thaniel’s location and can continue working through the updated objectives of the Lift the Shadow Curse questline to find Thaniel.

If you continue talking to Halsin throughout Act Two when you’re in the Shadow Cursed Lands, he will mention Thaniel as his biggest failure. Halsin has no idea if Thaniel is still alive after all these years, and without more knowledge, he has no way of finding him.

How to start the Wake Up Art Cullagh quest in BG3

To start the Wake Up Art Cullage quest, you must first find him. Art Cullagh is lying ill on a bed in the side room of the inn, roughly at the coordinates X: -64 and Y: 163.

  1. After finding Art, speak to Halsin who will make his way to Last Light Inn right after your conversation.
  2. Go back to Last Light Inn and use the Battered Lute you obtain from defeating Malus Thorm in the House of Healing to wake Art Cullagh from his slumber.
  3. After waking up Art Cullagh, he will utter a few words about Thaniel’s whereabouts. But this only applies if Art is still alive.
Tip:

Halsin will be found on the bed next to Art Cullagh until he is awoken. His dialogue will not progress much if the story of Art Cullagh is not woken.

How to talk to Art Cullagh if he’s dead

If, for some reason, Art is dead, use Speak With Dead to get what you need out of him. This will still jump-start the quest with Halsin.

Speaking to Art is the key to finding Thaniel and lifting the Shadow Curse. Unfortunately, this character can die but Speak With Dead will definitely work.

How to complete the Wake Up Art Cullagh quest

Once you’ve obtained the information about Thaniel’s location, the Wake Up Art Cullagh quest will be complete, and you’ll have a new objective under the Lift the Shadow Curse questline.

Halsin will ask you to meet him by the Lakeshore—a short walk from the Last Light Inn, roughly at the coordinates X: -74 and Y: 204.

Meeting Halsin will reveal that he plans to go into the Shadowfell to rescue Thaniel, and you need to stay behind to protect his portal from waves of enemies.

You will obtain a detrimental task after progressing the storyline a bit more. Keep Halsin alive. Shadow enemies will continuously spawn after Halsin leaves and will prioritize attacks against the portal. Thankfully, the enemies have low health. You must prevent them from damaging the portal too much since this will close it and leave Halsin trapped.

Attacks like that can hit multiple targets like Magic Missile are extremely useful. But the biggest advantage you will have here is Shadowheart. Move her into an area where she is near a large group of enemies and use the Turn Undead spell. I waited until turn two because this let me hit more enemies.

You may have to reload and try again since some of it is luck. But, once the task is completed, Halsin will return with Thaniel, and any remaining enemies will die. Halsin, however, explains there is something wrong with him.

Return to camp and speak to Halsin, where you can recruit him as a companion. He’ll tell you Thaniel is missing part of himself and task you with finding an area with floral blooms.

The area should be marked on your map, but it appears to be bugged, as it did not for me. You can head to the coordinates X: 76 Y: 40.

How to find Thaniel’s other half

Travel to the House in the Deep Shadows to find Thaniel’s other half. If you’ve unlocked the Shadowed Battlefield Waypoint, head there for quick access. Otherwise, head to the above coordinates X: 76 Y: 40 or southeast from the Last Light Inn.

Meeting Oliver, Thaniel’s other half: Hide & Seek and dialogue progression

In the House in Deep Shadows, you will run into a boy named Oliver. If you’ve already discovered Oliver, you know he will ask you to play hide and seek with him, and you must win at playing Hide and Seek. If you haven’t, play Hide and Seek.

Tip:

Make sure you have a working Moon Lantern or Pixie Blessing as you are completing objectives in this quest.

But you can talk to him if you’re returning to this location or just finished playing Hide and Seek. And you’ll gain access to some new dialogue after he asks you to play with him.

Of the dialogue options, choose the first one, where you tell Oliver that you know who he really is and that he needs to return to reunite with Thaniel since he will die without Oliver’s presence. The two are one and the same; Oliver is simply the shadow version of Thaniel.

Of course, Oliver won’t like this, and he will say you can’t make him stop playing. He will run off into a portal, which you must enter to follow him.

Here, Oliver will summon his shadow parents and dog and trap himself in a magical bubble called the Nightdome, and you will enter into a battle with various creatures.

How to beat Mommy, Daddy, the Dogs, and the Dome

To get to Oliver, you must defeat the creatures in your path, and the best way to do that is to beat the parents first, then the dog, and finally damage the dome enough so Oliver is forced to come out.

As they’re shadows, they aren’t too difficult to defeat, and killing them also weakens Oliver’s bubble, which has 300 health, but there are a few tips and tricks you can use to beat them with ease.

  1. Select one high-damage-dealing person, like a Sorcerer or a Warlock, to clear the dogs.
    • Magic Missiles is the best and most efficient ability to clear the mobs because you get three missiles, and they’re 100 percent guaranteed to land.
  2. The rest of your team will focus on the parents, starting with one, and when that one is killed, the other.
    • When one parent is killed, this will deal 60 damage to the dome. So, if you can quickly kill them both, you’ll deal 120 damage to the dome.
  3. Oliver will also create shadows of himself that you’ll need to kill. They only have one HP each, so you can use an AoE spell, like Fireball or Magic Missiles, to clear them.
  4. Use a light to ensure you can see Shadows.
  5. If any of your characters are a Fighter, like Lae’zel, use Action Surge to gain an extra action that turn, as this will help whittle down Mommy and Daddy’s health much faster.
  6. If you have a Barbarian, like Karlach, you can also use Frenzy to gain an extra action and deal more damage to Mommy and Daddy.
  7. Once you’ve killed all the shadows, you can focus your abilities and destroy the Nightdome.

How to convince Oliver to return to Thaniel

When the fight ends, you must convince Oliver to return to Thaniel. To do this, tell Oliver that with Thaniel, he will always have someone to play with, and he doesn’t have to be alone anymore. This will make Oliver see reason and transform into a real boy right before you.

Return to camp after Oliver disappears and speaks to Halsin. The Druid will say Thaniel is recovering well now that Oliver has returned. Within a few days, Thaniel will be as good as new.

Now, you can see Thaniel at your camp, and this part of Halsin’s questline is complete in Baldur’s Gate 3.

And, even better, this will help you increase your favorability with him if you want to romance Halsin later.
