The Start of Something New

Morning came, and Allen found himself unable to sleep, distracted by his new sister's delicate features and the way her hair spilled over the pillow. She looked so innocent and vulnerable, like she needed someone to protect her, and it only made everything feel more erotic.

As Allen lay lost in thought, Eula began to stir beside him. Not wanting to make her uncomfortable, he pretended to be sleeping and let her decide whether or not to talk.

Eula woke up and quickly left the room, her face flushed with a smile. The scent of breakfast soon filled the air, prompting Allen to get up and dress.

"Good morning," he greeted Eula, trying to hide his fatigue.

"Good morning," Eula said, turning away from the stove and smiling brightly. "You can sit down. Give me a minute. It's almost ready."

Allen took a seat and surveyed the table, which was filled with milk, orange juice, bread, honey, and butter. Shortly after, Eula arrived with pancakes and placed a plate in front of Allen. "Bon appétit," she said.

As Allen began eating, he felt uncomfortable with Eula's intense focus on him. She was fixated on watching him eat, rather than her own food, with her arms on the table and her hands under her chin. She purred happily as she observed him.

"Eula, I can't eat with you looking at me like that," Allen reprimanded gently.

"Sorry!" Eula quickly broke her posture and returned to a more refined stance that suited her usual demeanor. "But I couldn't help it. You're so cute when you eat!" She broke into a smile again.

Realizing that he had been worried needlessly about Eula's feelings, Allen came to a conclusion. 'I'm an idiot,' he thought. 'She only sees me as her long lost little brother and wants to spend all her time catching up. But I need to find a way to address this obsessiveness of hers.'

Having finished breakfast, Eula cleared her throat and asked, "So, Allen. What are your plans for today?" Her eyes shone with hope as she waited for his answer.

"I don't have anything planned," Allen replied. "I need to inform the guild about the completion of the commission, but I can do it later. We can take it easy today. I want to get to know you better."

"Sure!" Eula's face lit up at the offer, and that's what they did.

The two of them spent the day leisurely strolling around the area while sharing stories about their lives. Eula talked about their parents and how cool and beautiful they were. She also shared how their mother left the clan to be with their father and that she never regretted it.

"When you were born, you were so adorable!" Eula exclaimed. She went on to talk about how happy she was to have little siblings and how she would read books and sing to them to help them fall asleep.

"He was my teacher, but he was also a bit of a savior to me," Eula explained. She shared how her teacher was able to convince her uncle to let him leave the clan even at her etiquette classes, and teach her himself. He would always come to teach her along with his granddaughter, treating Eula as his own.

"She was always trying to follow me," Eula complained about Amber. She shared how Amber always tried to stick with her, even now that they had grown up, always trying to improve her image and make Eula meet more people. Although Eula complained, it was evident from her face that she was glad to have such a precious friend.

"My brother was quite similar," Allen started talking about his time in Inazuma, mentioning his friends Tomoki, Ayaka, Sayu, Kazuha, Sara, and his chess friend Kokomi.

Overall, their conversation was cheerful and light-hearted. They both wanted to share only the good parts for now. Allen avoided talking about Snezhnaya and the Fatui, and Eula avoided talking about her time in the clan and the sadness of losing them. Their sibling relationship was just starting, so there was no need to rush. There would be time to tell each other the truth later.

In the end, they finished the day by dancing a little before saying goodbye.

"You can sleep here tonight too," Eula offered.

"No, I think it's better not to rush," Allen replied. "I don't think I can stay up as late as I did last time. Let's meet again soon."

"Yes," Eula smiled. "You will always have a place here. If you ever need any help, I'll always be here for you."

"Thanks," Allen smiled and turned around. "Goodbye... sister."

Eula's eyes widened as she heard him call her sister. Her smile grew, and she exclaimed, "Goodbye, little brother!"

Allen returned to Mondstadt, passing over the Adventurers' Guild, telling Katheryne that the commission was completed before returning to his room.

Overall, it had been quite the rare days and experiences but it has been an enjoyable time, but he couldn't avoid being a little warry about all 'Could we really have a healthy sibling relationship? With her being a knight, I really doubt that I would be able to share the truth behind my activities with the Fatui'

Allen looked over his Delusion before turning to the bed and falling sleep. It has been quite the tiring day.

...

Some weeks passed and Allen discovered that having a new sister was quite reprimand for his work. Eula kept her distance when he was at Mondstadt or working with others like Fischl, not really wanting to make the relationship known and Allen being hated by the citizens for being a Lawrence. However, as he left the city, Eula was always waiting for him, tagging along at any commission and wanting to spend more time together.

This way, Allen's movements were quite limited, especially as he found that Eula was quite the good scout, being able to trace trails extremely well. If Allen wanted, of course, he could slip away, but it was quite the hassle.

It was after some weeks that he finally had some time alone as Eula was in charge of a recognition away. So Allen took this time to do something that he was postponing.

Allen directed towards Dragonspine, reaching the place where Durin's heart lay. Allen approached the heart, but ignored it, going at the back of it where a seemingly normal rock was.

Allen made a light cut on his hand, blood surging from it and planted his hand over the rock, this reacting and opening the entrance of the domain.

'As I expected. This is also a Lawrence's family Domain, being opened by the bloodline of it.' Allen thought 'Most probably Dottore's vial contained the blood of a Lawrence.'

Allen crossed over the door of the Domain and directly appeared in the wide final hall. Seemingly, as he had already conquered it, there was no need to complete it again 'But it makes me wonder the truth behind these domains, being capable of even knowing the difference between my normal and Columbina mode.'

Allen looked over the door, knowing that nothing will have been left after Dottore destroyed most of it 'But these kind of mechanists are only opened by true bloodline...' Allen remembered how Dottore easily opened the door after drinking some vial '

That might be one of his abilities, being able to alter his bloodline, making at least momentarily be detected as a Lawrence. But that wouldn't be his Delusion's ability as I did not detect any use unlike the time against Ursa. I need to learn more about him and prepare for the future, I really can't trust him' Allen decided before turning over the frozen tree.

Allen reached the tree and summoned his Glacial Seal and as he expected, the tree reacted to it, defrosting, twisting over itself and falling to the ground forming a flower bud.

"When nature conquers you. Improve and conquer it again" A voice resounded over the hall and the bud opened, forming a very similar flower than the other domain and revealing a weapon floating over it.

It seemed to be a simple sword, quite the thin one, the only special being the blue intense color of the sword and a empty hole in its handle.

"Da Vinci Blade" Allen read the inscription of the sword, showing its name.

Allen took the blade with curiosity wondering if it was a true treasure and praying to be a 5-star compatible with him. However, just as he gripped it, a frown appeared on his face and after swinging it to test it as a blacksmith, the frown became even deeper.

"Let it be 5 stars, with this quality it would be in the lower end of a 4 star." Allen discovered "There's not even elemental power in it." Allen cursed, comparing it with Eula's Song of Broken Pines.

"Whatever" Allen sighed as he made the last test, using his Elemental Skill on it. This caused the blade to glow brightly and a smile appear on Allen's face "Interesting. I can really use it."

*BRRR* Suddenly the domain started trembling "An earthquake?" Allen quickly left the Domain too used to having seen in films traps and autodestruction be activated after taking the treasure. However, once he was outside, he discovered that is wasn't only the Domain, everything was trembling.

Leaving the cave and going outside, Allen was able to discover the culprit behind it. In multiple directions, more than 70 black pillars of what seemed to be Abyss element rose from the ground and pierced the sky, seeming to announce the destruction of the world.

It wasn't long before the pillars disappear and with it the earthquake, but Allen was sure that something had changed over Teyvat, he could feel it. "Aether had recovered."

...

On a floating island, drinking some tea over a table, Alice looked at the black-purple pillar "So it has finally started again. Quite earlier than I thought." She said calmly before sighing "I will be quite busy from now on."
