We're going back to the main storyline :)

(Y/N) POV -

We were roaming around Mond when we saw a green haired girl standing at Timaeus' shop. Paimon asked her where he was and she told us that he had gone to Dragonspine to help Albedo. I remember Albedo. He was one of the leading alchemists in creating my catalyst.

She said that we could help him in his research so we decided to go there. When we teleported at the base of Dragonspine, we saw Barbara trying to convince Rosaria to join the church choir. When she left Rosaria turned towards the rock we were hiding behind and demanded that we reveal ourselves.

We walked out and I waved at her and she calmed down.

"Oh, it's you guys. Guess I won't pry further. You need something?" she asked.

"We're looking for Albedo, think you can help?" Ae asked.

She said that she kept track of him and we could follow her.

Ae used his elemental sight and spotted Albedo's footprints. That's so useful. I wanted to try that but instead to showing me where the elemental traces were, my attempt caused all the footprints to get coated in a thick layer of pyro. Guess that kind of helps...

We reached a higher part of the mountain and saw him painting some hilichurls.

We tried to stay silent but they spotted us and attempted to attack us.

I somehow managed to write that we weren't trying to fight them on the ground and they left us. My translator can be OP at times.

"Why did you scare them? It's a good thing that I managed to finish my sketch" Albedo said.

One round of rambling that I wasn't paying attention to, he asked Ae to fight a bunch of slimes. I released some electro at looked at Ae.

"Y-yeah... about that. Can we fight something else?" Ae asked him.

In the end we found a bunch of whooper flowers and fought them.

"Hmm. Interesting. Both of you are unique but your fighting styles are too different. Aether uses anemo without a vision while Asmoday uses two visions, that too in a way quite different from others. Could it be that both of you are from different worlds?" Albedo asked.

I gave a small nod.

"Interesting. Hey Aether, do you have any extra organs? Like a second heart or a fourth stomach, or something similar. Also is this floating child connected to you in any way?" he asked.

"No" Ae responded. " And I fished Paimon out of a river."

"But if Paimon guided the elements towards you, that would mean she has enough elemental energy to blow up a small mountain" Albedo said.

"Uwah! Asmoday! I'm scared. Help me!" Paimon said as she hugged me, so I covered her using my wings.

"Wow! Asmoday, you have wings? Mind if I study them?" Albedo asked.

I agreed and removed my hoodie so he could study them. He looked shocked at seeing the scar on my neck but decided to ignore it as he studied my wings.

"Any unique properties about them I should know?" he asked.

"They are a lot more sensitive than rest of my body and heal slower too" I wrote.

He nodded as he studied them.

"Can I take a feather for further research?" he asked and I agreed.

After that we went to his camp for more detailed experiments.

"Timaeus, prepare the potion I requested while I do some more experiments with our friends" Albedo told Timaeus.

"So, Aether, Asmoday. Any unique powers you guys have that don't belong to this world?" he asked.

"The only thing I have is that I can control anemo without a vision, but it is a possibility that I could gain the ability to control other elements by touching statue of the 7" Ae told him.

"As for me, you know about the wings. I also have these weird visions that look different from others. I can regenerate at a high speed and can heal from serious injuries by absorbing organic material around me. My blood turns into red cubes and it starts to absorb any living thing around it. Then there is my catalyst, but I don't think it counts as part of my abilities" I wrote.

"Interesting. Asmoday, mind if I take some blood samples?" he asked.

I offered my hand and he took some blood which turned into cubes after getting out of my body, but wasn't attacking anything because I didn't have any injuries.

He asked Ae to try move a rock with his thoughts, or do anything else that isn't possible in this world but he couldn't do anything. He told Albedo that he could purify Divalin's tear drop crystals so Albedo gave him a sword which Ae purified. He said Ae could keep it and now we have a cursed sword with us that would make anyone other than Ae go mad.

Then came my turn.

I changed my catalyst into the Necronomicon and tried Awakening The Kandarian Demon.

I opened the book and it started chanting. (Yes this Necronomicon can speak)

Katra a'mistrobeen A'santa tande'ea manoan Manseez O'han on'sopar Soman'ta rosa Kanda Kanda es-tratta Mon'tose Er-grets gatt'nos Veratoos Amantos Kanda Kanda es-tratta Ta-thun hazan sobbar Er-grets gatt'nos Veratoos Amantos Kanda Kunda astratta Montosse Kanda Kanda tranya Verata mesartra Mistrobeen

It kind of summoned the Demon, but Teyvat's laws didn't allow it to exist for too long without a host... which we forgot... Sooo it died.

At least I can make myself an undead army if I need to :D

After getting rid of whatever the fuck I summoned, Albedo handed us two potions. Ae drank his and all he got was some discomfort. I drank mine and instantly regretted it.

I could feel the elemental energy flowing through me normally at first but it soon got blocked by Divalin's blood that my body absorbed. I felt small shards of blood moving in my body as I fell on the ground in pain.

Albedo started panicking and quickly gave me another potion but it didn't do anything. Soon the pain became unbearable as the cubes in my body started trying to absorb the blood shards. I could feel the corrupted blood trying to escape my body as it started to cover my wings, turning them red and black. I thought that it ended when my blood started going berserk and I started bleeding.

Soon, it absorbed some trees around me and I fell unconscious.

Albedo POV -

The travelers agreed to my request and are allowing me to conduct some experiments on them. When Asmoday removed his hoodie to allow me to see his wings, I was shocked. He had a mark similar to me on his neck, but his more like an old wound, like someone stabbed him, while mine's a kind of birthmark. I took one of his feather and kept if for further analysis.

After coming to Teyvat, Aether seems to have been weakened a lot. According to him, he had wings but can't use them anymore. Asmoday on the other hand, has a lot of unique abilities. I still don't know if it's because people from his world are able to bypass most of Teyvat's laws or that he was stronger and this is his weakened form. He allowed me to take some of his blood and we started doing tests to check if they can use any abilities other than the ones in this world. Aether was unable to do anything but he said that he could purify Divalin's tear drop crystals so I gave him the sword made from Durin's blood, which he purified so I allowed him to keep it.

Asmoday changed his catalyst into something he called the Necronomicon. According to him it's something special from his world. I was curious about how he managed to create something from his old world from the catalyst I helped in making, but didn't ask him about it.

He opened it book and it started chanting in an unknown language.

Katra a'mistrobeen A'santa tande'ea manoan Manseez O'han on'sopar Soman'ta rosa Kanda Kanda es-tratta Mon'tose Er-grets gatt'nos Veratoos Amantos Kanda Kanda es-tratta Ta-thun hazan sobbar Er-grets gatt'nos Veratoos Amantos Kanda Kunda astratta Montosse Kanda Kanda tranya Verata mesartra Mistrobeen

With every word, I could feel an otherworldly power growing. Soon something similar to a ghost was summoned but it couldn't survive the laws of Teyvat. Asmoday told us that it was a ritual called Awakening The Kandarian Demon, but he forgot that it needs human bodies as hosts and it couldn't survive in our world. According to him it could probably survive in his world for enough time that will allow it to find hosts but he isn't sure because of his amnesia.

After cleaning up, I gave them the potion I made. Aether's was pretty normal but some kind of crystal formed at the bottom of the flask. I couldn't find out what it was so I kept it aside.

Asmoday was again an anomaly. The elemental energy's flow was normal at first but it found some kind of blockage and it started to hurt him. I quickly gave him the potion I made for such situations but it didn't do anything.

"Albedo! Do something!" Aether shouted.

"I-I can't. The potion has stopped the elemental flow but whatever it managed to trigger hasn't stopped" I told him.

Soon small shards of blood started seeping from his body. It covered his wings and turned them black-red when his own blood started to absorb anything near it. I managed to save us by creating a small barrier from Geo.

When it calmed down, we saw an unconscious Asmoday. I took him close to the fire so he could rest. His wings were still black-red and not their original color. I quietly took another feather to research the differences while he rested.
