Suddenly what looked to be a maid walked over and said.

Royal maid  : oh my look at how big you've gotten. How is that?"

Dainsleif  : you and everyone here have been trap in this dark crystal for over 500 years. It's a long story we'll explain soon I promise"

Royal maid : the war....what happened?"

Dainsleif  : i......the war....."

Dainsleif seemed to not know how to break it to her and other Khaenri'ah people gathered wanting to know what happened to. But this was too much for dainsleif to bare.

,
So Lumine stepped in and explained everything to them.
And afterwards said

Lumine  : but we didn't truly lose Khaenri'ah can be rebuild and we can strive again. I know how confusing this must be but you can trust us. And the abyss."

The people looked at dainsleif and asked.

Khaenri'ah man : dainsleif can we trust them?"

Dainsleif  :....yes you can t-

Khaenri'ah woman  : how can we trust all o-

Suddenly some Khaenri'ah royal guards walked over and said.

Royal guard 1 : Of course we can. Captain dainsleif has never steer us wrong."

Royal guard : if he says there's good then they are. We should listen to him"

Royal maid : and we have our prince. The only members of royal alberich family"

Kaeya : huh?.......Dainsleif you're an alberich?"

Royal maid : he's your uncle."

Kaeya  : uncle?"

Dainsleif : ........we should look around and get situated first before speaking about this"

Royal maid : let me escort you to the castle since you'll be needing a place to stay."

Lumine: you all go on I'll help handle things here"

Later at the castle everyone walked in and dainsleif saw it was exactly how it was before the war. And Kaeya fell an overwhelming feeling of deja voo.

Like he had memories of the place yet couldn't remember a thing.

Kaeya  : dainsleif I want to speak with you alone"

Dainsleif  nodded and they both walked off from everyone.

Once away Kaeya asked looking at stuff.

Kaeya : explain Dainsleif"

Dainsleif  : .....your mother is my sister that's how I'm your uncle."

Kaeay : why keep that q secret"

Dainsleif  : .....it's a difficult stor-

Kaeya : Tell me"

Dainsleif : .....your mother died trying to protect you from the gods as they attacked Khaenri'ah. In the end she did but couldn't protect you from the curse and you were turned into a Hilichurl.

Your father survived and tried finding you and tried to cure you.

I found out at the end of him trying and I found it horrible to put that kind pain on you to experiment on you daily in hopes of curing you. Maybe his heart was in the right place but  his methods were wrong.

Bur in the end after he died you were cured and turned human again."

Kaeya : then how did I end up at the dawn winery?'

Dainsleif  : your memory wasn't good you were a child I didn't want to tell you about your parents fate.

And your mother dying wish was For you to be safe I couldn't care for you. so I told you I was your father and told you a fake story and left you at the dawn winery. Knowing Crepus could care for you.

I was friends with him so I knew him well before leaving you with him. I also gave you the fake name Kaeya. Your real name is caribert.

I was also trying to hide you from the abyss. Your mother wouldn't have wanted you to go down the path your father created.....I'm sorry I know this is a lot to process"

Kaeya didn't know what to think. This was all a lot to process too much to understand at once. Yet he felt angry.

Kaeya  : you couldn't have told me the truth?......or something different.......because what you said to me as a child couldn't have backfired any worse....."

Dainsleif  : I'm sorry if What I said caused something bad to happen there was a lot g-

Kaeya : get out of my face......"

Dainsleif  : Kaeya y-!?

Kaeya : I SAID GET OUT!"

Dainsleif  : ......during this time we need to work together"

After this Dainsleif walked away and Kaeya walked off to look around the castle  trying to understand everything.

Later Kaeya return to everyone and as it was probably late everyone found a place to rest up for the morning.

And as Albedo was in a spare bedroom laying down he suddenly woke up as the door opened and he saw Kaeya walk in and get into bed with him hugging him and burying his face into albedo chest.

Albedo : are you alright Kaeya?"

Kaeya  : no...."

Albedo  : what happened?"

Kaeya  : I feel sick......"

Albedo  : w....what did you do?"

Kaeya: ......I drank over 500 year old wine......"

Albedo : why?"

Kaeya: .....I'm sad....."

Albedo : are you drunk?"

Kaeya  : ......maybe......"

Albedo : why are you unintentionally almost poisoning yourself?"

Kaeya  : ......this is too much....."

Albedo  : I know it can't be easy......but no matter what happens I'll always be here. And Klee"

Kaeya  : yeah....."
