How to Complete Caribert Archon Quest in Genshin Impact 3.5
Caribert Archon Quest will require you to go to Port Ormos in Sumeru, where you will meet Masrur, the Deputy Post Master. You will then need to talk to him, and he will give you a letter. When you read it, you find out that it's from Kaeya, who is currently in Sumeru and wants to meet you at Djafar Tavern the next afternoon.
You will then have to wait till 16:00 to 18:00 the next day, and you can fast forward this time by using the Time feature in the game. Afterward, go to the Tavern, meet Kaeya, and talk to him. After having a long chat, he reveals that he is Khaenri'ah and his surname is Alberich. Right after that, Dainsleif makes his appearance, and after a short dialogue, he reveals that Kaeya is the descendant of the Abyss Order's founder.
After chatting, Kaeya leaves you and Dainsleif when you and Dainsleif decide to find out more about Loom of Fate. After completing the dialogue, go to the location marked in Gandharva Ville on the map below.
Talk to Dainsleif and investigate the empty house, and when you don't find anything. Then, enemies will appear outside the house, and you will have to beat them. After that, Dainsleif will leave and will ask you to wait for him at the camp.
As it gets darker, you will sleep, and after you wake up, you hear a sound coming from the house. Then, you will have to go to the house where you will meet a person, and you will have to talk to him. Afterward, go inside the house with him, and you will find a hilichurl lying on the bed.
Talk to the person, and he will reveal that his name is Eide, a Khaenri'ah and that hilichurl's name is Caribert, and he is his son who was cursed by the Gods. Have a long dialogue with him, and then he will ask you to accompany him. Go outside the house and talk to Eide, where he reveals that he wants to cure Caribert using the medicine, and after a chat, you will have to prepare the medicine at his crafting table.
Then, you will have to go to the Statue of the Seven near you, which is marked in the mini-map, and keep in mind that you won't be able to teleport during the whole quest. Once you reach there, a series of dialogues will initiate.
Afterward, go back to his house and give that medicine to Caribert. Again after a long dialogue, Eide will ask you to bring water from the waterfall marked in the minimap as the medicine hasn't worked yet.
Go to the waterfall and bring the water to Eide, and after a chat, he will ask you to wait there. After that, the enemies will appear again, and you will have to beat them. After that, talk to Edie again and go to the Statue of the Seven again. You will then spot a hilichurl going somewhere that you and Eide think is Caribert.
Follow the hilichurl, and you will see that it's not him, but the behavior is suspicious. You will then have to follow the hilichurl, and you will reach a domain, Unknown Sanctuary.
Enter the domain, and you will find hilichurls bowing and praying. Go forward and beat all the enemies and hilichurls. On the way, you will see yellow-colored runes that you will have to pick. Two of them will be available easily, while the last one will be in a locked room.
To open it, you will have to take the stairs on the left side of the second rune and interact with the mechanism there to open the door of the room.
Then, go back to the space from where you entered the upside-down room through the teleporter and follow the direction to find another teleporter that will take you to the room of the third rune. Pick it up and jump down to the platform under it from the gate that just opened. Go to the center of the space and place all the runes in the polygon structure.
The gates will then open on the floor, and you will have to fly down, where you will encounter the new Abyss Herald: Frost Fall. Then, you will have to beat him; talk to Eide.
After that, go in the forward direction and enter the big door. You will then reach a big space, a cutscene will begin featuring a giant purple-colored crystal, and after a series of dialogues, you return to Eide's house.
Then, you will talk to Eide again and give the medicine to Caribert, which will work this time. After that, complete the next set of dialogues and go back to the Unknown Sanctuary again. Go to the big space again where you saw the giant purple-colored crystal; however, this time, it won't be there.
Talk to Eide and go back to the house. You will not find Caribert there, and after talking to Eide there, go to the marked locations in the minimap to find him. There you will meet Forest Rangers, and after talking to them, go to the next marked location where you will find Caribert, and a cutscene will begin.
After that, you will wake up straight in Eide's house as you got unconscious, and then you will have to complete another dialogue with him, and he will call you the Prince of Khaenri'ah. After that, you will look into the mirror and see your twin in it, and then Dainsleif and Paimon will wake you up.
You tell them about your dream, and after that, you have a long chat with them. Dainsleif will then part his ways to search for more information, and the Caribert Archon quest will be completed.
