Author's Note: This story will take place in the year, Eight Fifty-Four. Eren's timeline. Until further notice.
"Hey, Eren. I need to know. Is this your timeline or not?" Ymir, the Jaws had asked Eren.
A few minutes prior, the Nineteen-year-old Eren recently transported himself, Frieda Reiss and Ymir, the Jaws within his current timeline. In the year, Eight Fifty-Four. They were standing on the capital grounds outside the of the castle, Mitras within the royal capital. There were gray clouds hovering in the blue sky and the sun was yellow.
"Yes. We're here. In my own timeline." Eren replied to Ymir.
"Yeah, but how do you know? Everything seems fine." Ymir asked, doubting Eren.
Eren then pointed his right hand upward toward the castle, Mitras.
"Hm?" Both Frieda and Ymir, the Jaws had saw Eren raise his right hand.
"Just look up there." Eren said.
Both Frieda and Ymir looked at the castle wall and spotted a large red flag hanging from the balcony. The large red flag had an insignia on it, which was a black rifle and a white rifle crossing each other in arms and also, a pair of blue and white bird's wings spread out behind the black and white rifles. That flag had represented the Yeagerist Movement.
'A flag?' Freida Reiss had thought as she had spotted a large red flag hanging from the balcony.
Eren Yeager had stared at the flag, momentarily and quickly knew exactly who could've done this. 'Just as I suspected.' Eren had then thought of his fellow Yeagerist companions.
"Hey, what does that flag even mean?" Ymir pointed at the large red flag.
"Is that a new Survey Corp. flag?" Frieda asked Eren, curiously.
"It's a Yeagerist flag." Eren stated.
"A Yeagerist flag?" Ymir asked. "What? Did you and your cult suddenly take over the government?" Ymir, the Jaws had chuckled.
Eren had remained silent as he knew what Ymir was asking was true.
Frieda then gasped then looked at Eren. "Eren, does that mean, you-"
"Freeze!"
Frieda had been interrupted by a random masculine scream from above. Coming from the castle rooftop. Both Ymir and Frieda then looked up to see a group of six Yeagerists jump down from the castle rooftop by using modern Vertical Maneuvering Gear. The Yeagerist group were dressed in black Survey Corp. uniforms and wielded rifles in their possession.
"Stop right there, intruders!" A tall masculine Yeagerist with short black hair and brown eyes named Drew had yelled as he aimed his rifle toward the three Titan Shifters.
"Where are you from?"
"Are you spies from Marley?"
"Because, if you are, then we'll show no mercy!"
"Answer the question!"
As the group of Yeagerists continued to interrogate the three Titan Shifters, Frieda Reiss had moved her body a tad bit closer to Eren. "Um... Eren? What do we do?" Frieda asked Eren as she looked at a few of the Yeagerists that pointed and aimed their rifles at her. She did not try to nor want to make sudden movements, because she was afraid to be shot, despite already being a Titan Shifter.
Drew gasped after hearing Frieda call Eren's name.
"Yeah. You got a plan?" Ymir asked Eren as she kept her right arm at her side and her right hand near her right pants pocket. Inside her right pocket was a short knife. "Cuz, if not, then I'm gonna-"
"Be quiet! We're the ones asking the questions!" An average height Yeagerist with sun bleached hair and brown eyes named Brandon demanded as he pointed his rifle at Ymir.
"Hold on. Did that woman say, Eren? As in... Eren Yeager?" Drew had asked. Then, he looked directly at Eren and saw his face. "Are you Eren Yeager?" He had asked, which caught the attention of his fellow Yeagerists. One of the Yeagerists had lowered his rifle only a few centimeters.
Eren did not respond toward one of the masculine Yeagerist with his words. Instead, he responded by blinking at Drew.
The tall Yeagerist named Drew, who had interrogated him had gasped after making eye contact with him. He recognized that sharp pair of emerald, green eyes from anywhere. He then gasped and looked toward his fellow Yeagerist comrades. "Everyone, lower your weapons! Lord Eren Yeager has returned!" He had informed his fellow Yeagerists.
"Lord Eren Yeager?" Ymir asked.
The other five Yeagerists gasped when they heard Eren's name be mentioned again. Then, they lowered their rifles they used to aim at Eren, Frieda and Ymir and quickly saluted toward Eren.
"We are terribly sorry, Lord Eren! We had no idea that it was you. At first, we thought that Marley or any other nation had sent more spi-" The tall Yeagerist with short black hair and brown eyes had informed Eren, while saluting to him.
"Where's Floch?" Eren asked Drew of Floch's whereabouts
"Oh, Floch? Well, he's inside of our new Yeagerist headquarters." The tall Yeagerist, named Drew had answered while pointing at the Mitras Castle. Both Ymir and Frieda stared at the castle, Mitras.
"Take me to him." Eren had ordered.
"R-Right. This way." The tall Yeagerist, Drew had done what he had been ordered by turning around toward the entrance of Mitras and begun walking toward it.
Eren had looked back at Frieda and Ymir, whom were behind him. "Stay close to me." He had told them, before following the tall Yeagerist with short black hair and blonde eyes. Frieda quickly nodded, then followed behind Eren. Ymir followed behind Frieda. As she did, she dug her hands into her pockets and turned her head left and right and glanced back at the Yeagerists behind her.
Within the Castle, Mitras...
A few minutes entering the castle, the tall Yeagerist continued lead the three Titan Shifters toward Floch Forster's current location. Which is inside the of the throne room where ceremonies would usually be held. As they walked the castle's royal hallway, the tall Yeagerist named Drew decided to open his mouth as he continued to lead the Titan Shifters toward Floch Forster. Ymir just continuously looked around, shifting her head from left to right.
"Again. I have to apologize. For our earlier actions." Drew said.
"It's fine." Eren said, brushing the interrogation off.
"Ever since when Marley had attacked, and when you disappeared, Eren... we, the Yeagerists had placed the New Eldian Empire high alert." The tall Yeagerist with short black hair and brown eyes had explained.
"Mmph," Frieda muffled to herself. 'The New Eldian Empire?'
"High alert, eh? Did anything happen since the island has been on high alert?" Eren asked.
Drew had thought for a moment. "No. Not since you disappeared." He raised an index finger while walking. "But, there was this one incdient when-"
As Drew had opened his mouth again and yammered on and on... Frieda Reiss had walked a tad bit faster toward and moved closer toward Eren's body as they walked. "Um, Eren?"
Eren slightly turned his head to the right and his right ear facing toward Frieda.
"What is the New Eldian Empire? I'm curious to know." Frieda whispered.
"I'll tell you everything, when we I have time, okay?" Eren had replied to Frieda.
After another two minutes of walking, the tall Yeagerist with short black hair and brown eyes had finally led the three Titan Shifters toward the throne room, where Floch Forster was currently in. Floch Forster's back turned toward them. Floch stood in place with his arms behind his back. Standing in front one of the large glass windows.
Eren's eyes narrowed a bit as he stared at Floch's backside from a few yards away.
"Who the hell is that guy?" Ymir muttered.
Drew, then walked a bit closer toward the throne and saluted toward Floch, despite Floch's back is facing him. "Commander Floch! I have great news!"
'Commander?' Frieda had thought.
"If you had not located any outsiders, spies or trespassers, then don't bother me until you do." Floch told the tall Yeagerist, drew as he had continued staring out the window. Floch had noted a skua bird outside of the castle flying across the sky.
Eren had taken a few steps forward and stepped right next to Drew, the tall Yeagerist who escorted him into the castle. "Floch."
Floch lightly gasped when he heard a familiar masculine voice. 'That voice... could it really be?' Floch questioned himself, then quickly turned his body around to see Eren Yeager in the flesh. His eyes widened, feeling surprised. "Eren?"
Eren did not respond at all as Floch stared at him. He blinked, though.
"My god... it really is you. You're alive!" Floch smiled, then ran toward Eren with joy. "It truly is a miracle! We thought that Marley had killed you but-"
"Did anything happen while I was gone?" Eren asked.
"Yes. A whole lot has happened. Since, you've disappeared, three months ago." Floch had informed Eren.
Eren's eyes had widened only a centimeter.
Frieda stared at Eren from behind, feeling concerned. After hearing that Eren had been gone for three months.
