Reena C. Anemoi, princess of Finality and harbinger of the wayward winds, found herself in a pickle. 

"Oh, this is a nice place," The predecessor of her beloved father, the Anemo Archon, Barbatos, said as the bard looked upon the rows of books in her pocket dimension's library. One of them, more specifically, her private entertainment library containing numerous books across the multiverse and gathered with the help of Lady Fuli. 

"Thank you for the delightful tea," Zhongli, A.K.A Rex Lapis, the predecessor of her alternate realities' father, said as he lowered the empty cup of tea. 

"Indeed, it is quite delectable," Beelzebul, the Electro archon, and her aunt(in another reality), said as she lowered her own cup with a small smile. 

Reena smiled at this while moving with grace as she refilled their cups while her cyan-green accented cloak over her dress danced with the winds that flowed from the cosmos and into the study. 

"Thank you, my aunt taught me how to make Tea," Reena said with a smile before looking down as she felt someone tugging on her cloak. "Yes, Lady Buer?" 

"Can I really look around here?" Nahida, also known as Buer, asked, her elf ears twitching rapidly as her eyes shone. 

"Of course, you can," Reena said as she smiled at how Barbatos helped Buer pick some books. "I deeply apologize for my blunder," Reena bowed toward the Archons. 

"It's fine, girly," Barbatos said with a smile as he turned to his pixie form and floated around Reena and rested on the harbinger's black-cyan-green-tipped-streaked white hair. "It's good to see that my successor has a beautiful daughter," 

"Thank you, Sir Barbatos," Reena said with a smile. 

"Now, now. Please call me Venti." The wind pixie said as he turned to his bard form and landed beside the girl only for Reena to pull out a shattered Vision crystal and for it to spread similar to a hologram projection. 

"It seems like most of the guests have arrived," Reena said with a sigh as the projection showed the current guests.

Lumine looked around inside the theater as she stood up properly. She was resting after a long day of adventuring with Paimon when she fell asleep and suddenly found herself in an unknown place.

"Lumine! Paimon!" Amber, her first friend in Monstadt excitedly hugged her, 

"Amber! It's nice to meet you," Lumine said with a smile, hugging the red-themed girl before smiling even more when she caught sight of Diluc helping Jean stand up while Klee sat on Albedo's shoulders as he stood beside Sucrose. 

"This one does not know this place," Cloud Retainer said as she stood in her human form beside Shenhe and Chongyun. 

"A theater?" Yun Jin whispered before smiling as she saw Barbara and Nilou approaching. 

"Well, well," Tortellini- I mean Tartaglia, said as he approached the group. The people were separated into several groups. 

Monstadt

Liyue

Sumeru

Inazuma

Snezhnaya

"It seems like everyone is here," Hearing the melodic voice, Ayaka who was on her way to Lumine paused as she looked at the black stone in the theater. 

Lumine watched in horror as a gateway opened in a similar fashion to when the Sustainer of Heavenly Principles stopped her and her brother. Shaking in horror, the winds danced gracefully as a beautiful young woman with white hair and black streaks dressed in a beautiful White dress with beautiful inviting sky-blue eyes appeared with her white cloak dancing leisurely on her. 

Taking soft gentle footsteps, the young woman gently walked down the air, effortlessly taking the attention. Sadly, each step that she took intensified the fear that Lumine felt at the eery resemblance of the sustainer and the woman before her. 

"Greetings, I am Reena Anemoi and I welcome you to my home, Archon Hall," Reena said in a gentle voice and curtsy, using the cloak she wore as a dress. 

"Archon Hall?" Rosa asked, skeptically looking at the girl while-

"A-are you lord Barbatos?" Barbara asked, causing Reena to shyly chuckle and rub the back of her head. 

"I apologize, but I am not Barbatos," Reena said, giving Barbara a gentle smile that snapped Lumine out of her fear. She reminded him of Venti. 

"Oh, I apologize for my rash actions," Barbara whispered, turning bright red while Reena just gave her a nervous smile.

"While I am sure that you have questions, I have to apologize to each and every one of you," Reena said, giving them all a bow. "I have already discussed things with your countries' archons and representatives and have reached an agreement with them," 

"This is another dimension, isn't it?" Dottore asked as he looked at Reena while Collei cowered behind Tighnari. 

"That is correct. I have made a simple yet significant miscalculation," Reena said as she looked at Dottore. 

"Where is Buer?" Wanderer, a.k.a. hat guy, asked, getting ready to fight Reena.

"Buer is on her way, she asked me to let her borrow some books," Reena said, looking at Wanderer. While it did not appear on his face, the princess of finality and remembrance saw the relief that Wanderer felt when Nahida, carrying a stack of books despite her size, entered the room. 

"Reena," a female voice said as a woman in pink kimono appeared in a flash of purple lightning. "What's happening? Why is there a barrier in the Archon hall?" The former Raiden Shogun asked her niece. 

"Makoto..." Beelzebul, the Raiden Shogun, whispered as she saw her deceased twin. 

"That voice..." Makoto turned around and her smile brightened. "Ei!" Makoto cried out, disappearing in a purple flash only to appear in front of her twin and hugged her tightly. "I missed you, Ei!"

"Makoto..." Yae whispered. 

"Yae! You're taller," Makoto said as she finished crushing Ei in her hug. "Oh, Reena! Come here," 

"I prefer to give you and Lady Beelzebul space." 

"Nonsense, Ei, I want you to meet my daughter, Reena," 

"WHAT?!" Ei and everyone asked, looking at the two. While the harbinger of the wayward winds did not look anything like Makoto, they saw the mannerisms that the two shared. 

"Lady Makoto, I love you but I am not your daughter." 

"My husband is your father's alternate version and that makes you my daughter too," Makoto said with a smile causing Ei to faint at the information. 

"While I appreciate that and I do love you for raising me, I am afraid that I must keep things simple," Makoto gave her daughter a pout. "Fine... Mother," 

Makoto smiled brightly as Ei woke up. 

"While we wait for the generator to gather enough energy, I have prepared entertainment for all of us. Food and drink will be provided," Reena said with a smile. "Please take your seats," 

While most of the people sat by each other, Lumine and Paimon sat in the front row with Ayaka, Amber, Nilou, and several pretty girls. 

That was until an ominous black curtain opened which slowly drained the light of the entire room as a figure dressed in a leather black cloak passed through. 

Xiao, the conqueror of demons, as well as the veterans of the archon war, paled and readied their weapons at the sheer amount of Karma that poured out of the curtain of darkness that the figure exited from.
