The day before the twins 17th and last birthday all celestials stop ageing when they turn 17 but Aether and Ganyu thought nothing of it. Seeing as they were both immortal beings they thought it was nothing special about your growth stopping entirely and neither did the twins so they all agreed they wouldn't celebrate it so Aether and Ganyu were sitting on the edge of one of the cliffs at Stormbearer Mountains at sunset Ganyu had placed Aether's head on her lap while they reminisced about the past.
"Hey do you remember our wedding? The way Cloud Retainer stared at me, I'm pretty sure that damn bird hates me." Ganyu gave him a light slap on the head.
"Hey! She's basically my mother, she raised me after my parents died."
"Fine, fine I'll lay off her. But Gannie why did you marry me? Let's face it you could do better."
Ganyu gave Aether a small smile as she said "No I couldn't, it was pure luck that I meant and was able to make all of these wonderful memories with you. I love you."
"I love you too."
The next day Aether and Ganyu were getting ready for the day with Aether putting on his belt and Ganyu adjusting her golden bell.
"Hey Aether, do you remember your 17th birthday?"
"Yes but it was Lumine's birthday too, and like the twins we have now we thought there was nothing special about your growth stopping completely so we didn't celebrate it either and luckily I was of normal height before my seventeenth. What about you Gannie do you remember yours?"
"No but I do remember that mine wasn't my 17th it was my 21st when I stopped ageing."
"Well it's time we should go hunt abyss mages it annoying as hell how to keep duplicating."
They walked into the living room and saw the twins Lumine, Childe and there 16 year old son Chilu.
"Hey why are you here?" He said as he hugged his sister. "Good to see you too Ajax."
"I just came to wish my two favourite twins a happy birthday seeing as it is their last."Lumine said looking at them.
"Aw thanks aunt Lumine you're the best!" They both shouted but before she was about to hug them but then they all received ived a migraine that made them all fall on their knees.
ATTENTION HUMANS WE ARE TIRED OF TEYVAT BEING UNDER YOUR RULE WE THE ABYSS WILL ENGULF THE THRONES AND TOPPLE THE ARMIES AND WE WILL TAKE BACK THIS WORLD SO IF YOU'RE PATHETIC ENOUGH TO FIGHT BACK THEN THIS IS WAR.
"This brings back bad memories." Lumine said while rubbing her head.
"Me too, Aether can I see in you other room please." Ganyu said with a shaky voice.
"Ok Gannie." They entered the next room. "Gannie is there something wrong you seem a lot worried than you usually do." Aether said with a concerned look on her face.
Tears flowed down Ganyu's face as she said in a broken voice.
"Sweetie I don't think I can go through another war I saw a lot of people die in the Archon war I can't bear the thought of the people of Liyue dying or even… lose you again."
"Gannie I will never leave you again whether it's a war or an apocalypse I will never leave you again I promise." He lifted her chin so she would look up at him and kissed her. They then walked back into the room where they found everyone waiting for them.
"Hey Brother do you remember when you traveled the world to find me and earned the respect of many armies and the leaders of those armies."
"Yes why?" He asked.
"Well if everyone in this room got the same message then it's safe to say that everyone in Teyvat did as well. So your gonna have to meet up with them."
"So wait wait wait you want me to go to each of the seven nations just to talk about some war?"
"Yes."
"Why do I let you influence my decisions? I'll be back in seven to eight days." He said as he sauntered off with a pout on his face.
MONDSTADT
Aether knocked on a door of the current Grand Master he was greeted with a 'Come in' as he opened the door he saw Kaeya, Lisa, Amber and Jean standing in a circle. Aether spoke up "You guys are talking about the message from the abyss aren't you." All four of them turned around at the unmistakable melody of Aethers voice. They all had a small smile on their faces but all knew there was no time for pleasantries. Jean started the conversation.
"Yes. Everyone in Mondstadt has received the same message and even the entirety of the Knights aren't big enough to fight off a whole abyssal invasion." Aether could see Jean was getting quite nervous.
"Jean, there's nothing to be nervous about all you have to do is…." 'Okay now on to Liyue' Aether thought the next day.
"Morning Ningguang I just wanna go home so let's make this quick. I know you all got the message fromm the Abyss so we need to discuss what we are going to do about it." Aether sounded quite tired and sad due the fact that he had not seen his wife in a matter of days.
"The millelith is an army of strong and experienced fighters but we are still limited if paired with multiple if not another army we should be able to hold our own in a war."
"Great! So all you have to do is…."
With every passing day he visited a different nation and he was not enjoying going all around the whole of Teyvat again for his sister (well and his wife and children and nephew but not so much Childe).
After seven days Aether returned he saw his family sitting on the sofa talking.
"I'm back." Everyone turned to Aether in joy but they quickly shut down by what he said after."Now let's start training."
