Nebula Near Nova Empire,

The space in front of the Nebula warped, creating a black sphere before a Golden Celestial with four golden-colored eyes appeared. A black triangular ship parked on its shoulder as it entered the Nebula.

Domo,

"Ok, that was fast," Lavena thought she should sleep, but they were already here.

"We are being carried by a Celestial, isn't that obvious," Gilgamesh said with confidence, whispering to Thena the next second, "That was too fast."

Druig looked at the virtual reflection of the Nebula, "Again, why are we here?"

"Because Mom told us that this might be the place where our Grandfather might be," Illyana shrugged, "We just had to check it out. Maybe he could tell us more about the Celestials?"

Makkari appeared before her, asking with hand signs, "What do you want to know?"

Galacta blinked, "You can talk now...you remember?"

"For now...I am more comfortable this way," Makkari explained.

"Oye, over there," Druig pointed towards the screen, making others look at a seemingly gigantic structure that made a Celestial the size of Earth look tiny.

"This...I gotta see," Galacta transmuted the Domu, turning the wall in thick vacuum glass, "Oh wow."

Lavena stepped forward, placing her hand on the glass, seeing a structure made in the shape of a heart, a glass heart, with thousands of worlds, the form of the planet inside it. And at the center was a planet-sized empty throne. If she had to compare of size, then it was the size of a solar system.

Her eyes darted around the glass planet, of different sizes, with varied environments on the inside, "It's the Heart."

"It's kinda obvious," Druig narrowed his eyes, "Unless you mean something else."

"When my Dad lost his powers, he created the Heart, a weapon that allowed him to create, grant, or even take supernatural powers. But since the Heart wasn't in his control and had sentience, it granted powers to Grandfather and Uncle, and many others. Dad disappeared, and Uncle...well, it seems that Heart was left with Grandfather," Lavena breathed in, with a scarlet glow in her eyes.

Just as she was about to teleport, Billy put his hand on her shoulder, "Take us too."

"Yes-"

She just said that when they were forcefully teleported, Tiamut included, they could see again they were in a forest, standing in front of a wooden house.

"Uwa!!"

Lavena had barely taken a step forward when a surprised scream brought her attention, making her look back only to surprise, "Tiamut!"

Tiamut was standing between them, human-sized. Tiamut raised his hand, waving at others, pointing towards the house.

"He's inside?" Lavena stepped forward, but Illyana ran up, "Me first!"

"No, wait!" Lavena puffed her cheek, rushing right after, opening the door with Illyana, looking inside. Their eyes fell on the man with blonde hair, orange eyes sitting on the floor, leaning against the sofa. The smile had barely reached their lips when their face fell, seeing the young girl, blonde hair, think red lips, lying on the couch, reading a magazine.

""Oh, Fuck you!!!""

Lavena and Illyana slammed the door shut, turning around to look at their crew, "We are leaving."

"Umm...ok?" Gilgamesh blinked, "Did something happen?"

Inside,

Primo paused the Netflix, looking back at Ruby, "See. I told you they won't take well to your presence."

"Mmhm, I know," Ruby put a strawberry between her lips, "If they bothered to ask me if I knew where you were. I would have told them."

Primo chuckled, turning his eyes towards the door, seeing Lavena and Illyana begrudgingly walk in, followed by others, "Hey, sweethearts. I have been waiting for you."

He sat upon the sofa, shifting Ruby; when their surroundings changed, the forest, the house, and everything else disappeared. Everyone stood in a roofless broken hall with a throne in front and center.

Lavena blinked, seeing Primo sit on the throne and Ruby sitting on the armrest, "Welcome."

Lavena didn't even bother to look at him; she fixed her gaze on Ruby, "You knew?"

"Yes, genius."

"You could have told us!" 

Ruby watched her nails, "You could have asked."

"Umm...Uggggggghhhhhh!!!" Lavena turned around in frustration, trying to regain her breath.

Druig rolled his eyes, walking forward to the bow, "It's an honor to meet the Great Primo Prometheus. I am an admirer of your work."

Primo warmly smiled back at him, "And I am of yours. It takes much will and character to not use powers like yours to bend others to your will."

"I find it impressive."

"You know about me," Druig was surprised.

"I know about everyone," Primo moved his eyes towards Thena, Gilgamesh, Makkari, Galacta, Tiamut, "Congratulations on being born."

Tiamut spoke for the first time, "What is this place?"

"You can speak?" Lavena looked back and asked, but the Celestial ignored her as he watched the worlds in the distance.

"It's not a place; it's a...person," Primo replied, "But it's sleeping just like you."

Tiamut's four golden eyes looked around, nodding before he pushed Lavena and Illyana forward, encouraging them to talk. When they wouldn't, Billy walked past them, leisurely talking, "Grandpa, are you trapped here?"

"Oh, finally, someone smart," Ruby scanned Billy, scanning him from top to bottom.

Primo pressed his lips, smiling, "Jay created the Heart to act as his soul, but it didn't just act as his soul, and it served as mine as well. Whatever Jay did after leaving this Universe, he doesn't need the Heart anymore. But the enemies that I predicted would come were far too strong, so I used the energy stored from the Infinity Stones and asked Heart to evolve."

He circled his finger, "This is the Evolution. If I leave its territory, then I'll become unstable, so yes, I am trapped."

"And she can come here because?" Billy curiously asked.

"Because I bored to try and find him."

"Others tried! Everyone tried!"

"Not...everyone exactly," Primo watched her, "Those who tried to search this Nebula, in particular, didn't have a connection with the Heart, so they never saw it."

"So they never found it," Billy nodded.

"We found it because of Lord Tiamut and his powers?" Druig respectfully looked towards Tiamut, turning his gaze away. Even now, for Eternals, Celestial like Tiamut wasn't less than a God.

"Yes, Tiamut the Communicator," Primo crossed his legs, "He formed a connection that allowed you to see the Heart and hence reach here."

"So I was right...that event was the key," Lavena breathed in relief, "I am glad. So...how do we free you from here?"

"The event was the key," Primo shook his head, "Sweety, you were the key. You are the key, and him."

"Lord Tiamut?" Gilgamesh looked towards Tiamut, who quietly stood there.

Ruby groaned, "Ugh, you are being so long-winded. I'll make it short...everyone that Heart grants its powers to evolves in specific ways; their weakness isn't that much of weakness, making them a bit more all-round and strong. In return, it also allows the Owner of the Heart to use ten percent of their powers. Your ability, rather physiology that allows you to produce energy with every heartbeat, and Celestial Tiamut's ability to teleport his planetary-sized body. Those two abilities are the key to moving something this size."

"Oh, but...I can't...just ask something like that from Tiamut," Lavena looked down, struggling.

"You are not," Primo looked towards Tiamut, "I am."

Tiamut stepped in front of the others, looking into Prmo's eyes, forming a connection. The two shifted to a mental realm, watching everyone who froze, "I have watched you for years."

"I know...you were half awake," Primo leaned back, "My energy was enough to wake you up...so I had to distribute it through the Universe. Soon Celestial's will be born at a large scale."

Tiamut stepped closer to him, understanding something, "Because I have been watching you for so long, I wish to know. What is your endgame?"

Primo chuckled, "I don't have any particular endgame...but there is something I find interesting."

"Did you know all magic originates from the Fifth Multiverse?"

"Where did you hear about that?"

Primo smiled, "Well, that's what I heard, and that's all I'll say. Try using your imagination a little."

"Hmp," Tiamut smiled, "I see...I'll try and figure it out."

He raised his hand, "If I can be of help, then I don't mind."

Primo stood up from the throne, "You know your decision; if you died, then it would be nothing. Now that you are alive...it's basically going against Arishem."

"I understand."

"This might turn into a Civil War between New and Old Celestials."

"I understand that too."

"Do you really plan on letting Lavena lead?"

"She is the only one who can."

Primo sighed, "Oh well, this was bound to happen sooner or later. Take care of her."

"I will try my best."

"Thank you."
