Svartalheim,

"Uuuuu," Lavena was staring at the sky, with Natasha's arms wrapped around her.

Natasha had come to this realm from the connected space, directly coming to Peggy, who had been holding Lavena. Their eyes were staring at the air, battling against Malekith.

But it was less of the battle against Malekith but more against the reality stone. It almost seemed that one person was tearing the reality itself apart, breaking it like glass.

"Where is Jay?"

"Probably in another plane in the Nine Realms," Natasha whispered. Unlike others, she knew that Sephiroth and Jay were on in the same. If he was using this body to fight rather than the other one, it simply meant that strong the opponent was. There wasn't a large gap between Primo's power and Jay's power. But Sephiroth was on a whole new level.

The only problem was, Sephiroth was a side of Jay that he didn't want, the unscrupulous side that he denied. Looking at himself as Sephiroth from outside vision meant looking at the mirror, realizing what he was.

In the air,

Sephiroth slammed Malekith away, causing his body to fall to the ground, creating a crater.

Malekith moved, raising his healing body, "Mortal-"

"Shut up."

Malekith's mouth became sealed as if sewed together, making him use the reality stone to free himself. He looked up, seeing the arrogant green eyes filled with disdain for him, "You talk far too arrogantly for a coward that ran and hid. You should have stayed in your grave."

"You arrogant maggot," Malekith's face became twisted in anger as the reality around him started to change.

"WE!! The Dark Elves were glorious!!! We ruled the universe!! You dare insult the King of Dark Elves?!"

With his angered shout, the reality around him started to churn and change at a massive scale. The barren land was filled with dark forces anew; the sky-high military structures rose from the ground. Thousands of Command Spaceships, surrounded by a thousand more fighter ships, appeared in the sky.

"We were a glorious civilization! That will cover the universe in the darkness!! We the Dark Elves will rule again!!"

Below,

Peggy put her hand in front of her face, "I am going to relate to the Omega Flight! We need all the reinforcement that we can get!"

Steve tightened his fist, holding the shield, "I am going to help him till then."

Natasha kissed Lavena's head, who was looking at the fight with immense interest, "No need."

"But-"

"Just watch...his powers are much closer to what Jay and Primo used to possess. You'll understand when you see it."

"Carter!"

Peggy put her hand on her comm, "What?"

"Our systems have been hacked! There's-! There's-!"

"What?!" Peggy's expression became more urgent.

"Music!"

"What?" This time her expression turned confused.

In the air,

Purple energy started swirling around Masamune as Sephiroth looked at the enemy forces, "Then let me give it a glorious end."

Sephiroth raised Masamune, and a purple light flashed to the sky, causing clouds to appear in Svartalheim's sky, covering the last light coming from the sun. The clouds swirled, with music reverberating on the whole planet.

Malekith looked up at the sky; when the whole planet shook, the clouds were torn apart as a meteor appeared in front of their eyes. It was an immense meteor, destroying the atmosphere itself, coming down on them,  catching fire.

"Attackkkk!!! Attack!!!!!" Malekith screamed, causing the ten thousand ships to attack.

But their resistance didn't even create a scratch in the gargantuan meteor that came down on them.

"Retreat!!!! Retreat!!!" Peggy screamed, ordering all her forces to run away.

The first line of Dark Elves fighter spaceships was getting crushed like insects. The ground was burning, the dust storm rose from the ground.

Steve already had Peggy in his arms; he put his shield on his back, flying through the air, trying to gain as much distance as he could.

Natasha was holding Lavena, using the sky regalia to keep up with Steve. But it didn't matter if they crossed hundreds of miles; they couldn't seem to run the meteor's range.

"Get on the ship! We are going to warp right now!" Peggy tried to communicate with the comms, but even they were being jammed from the presence of the meteor.

Steve and Natasha jumped in the sky, entering one Quinjet before the whole fleet started warping out of the Dark Elves Planet.

Even as they got out, they marveled at the meteor that was one-third the size of the whole planet, invading it, burning it down, crushing it.

On the surface,

Sephiroth looked back at the sky, letting out a breath of relief after Natasha and Lavena were out of danger. He turned his sight back to the Dark Elves created by the reality stone, seeing them trying to fight against the meteor.

The closer the meteor got, the more it destroyed until it hit the planet, causing a blast that covered the whole surface. The explosion spread out, covering the continent, reaching further to coat the entire civilization, destroying it, before the planet's surface was wiped out, burning, melting, broken.

Sephiroth landed on the burning planet, walking forward to the place where Malekith was before. He stepped at the center of the enormous crater, cutting it into two. He pierced Masamune inside, bringing out a half-broken head, which was being healed with the red energy of the reality stone.

Even in a condition like this, he was still healing, "You are really desperate."

"Dark Elves will rise-"

"Shut up," Sephiroth pierced Masamune in Malekith's neck, hoisting his head on the sword, "I am not talking to you."

He raised his hand, which phased through Malekith's face, bringing out a red stone from inside them.

"Aethe-" Malekith spoke to the last breath, his head turned into dust, disappearing.

Sephiroth held the reality stone in front of him. This was the first time since the Convergence that he had been in close contact with an Infinite Stone. He could feel a part of his soul inside it, a longing that wanted to become one with him again. It was a longing that came from both sides.

For so long, he had been trying to guess the motives of infinity stones, changing his guesses with the change in circumstances. Now that Jay (Sephiroth) was holding on in his arm, he became confused again.

The stone seemed to desire to merge with him. And yet, they went to the being like Ultron and Dark Elves. Beings that were bound to stand against them.

Moreover, there was another danger; the stones were sentience, even if they were to become one with him. His body would become a husk, his mind would be sent in an eternal battle for control over the body. Or of his unique being, he might even take over the stones and truly become Omnipotent and Omniscient.

Sephiroth closed his eyes for a moment as if hearing the whispers of the stone when a storm arose. The energy coming from Sephiroth started fighting against the stone, trying to crush it, "All that sounds tempting, but I can just crush you and take my soul back."

Dark thunder and lightning rained down from the sky, hitting the reality stone; the space tore apart, the seemed to be getting crushed itself.

If Wanda was here, she could pass through its defenses. And break the stone, but he had to do a frontal battle.

Just when he was about to increase the intensity of the attack, a white pillar appeared in front of him, carrying lightning, "Stop!"

Sephiroth looked up, tilting his head, "Odin, what do you want?"

Odin narrowed his eyes, "I am here to stop you from destroying the reality stone."

"Give me a reason why? These stones are bound to bring trouble that no one is ready for."

"Maybe, but they might also save us from the trouble that no one is ready for. If the phenomenon that had merged the two universes is repeated again. We would need the stones again."

Sephiroth glanced towards the stone, taking back the Masamune, throwing the stone at Odin, "Don't let the stones out of the Nine Realms."

Odin caught the stone, nodding, "It will be safe in my treasury."
