Albether

"Albedo sure is interested in you, though."

- Paimon to Aether in The Chalk Prince and the Dragon event

Albether is the slash ship between Albedo and Aether from the Genshin Impact fandom.

Princeps Cretaceus
In Albedo's Story Quest, in Act 1 of the story quest, Aether meets Albedo at Dragonspine with Rosaria who brought Aether to see Albedo. When Aether first meets Albedo, he was seen sketching but the hilichurls then noticed Aether so Aether had to defeat them. After Aether defeats the hilichurls, Albedo asks him who he is and why he killed the hilichurls. He thanks the gods that he finished his sketch when Aether asks him why he was drawing hilichurls, Albedo shows him his sketch to give him a clue. Albedo states that it seems Aether was looking for him. Albedo tells Aether that he came from afar which is correct. He also says that if he could procure his assistance, Albedo thinks the research would benefit enormously. Albedo says that he needs Aether's assistance. So Aether heads to the test site and Albedo asks him if he has any extra organs like a second heart or a fourth stomach. Then, Albedo makes Aether fight slimes to complete the experiment.

After Aether defeats the slimes, Albedo says that he'll take Aether to his campsite and that they can gather Starsilver Ore on the way. After they collect the Starsilver Ore, Aether takes a potion and drinks it from the desk. Albedo says that the result was a very positive one at that. The second experiment is for Aether to cook food, so after Aether cooks the food, Albedo says Aether seems well-versed in the science gastronomy. Aether uses his elemental sight to find the lost items as Albedo said. Aether then heads to the next experiment. Albedo tells Aether to jump off a small mountain as that is where the experiment is. But instead, Aether glides until the experiment was finished. Aether then participates in the final experiment, an intelligence test. Afterwards, Albedo and Aether both return to the campsite. When they arrive at the campsite, Albedo tells Aether that he is very human.

The Chalk Prince and The Dragon
In Act 1: Festering Desire, Aether meets Albedo again at his campsite after meeting Sucrose. Sucrose told Aether that she thinks Albedo is keeping a secret from her. Aether then confronts Albedo about it to which Albedo reacts confused and tries to change the subject. He gives Aether a sword called Festering Desire. Albedo wants to gather more data from the sword so Aether fights some enemies. After Aether fights the enemies, Treasure Hoarders appear. The Treasure Hoarders seem to know the sword as the Treasure Hoarders said "Hand it over" which is probably referring to the sword so Aether has to fight the Treasure Hoarders. After fighting the Treasure Hoarders, Aether looks sad at Albedo thinking that he stole the sword but Albedo responds that he didn't steal it.

In Act 2: Archon's Rival, Aether meets Albedo at his campsite again. Aether tells him that he made progress with the sword and the sword seemed to glow a bit. Albedo tells Aether that the sword grows stronger as he uses it in battle. Albedo then says that he investigated an area nearby and he discovered some unusual signs so they went to the area and saw a bonfire and a camp. Then the both of them come across Treasure Hoarders again but not just the Treasure Hoarders, the Fatui as well. After Aether defeats the Treasure Hoarders and the Fatui, Albedo says that perhaps they saw Aether using it on the mountains. Aether investigates the ley line disorder and fights some enemies. As the sword grows stronger, Albedo then tells Aether that they don't have enough infomation. If they wish to understand more, more data is required so this is where Aether comes in.

In Act 3: Raiders Amidst Snow Mist, Aether meets Albedo but outside of Dragonspine with the Branch Manager of the Adventurer's Guild. Albedo isn't interested in adventurers but he is interested in Aether due to his researches. After Cyrus leaves, Albedo and Aether head partway up the mountains but come across hilichurls while the both of them are chatting. After fighting the hilichurls, one of the hilichurls runs away with Albedo's sketchbook so Aether decides to try and get it back. When Aether gives it back to Albedo, Albedo says it was alright as most of the sketches were still intact. Albedo then says if he wants to know why he trusts him, it might be because of the "unusual" ones.

In Act 5: Afterword, Aether then meets Albedo at his campsite. Albedo thanks him and says that he knows he could count on him.

Windblume Festival
In Act 3 of the Windblume Festival, Aether is willing to help Sucrose so Aether goes to Albedo outside of Dragonspine because that's where he is. Albedo reads the alchemical recipe but he doesn't believe that this is a recipe for a Windblume. Albedo tells Aether to gather the ingredients listed. After Aether gathers the ingredients and goes back to Albedo, Albedo starts working on it. After that, Aether gives it to Sucrose in Mondstadt.

Midsummer Island Adventure
Upon speaking to Albedo after the Midsummer Island Adventure event's main story concludes, he will smile at Aether if you speak to him in the Archipelago, stating that he is pleased to see him again and insists that he never knew that Dodo-King was Alice.

Quests

- Albedo to Aether after he left.

Voicelines
"I am Albedo, Chief Alchemist of the Knights of Favonius. You carry the aura of the stars, interesting... I would like to study you, if you do not mind. I'm certain we will have many opportunities to be alone in the future."

- Albedo's Voiceline: Hello

"Good night, you go ahead and rest. I will just finish one last experiment before bed... If you are interested in the results, I can discuss them with you tomorrow."

- Albedo's Voiceline: Good Night

"You... want to accompany me while I experiment? I'm honored. Oh, don't be nervous. My experiments may be dangerous, but no one gets hurt... most of the time."

- Albedo's Voiceline: About Us: Experiments

"Would you oblige me by serving as my assistant? After observing so many experiments, you surely know a good deal about alchemy by now. Relax, we will work together. I don't think you will have any problems. I have faith in my ability to instruct you, and even more faith in your exceptional talents."

- Albedo's Voiceline: About Us: Assistant

"There's something I've always wanted to ask you, but feared rejection and disappointment... Eh-hem... I am very interested in your little floating companion. May I borrow her to investigate for a short while?"

- Albedo's Voiceline: Something to Share

"Happy birthday. You look especially happy, would you mind if I sketched you? The capacity of our brains is limited, so we are bound to forget things. But when an image is transferred onto paper or canvas, the sketch becomes an extension of our memory. We can remember that past feeling when we later look at the sketch."

- Albedo's Voiceline: Birthday

"Albedo is the step in which change begins. Clearing away the excess so we can take on all the knowledge that is available. Would you like to investigate this world with me?"

- Albedo's Voiceline: Feelings About Ascension: Building Up

"Rubedo in alchemy refers to the refining of feeling. I feel the refining of my own emotions is also thanks to you."

- Albedo's Voiceline: Feelings About Ascension: Climax

"Citrinitas is the final stage of the alchemical transmutation process. The meaning of the object being transmuted has finally been brought to light, becoming gold and revealing its true value... I too have found my own meaning."

- Albedo's Voiceline: Feelings About Ascension: Conclusion

Fanon
Albether is a semi-popular ship among the Genshin Impact fandom. Albether's main rival ship is Kaebedo, which is Albedo's most popular ship and Xiaother, being Aether's most popular ship. In other cases, Albecrose can also be one of Albether's rival ships. Albether is also the 2nd most written for the two on Archive of Our Own.

Albether has gained lots of attraction from the 1.2 Dragonspine update, it also gained more attention of what Albedo said at the end of Act 1 in his story quest, being that the thing that Albedo said was "If one day, I lose control... Destroy Mondstadt... Destroy everything...can I rely on you to stop me?", making people make edits as well of Albedo and Aether, it also gained attention as well from the 1.4 Windblume Festival update.

Trivia

 * Both of their outfit names have a connection with the stars (Rising Star for Aether; Newmoon Starlight for Albedo).
 * In his birthday letter, Albedo says that “it is indeed a joy to gather and celebrate with important people”, and attaches two drinks to it, perhaps assuming that no one else is invited except Aether.
 * There are many confirmations of Aether representing the Sun, such as several symbols of the sun on his outfit (the elemental one on his chest, stylized sun rays on the top of the back of his cape, the alchemical symbol of the sun (☉) a little lower), the warm color scheme, him being a summer person and generally more expressive (than his twin sister); In turn, the albedo stage symbols include silver (Albedo wears silvery elements on his arms), the Moon, white rose, etc.
 * The alchemical symbol of the sun also corresponds with gold.
 * Citrinitas (the final stage of the alchemical transmutation process in the game) is often called the wedding (or the union) of the Sun and Moon.
 * Aether is the only person (excluding Paimon) whom Albedo trusts enough to tell the secret of his origin without much hesitation.
 * The Traveler is the only one who pays close attention to Albedo's neck and the star mark.
 * Albedo offered an analogy stating that he is a perfect rose, and Aether is his gardener — the only person in all the world who can tell the difference between him and his doppelganger(s).
 * Klee doesn't call Aether “Mr.” (similar to Albedo and some others in that case, the English translation being wrong), most often she just calls him her older brother. Aether cares about her too, agreeing that he loves her and thinks of her as a friend.
 * The Traveler is also the person that Klee thought about and went to when she didn't manage to find Albedo.
 * Out of a huge number of people (Klee, Jean, Kaeya, Diluc, Barbara and Razor), Albedo states that he would prefer to have a conversation with Aether specifically, and adds that the Traveler is intelligent and he likes “to talk to intelligent people”.
