*Stark Tower, Days After the Battle*
The quiet hum of machinery filled the lab as Tony Stark sat at his workstation, staring at holographic displays filled with readings from the recent battle. The multiverse had been saved, but the data didn't lie—something was still wrong. The energy fluctuations, though diminished, hadn't ceased entirely. It was as if the balance they had restored was holding together by a thread.
Reed Richards entered the lab, looking equally tired. "You still working on that?" he asked, stepping up beside Tony and glancing at the projections.
"Yeah," Tony replied, rubbing his temples. "I thought we'd fixed everything, but these readings... they're not right. We closed the rift, stopped the collapse, but there's something we missed. I can't figure out what."
Reed frowned, examining the data. "It's possible the spell wasn't enough to fully seal the breach. The multiverse is vast, and the forces we dealt with were ancient and powerful. There could still be lingering effects."
Tony leaned back in his chair. "Lingering effects? Reed, we're talking about the fabric of reality here. If something's still out there—" He paused, his thoughts racing. "—we might be looking at another collapse, maybe even worse than the first."
Reed gave him a hard look. "If that's the case, we need to act quickly. But we can't rush in without understanding the scope of the problem. We'll need more data. And maybe... more help."
Tony nodded, his mind already turning to the possibilities. "I hate to say it, but we might need to call in more than just the usual suspects. This goes beyond the Avengers, the X-Men, the Fantastic Four. We're going to need cosmic-level backup."

*The Sanctum Sanctorum*
Elsewhere, Doctor Strange sat in his meditative chamber, the soft glow of mystical energy illuminating the room. His mind drifted through the echoes of the battle, trying to understand the forces at play. The entity they had faced—the being that had nearly torn the multiverse apart—was gone, but the residual traces of its power still lingered.
A sudden jolt of energy rippled through his senses, pulling Strange from his meditation. He opened his eyes to see the Orb of Agamotto glowing faintly. Something was calling to him—a presence, faint but growing stronger.
Strange stood and approached the orb, his brow furrowed in concentration. As he peered into its depths, a vision began to take shape—an image of the dark figure they had fought, but this time, it was fractured, splintered across different realities.
*"What are you?"* Strange whispered, reaching out with his mystical senses to probe the vision. The figure didn't respond, but the echoes of its power reverberated through the multiverse like ripples in a pond. It wasn't gone—it had merely dispersed, waiting for the right moment to reform.
Strange clenched his fists. *"So it's not over."*
He turned away from the orb, his mind racing. They had only delayed the inevitable. The dark force was still out there, gathering strength. If it returned, they would need to be ready.

*Xavier's School for Gifted Youngsters*
In the serene halls of the X-Mansion, Professor Charles Xavier sat in his study, watching over his students as they went about their daily routines. Yet his mind wasn't at ease. He had felt the disturbance in the multiverse, even from here. The energies that had been unleashed were unlike anything he had encountered before, and though the immediate threat had been quelled, the psychic ripples it left behind were troubling.
Jean Grey entered the room, her face calm but her mind burning with the intensity of the Phoenix Force. "You felt it too, didn't you?" she asked, her voice quiet.
Xavier nodded. "I did. And I fear that this is far from over."
Jean took a seat across from him, her fiery eyes locking onto his. "There's something I need to tell you, Charles. When we faced that entity, I could sense it was more than just a being of destruction. It was... searching. Looking for something. Or someone."
Xavier leaned forward. "What do you mean?"
Jean hesitated for a moment, gathering her thoughts. "I think it was trying to merge with the Phoenix Force. It recognized the power within me and saw it as a key—either to fully stabilize the multiverse or to dominate it completely."
Xavier's expression darkened. "If that's true, then we must tread carefully. The Phoenix is a force of both creation and destruction. If that entity were to merge with it, the consequences could be catastrophic."
Jean nodded. "We need to find a way to contain it before it regains its full strength. Otherwise, it might come after me again."

*The Cosmic Realm*
Far beyond Earth, in the vast reaches of space, the cosmic entities that governed the multiverse convened. The Living Tribunal, Eternity, Infinity, and other powerful beings gathered in a swirling nebula of energy. They had watched the events on Earth unfold, but they knew that the danger was not yet over.
*"The balance has been restored, but only temporarily,"* Eternity said, its voice echoing across the stars. *"The force that caused the rifts is not defeated. It has simply been scattered."*
The Living Tribunal's many faces turned to regard the others. *"The mortals have done well, but they are not equipped to handle what comes next. We must intervene."*
Infinity, her form shimmering like the endless expanse of space, spoke next. **"Intervention could destabilize the multiverse further. We must tread carefully."**
**"Agreed,"** said Eternity. *"But we cannot sit idle. The force that threatens the multiverse is beyond their comprehension. It is a being of pure entropy, a remnant of the First Firmament."*
The Tribunal's faces shifted, reflecting deep thought. *"Then we must prepare them. The mortals will need to face this threat themselves, but we can guide them."*

*Stark Tower, New York*
Back on Earth, Tony, Reed, Strange, and the others gathered once more, this time with a plan forming. They knew the battle wasn't over, but they were determined to be ready for whatever came next.
"We need to reach out to the cosmic entities," Strange said, pacing. "The Living Tribunal, Eternity, beings who govern the very fabric of reality. They've been watching. It's time we ask for their help."
"Think they'll just hand us the answers?" Logan grumbled, leaning against a wall.
Strange shook his head. "No. But they might give us what we need to finish this once and for all."
Tony sighed. "We've fought gods, traveled through time, and battled across dimensions. What's one more trip into the unknown?"
Reed adjusted his equipment. "Let's just hope we don't have to fight another cosmic entity. I'm not sure how many more realities can handle that."
As they made their preparations, the weight of the task ahead loomed large. They had fought through impossible odds before, but this time, the stakes were even higher. The multiverse was on the line—and if they failed, there wouldn't be anything left to save.
