For the first time since Otenko arrived to Equestria, Twilight Sparkle was given an idea about what was unfolding. She knew that if what Otenko said was true, the Immortals would go after Princess Celestia and Princess Luna. Twilight knew that the Immortals couldn't be ignored.
--------------------------------------------------------------------------------
As a lot had happened that day, such as the Immortals' invasion and the kidnapping of several of Ponyvilles' residences, Twilight's friends went home to get a good night sleep since they all had to pull their weight and repair the town the next day. Twilight couldn't sleep though. She felt responsible for letting the Immortals leave with Spike, Rarity, and Sweetie Belle. Instead, she spent the night trying to learn what she could about Eternal Beast, Sleipnir.
"AGH! I CAN'T FIND ANYTHING ON THIS THING!" Twilight shouted in anger.
"I'm sorry that I can't help as much as I'd like to." Otenko said with regret. "Even I don't know too much on Sleipnir. I've had first hand experience with two other Eternals, but the differences between them was so great that I doubt it could help us now."
"What kind of differences?"
"Well, I suppose the biggest difference is the way they've been sealed. The first Eternal, called Jormungandr, got sealed within the earth. The second, Vanargand, got sealed away on the moon. So unless Sleipnir is somewhere within your Sun, I have no idea where it is."
Twilight took what Otenko said as a point in to a direction. Since the Immortals planned to break the seal on the Eternal, she figured it would make sense if she figured out where Sleipnir's seal was. That said, she decided that if she focused on finding the seal, information on the monster wouldn't be practical. Of course, figuring out where Sleipnir was seal was something equally as hard to learn about. She thought back to the chant Otenko taught her.
"The gate will open when the Sun and Moon merge, but only discord can hold back the scourge." Twilight said to herself. "I wonder if Discord would know anything about this. He is the king of chaos after all."
"Excuse me, but what was that about a king of chaos? Otenko asked.
"I'm talking about Discord. He's arguably the most powerful individual in Equestria. Maybe even the world. He once tried to take over and plunge the world into chaos, turning places upside down, made clouds rain chocolate, and essentially changed all laws of physics. He's still somewhat evil, but he's on our side now. He sometimes comes to turn our water into wine for no other reason than to see all of us tipsy, but it could be worse."
At first, Otenko didn't know what to make of what Twilight said, but after it became clear to him that she wasn't lying, he nearly had a stroke from the shock. He couldn't believe a word he heard. He didn't believe that there was someone who was literally called Discord.
"ARE YOU TELLING ME SUCH A BEING EXISTS? THIS CHANGES EVERYTHING!" Otenko shouted.
"So you think Discord does know something?" Twilight asked.
"All this time, I looked at the word discord in the chant as just a word meaning chaos, so I assume it had something to the Dusk Sisters. I didn't realize Discord was the name of someone. We must see him right away!"
After finally getting an idea on what to do, Twilight knew it was an important to see Discord as soon as she could, but she didn't actually like the idea. After all, it was Discord they were talking about, and while Otenko had personal experience with Eternals like Sleipnir, Twilight probably had even more experience when it came to Discord.
"Oh! And I have another task for you." Otenko said. "Before we go out to find Discord, it's very important that we know who is in your town and who isn't."
"Really? Why is that important?"
"Think about it, Miss Sparkle. There are three Immortals in this world who can take over bodies. How many have we seen been taken so far?"
A very scary thought went into Twilight's head. Mjolnar took over Rainbow Dash while Gungnir took over Rarity, but she had absolutely no idea who the youngest sister, Missel Tow, took. At that moment on, Twilight had more to worry more about than just Sleipnir's seal.
--------------------------------------------------------------------------------
The very next day, Twilight invited her friends back to her home to discuss her plans to deal with Equestria's newest threat. To figure out who else the Immortals took away, she sent the best pony to figure out who was in Ponyville and who wasn't.
"Alright, Pinkie Pie. Is everypony still in Ponyville?" Twilight asked.
"I just went all around town and talked to every single pony I knew." Pinkie asked. "I saw Vinyl, Octavia, Bon Bon, Lyra, Derpy and the Doctor, Carrot Top, Colgate, that white pegasus that looks suspiciously like me...OH, and Dinky! She was with Derpy and the Doc-"
"Pinkie! Is everypony here?" Twilight asked with impatience.
"Huh? Oh, yeah. Everypony but one is here. I looked all around with my list of names, but I can't seem to find Pinkie Pie."
"Pinkie Pie, that's you."
Pinkie Pie gasped in horror from what Twilight said. "OH NO! That can only mean...THE IMMORTALS GOT ME TOO! AAAHHHH!"
In a state of panic, Pinkie Pie ran through Twilight's wall, leaving behind a Pinkie Pie-shaped hole, and ran down the street in a horrified state. Otenko and Applejack looked through the hole and watched the silly pink pony running away from nothing.
"Is your friend always this bubbly?" Otenko asked.
"Nah, this is what we call 'calm' Pinkie Pie." Applejack answered.
Twilight took a look at the list of names Pinkie Pie had to make sure there were no names not accounted for. She was upset when she found that, if what Pinkie Pie said was true, every pony was still in Ponyville. She had no idea who else the Immortals took away.
"Well, this stinks." Twilight said. "Now we have no idea who else is in trouble."
"I was afraid of this." Otenko said. "Mjolnar and Gungnir are always easy to expose. Missel Tow, however, is a completely different story. In fact, she may very well be the most horrifying of the three."
"How so, Mr. Sunshine?" Pinkie Pie asked after suddenly reappearing in the library.
While surprised by Pinkie's return, Otenko nonetheless answered. "The Dusk sisters are famous for taking over the bodies of any ordinary mortal they wish, but only one mortal, and they can not take over another until something forces them out of their new bodies. Missel Tow is slightly different."
"Different how?" Twilight asked.
"With her shadow tendrils, she can take over multiple beings in addition to her actual host body. Rather then fighting herself, she will force allies to fight each other until they're force to kill each other."
Fluttershy shivered when she heard what Missel Tow was actually capable of doing. "That sounds awful. Why would anypony want to do that?"
"She is the most the most insane of any Immortal I have ever met. As chaotic as she is though, she is rather sneaky and stealthy, often acting as a spy of sorts, so it's no wonder that we can't find her. I was really hoping that she wouldn't be hiding so shortly after coming here."
"Well, this is fantastic." Twilight said sarcastically. "We have an enemy who kidnapped Rarity and Spike, an enemy who can destroy the world, and now an enemy we can't even find."
"Surely we'll be able to find your Discord friend, right?"
"Of course." Fluttershy answered. "I'll have to show you all where he is though, since I'm the only one who knows where he lives."
"OOH! Bring me too!" Pinkie Pie demanded. "He still owes me chocolate rain!"
Twilight was thrilled when her friends volunteered to help her and Otenko find Discord. Right off the bat, she figured Applejack would try to come too, but Twilight had another idea.
"Applejack, since I'm leaving Ponyville for a while, I will need somepony to stay behind and make sure nopony else gets taken away. Do you think you can do that?"
"Well...if you think I should sugarcube, then...yes. My family definitely needs me right now, Ponyville could use some strong hooves and I'm betting Rainbow Dash will need to wake up with at least one of her friends by her side.
"Thanks Applejack." Twilight said with a smile. "I know Ponyville will need me, but I need Discord. Can't believe I actually said that, but I digress. Until we come back, I'm trusting you to keep everypony safe."
"You can count on me, Twilight. Honestly."
Twilight smiled knowing that Ponyville was in good hooves. With one of her most reliable friends staying behind to keep everypony safe, she felt she could worry less about her home and more on her mission to save the rest of the world.
--------------------------------------------------------------------------------
Thankful for having a friend like Applejack to watch Ponyville, the two mares gave each other a quick hug before heading out. As they needed Discord's help ASAP, Twilight prepared a saddlebag, along with Fluttershy and Pinkie Pie, and the three mares made their way out of Ponyville together with Otenko. Twilight wasn't sure if she was making the right choice in leaving Ponyville, especially so soon after an attack, but because of the situation, she had no choice. She knew Applejack could be trusted, so that was one burden off her shoulders.
On their way out, Twilight brought a letter to a courier pegasus who was standing right outside of a destroyed post office. She had a very important job for the stallion.
"This is the letter I want you to bring to Canterlot." Twilight explained. "Since I don't have Spike anymore, I need you to bring this to Princess Celestia as quickly as possible. There's never been a time we need the Princess more than now."
"Understood, your highness." The courier said before taking off to Canterlot, wasting no time to deliver the message.
With Ponyville in safe hooves and an emergency letter sent to Princess Celestia, Twilight tied up the last loose end she needed to deal with. Twilight and the group gave one last wave goodbye to Applejack and made their way out of Ponyville to find Discord.
"Psst. Twilight." Pinkie Pie whispered. "Five bits says that Applejack is the one the bad guys got."
"Pinkie...please be quiet for a bit."
Applejack knew that she had too much work to do, so rather than staying and watch until her friends were long out of sight, she ran back to town to help restore her home the best she could.
Everypony knew that they had to do everything they could to help and Twilight's courier pegasus was no exception. He flew to Canterlot as fast as he could to deliver the most important message he ever had to deliver. Unfortunately for him, something didn't want him to leave.
Down below, a large, black shadow rose from the ground and stretched up at an amazing speed and grabbed the pegasus before he could see what was coming at him. then, as quickly as the shadow mysteriously appeared, it disappeared as it brought the screaming pegasus back to the ground.
