Korra and Mako were working up from their unconsciousness as they stood up on their feet. They looked around to see a background full of white and nothingness. They wondered, what happened and how they ended up here. 

Korra: Man, what happened and where are we?

Mako: I don't know, for sure we aren't in Republic CIty anymore.

Korra then saw something surprising as she said to him

Korra: looks like we are not the only ones here anymore.

Mako: Huh?

Mako turns around sees everyone he has recognized. The females, Asami, Lin Beifong, Suyin, Jinora, Ikki, Opal, Pema, Kya, Zhu Li, and surprisingly Kuvira. Not only that there are the males, Bolin, Wu, Bumi, Tenzin, Varrick, Meelo, and Hiroshi Sato. They were also in this strange place just working up out of nowhere, finding no clue of what's going on.

Asami rushed over to Hiroshi and embracing him

Asami: Father!

Hiroshi embraced Asami.

Hiroshi: Asami! my daughter.......I'm so sorry. What I had to do what was right

Asami's tears came out of her eyes. After calming down from her crying, the daughter and father looked around seeing where were they. Korra and Mako shouted to the group as they waved. 

Bolin: Mako!

Mako: Bolin!

Asami: Korra!

Korra: Asami!

Team Avatar was glad to see each other as they were talking to each other. Lin on the other hand was next to Tenzin asking him

Kya: So, where are we?

Tenzin: I don't know, Last time I was heading out to get fresh air, and then suddenly we are here with my wife and kids. 

Opal: I don't remember being here? Where the heck am I?

Opal was very confused about what's going on here. She remembers she was helping Bolin clean up the mess that happened in Republic City. Kuvira on the other hand was confused as well as a few people were scolding her for her crimes. Everyone was talking to each other trying to figure out what is going on. That is until Korra shouted.

Korra: Enough!

This caught everyone's attention.

Korra: Now I don't know why we are here. We should be working together to get out of this place and get back to Republic City.

Kuvira: Korra is right, we can't be standing here and arguing our difference. We should start working together and find our way back to Republic City. 

Tenzin: Call me crazy, but I think we were here for a reason.

???: You are correct

Everyone got attention who spoke to them all of sudden. They turned around to see a figure stepping out of the shadow appearing to be a male wearing some sort of formal clothing. The only difference is that this human looks different. He didn't look like he is from the Water Tribe, Fire Nation, Air Nomad, Earth Kingdom, or the United Republic of Nations. Not to mention his skin was white and has brunette hair.

???: I see you want answers you see.

Korra: Who are you?

Servus: You can call me Servus at your service

He bowed down like a gentleman

Asami: Servus?

Servus: I have brought you here because my master told me to.

Kuvira: Your Master?

Tenzin: So that means you are the Servant?

Servus nodded

Kya: So we've been brought here into this place by your master?

Servus: My master is a god

Everyone was extremely shocked that the lord he served is a God. Both Korra and mako were shocked and surprised that this God brought them here and they wonder if they wanted to meet him

Servus: My Lord is genderless. It is very Omnipotent.

Lin: So, can we see your Lord?  We want some answers to why we're here.

Servus: Very well, follow me

Everyone followed Servus as he opens the door. When the door opens, it shines a white bright light. They step into the room and see everything that they are standing n invisible floor and all around them is a whole space.l

Jinora: wow.....

Pema: So beautiful.

Ikki's eyes sparkled with stars in her eye pupil.

Asami: I can't believe it. Who thought that something like this existed. So where are we Servus?

Servus: This is my Lord's home. This is his home

Bolin: So your lord is living here? No offense but it looks empty.

Servus: Sometimes he likes nothing here. But he has a special ability to do anything he wants by his choice.

Kya: I see what you mean.

Varrick: Alright, now how long until we meet your lord?

Servus: Very soon, now behave yourselves. We're almost there.

As they reach their destination, they see a throne chair. They see someone sitting on it. They approached it until they stopped by Servus and he approached it and he said.

Servus: My Lord, I have brought them as you asked

He said bowing down before him. The lord he reffed to wear a dark armored suit. Its eyes glowed shining blood red. He also has a red ruby on his chest. He raises his head to see they have arrived. Its name is Domini. 

Domini: Thank you Servus. You did a great job.

Servus: Thank you.

Domini then turned to the group.

Domini: So...you are the people of Earth? I am Domini. I am God of All Universes.

Everyone was feeling nervous to meet a real-life Godlike being. Not only that, his appearance was scary. Wearing a dark armored knight like he some sort of evil lord. After calming down, Korra stepped in and said to him

Korra: Greetings Domini, I am...

Domini: Korra of the Southern Water Tribe and the Avatar.

She was gasped by it's surprising that it knew her name.

Korra: You know me?

Domini: Of course, In fact, I know every single one of you. Ever since you were a fetus. Don't take it the wrong way. I've been watching you, your world. Your people have gone through many trials and challenges to reach their goals. From the 100 year war to Kuvira's invasion of Republic City. Now the reason to bring you all here is that I want to show you seething that you have never experienced for the first time.

Hiroshi: I don't understand

Domini: You will understand Hiroshi Sato. Now I will show you all

He then raised his hand into the air as the entire space just zooms in through faster than light. Everyone except Domini and Servus feels like they are being pulled in. Then they stopped and found something surprising in their eyes. They look at the planet that looks like their world except it's different. 

Asami: Oh my goodness!

Suyin: Wow....is that?

Lin: Looks like the world we live in, but it's different.

Asami: I should've known. There are other worlds in the universe.

Kuvira: Ok, so you showed us a world like ours. It's nothing new

Servus: is that so?:

Kuvira: huh

Servus: look again.

She looked back to see something shocking in her life. Like her, everyone is shocked as well. They see a giant space navy ship floating in space.

There are also other spaceships and space stations flying above the Earth oribt. Everyone couldn't explain those things that came into existence. Asami on the other hand can kinda guess what they are. 

Ikki: Lord Domini what are those things?

Meelo: They look fun! 

Korra: What are those things?

Asami: I'm going to guess they are some type of airship that can fly past this planet's orbit and into interstellar space. The only difference it looks so advanced compared to ours.

Domini: You are correct Asami. The ship is a military navy starship. That is going to a distant star in the galaxy. About 1000 light-years away.

They continued to watch seeing the starship moving then out of nowhere it just vanished into the deep dark space

https://youtu.be/tAWd9lrl1lo

Asami: What just happened? Where is the ship?

Domini: The ship is currently in Hyperspace. Basically, they are going FTL. Or known as Faster Than Light. 

Asami: Faster than...light? That's impossible!

Domini: Not to these people. They created these ships. They are made by humans of that planet is also called Earth.

Everyone was shocked to hear this revelation. There are also humans on this planet that is also called Earth. 

Bumi: What? there are humans living in that world called Earth?!

Tenzin: Humans who live on that world have made those ships? How though?

Korra: I don't get it? Another race of humans? Advanced ships? Please, Lord Domini. Can you explain to us what is this about?

Domini: I shall explain everything you need to know

https://youtu.be/S3wsCRJVUyg

Domini: That is all I can explain right now.

Korra: I see, so the human race on this Earth is different from our Earth. But they did achieve everything there. More surprisingly, Benders don't exist in this Earth.

Asami: They went through so many trials and challenges. Where they actually united as one to achieve space exploration. Their weapons have changed and all. 

Kuvira: No Benders? That is most shocking. Just wow. How do they live without it?

Asami: Science of course. 

Mako: They are living better lives than we are.

Bolin: I hope one day our world will achieve something like this.

Tenzin: There are different religions that worship different gods? That is something strange. 

Lin: The most common weapon they use is Guns? Or Firearms they say?

Suyin: They have much different Music genres like Classical, Folklore, Rock n Roll, Heavy Metal, and even Jazz.

Zhu Li: There are over 200 nations on this Earth. It looks like Democracy dominates the entire Earth. 

Wu: So there are no nobles, no aristocracy, that means no monarchy then.

Domini: Actually there was a monarchy, but they added something new to a stable monarch nation and it's called a constitutional monarchy

Wu: Constitaitonal Monarchy?

Domini: A System of government in which a monarchy shares power with an organized constitutional government. Take Japan for example. The head of the state is an Emperor but he is a figurehead so he had no exercising power on her own initiative. The one who has the real power of policy and decision of the government is called the Prime Minister. 

Wu: Really? Hmmm, maybe I should do that. Maybe I should just be a figurehead instead of having real power. 

Domini: Certainly, It would work just fine.

Mako was smiling at Wu seeing that is a smart thing to do. 

Asami: I am so interested in their history. Though I wish to see more about them.

Korra: I am up for it

Bolin: Me as well

Mako nodded for approval.

Kuvira: I would like to see what these people have done that we don't have.

Lin: Certainly then we can learn from them so we don't make that same mistake.

Domini: That is why I brought you here. 

Domini then snapped his finger as they teleported to a theater and they found themselves in an empty field filled with a small number of trees, and tall grass fields. Everyone was looking around to see where they are.

Korra: Where are we?

Domini: Ethiopia, 200,000 years ago. Humanity evolved from Primitive species of humans called homo Erectus. 

Asami: Evolved?

Domini: Correct Asami, On this Earth, Humans were evolved from this planet. Just like your planet. Humans evolved very slowly, and they are still evolving to this day. We call this Evolution.

Asami: Evolution......amazing! Something I should write down on.

Servus: Ah looks like we got some people arriving. 

They see a group of primitive humans with stone spears chasing down an animal. They were making grunting noises. After they killed the animals they were cheering and celebrating that they got food.

Asami: poor little animal!

Servus: well they had to eat to survive. 

Domini then took them a few hours later. It was nighttime they can see they were cooking the same dead animal with fire. 

Kuvira: so they didn't have homes or anything?

Servus: Actually they did, they slept in caves before homes were invented. 

After they were done eating, they went inside the caves to hit the hay. 

Then Servus watched beeped. 

Servus: Ah, My lord, it is time.

Domini looked at Servus

Domini: Alright everyone it is time to take you to a more comfortable place.

Then with a snap of a finger, Domini teleported them to a theater and they found themselves sitting on chairs. Domini and Servus are standing in front of them and behind those men is a huge screen. He continually said to them.

Domini: You are in a theater room created by me. In this room, you will be reacting to many different timelines in this Earth's history. Now before we began, would you like any food and drinks?

Korra: Yes, please

Mako: I'm in by the way, what do you call these humans?

Domini: We call them Terrans. 

Asami: Ah..ok..I'm excited to learn about them! I can't wait to learn about their scientific achievements.

Tenzin: I'm excited to learn about their religions and traditions

Kuvira: I want to learn about their political ideologies. I mean I bet on Earth there is a nation out there they have the same ideals as me.

Domini and Servus were quiet at first then they spoke 

Domini: ok.....anyways, are you guys ready?

All: Yes!

Domini: Ok, it is time to react to Earth's History.
