Chapter 56: The Beginning of a Greater Threat

Grant Ward and Clint Barton were on duty in one of S.H.I.E.L.D.'s most secret and protected facilities, where the Tesseract was stored. The atmosphere in the place was one of controlled tension. Even for two seasoned agents like Ward and Barton, protecting an object as powerful and enigmatic as the Tesseract carried a heavy responsibility. The glowing cube, floating within its confinement, emitted a faint blue energy that seemed to pulse from time to time.

"I never get used to it," Clint said, observing the object from afar.

Ward, arms crossed and serious, nodded.

"I know what you mean. This is not something we were trained to deal with."

They knew that the Tesseract was not just an object of scientific interest; it was an incomparable energy source, and what S.H.I.E.L.D. What Ward actually planned to do with it was a mystery even to the field agents themselves. Ward knew that the Tesseract was an infinity stone. Dr. Erik Selvig, who oversaw the cube's studies, was immersed in his research, trying to understand what the Tesseract really was and how it could be used.

Grant and Clint were part of a team that would ensure that no threat came near the facility. Security was top notch, with automated defense systems, constant surveillance, and elite S.H.I.E.L.D. agents spread out in strategic positions.

"Do you think anything will happen?" Clint asked, in his usual relaxed tone.

Grant looked at the cube once more, feeling an uneasiness he couldn't quite identify. "I hope not. But with something like this, there's always a risk."

The calm was suddenly and devastatingly interrupted. Without any warning, a blue energy began to flow more strongly from the Tesseract, illuminating the entire room. Erik Selvig, who was only a few feet away from the cube, took a step back in shock. Alarms sounded immediately, and Grant and Clint instinctively drew their weapons, moving toward the cube to assess the situation.

"Selvig, what's going on?" Grant shouted.

"I don't know! This… shouldn't be happening!" the doctor replied, clearly terrified.

Then, from the center of the Tesseract, a beam of blue light shot out, opening a portal. Grant barely had time to process what was happening before he saw a tall, imposing figure emerge. He was dressed in shining golden armor and wielded an ornate scepter. His eyes glowed an evil green, and his presence seemed to instantly dominate the room.

It was Loki.

Grant and Clint took defensive positions, aiming their weapons directly at the newcomer.

"Don't move!" Grant shouted, as Clint readied his bow, a deadly arrow already drawn and aimed at Loki.

Loki, however, sneered, as if the two agents posed no threat whatsoever.

"Humans… so fragile and predictable," Loki muttered, his tone filled with arrogance. "You don't even know what you're dealing with."

Before Grant or Clint could act, Loki extended his scepter toward them. A beam of energy flashed, striking Clint squarely in the chest. The archer staggered for a moment, but then his eyes opened, revealing the blue glow of mind control.

"Barton!" Grant shouted, realizing what had just happened.

But before he could do anything, Clint, now under Loki's control, turned on his own allies. With impressive agility, he took down two S.H.I.E.L.D. agents with precise arrows, without hesitation.

Loki advanced, as chaos ensued in the facility. Grant realized that the situation was out of control. They were losing ground quickly. Clint was fighting his own comrades, and Loki, with his scepter, was advancing towards the Tesseract.

"Erik!" Loki called, and Dr. Selvig, now also controlled by the power of the scepter, joined the Asgardian god's side, blindly obeying his orders.

Grant, knowing he needed reinforcements, radioed.

"This is Ward! We have a breach! Loki is here, repeat, Loki is here and Barton has been compromised! We need reinforcements now!"

On the other side, Maria Hill answered, her voice serious and urgent.

"Reinforcements on the way, hold your positions!"

Ward moved quickly to protect Maria Hill, who was running towards the conflict zone. Clint, now under Loki's control, fired an arrow straight at her, but Grant, with quick reflexes, managed to pull her back before the arrow reached its target. They took cover behind a wall.

"Barton... he's with Loki." — Maria said, panting, trying to process the situation.

— Yes. He's under mind control. We need to stop them before they leave here with the Tesseract. — Grant replied, already formulating a plan in his mind.

Loki, however, was one step ahead. With Erik Selvig and Clint at his side, he used the power of his scepter to access the facility's controls. The building began to shake as a controlled explosion opened an exit in the perimeter.

"They're escaping!" Maria shouted, pointing to the vehicle that Loki, Clint, and Selvig were entering.

Grant looked around, evaluating his options. There was no way to stop them here, but they could follow the fugitives and track their movements. He pressed the radio again.

"Fury, Loki escaped with Barton and Selvig. He has the Tesseract."

Nick Fury's voice sounded gravelly.

"Understood. We're activating the Avengers Protocol. Ward, you and Hill need to return now."

Back at S.H.I.E.L.D. headquarters, the chaos continued. News of Loki's escape and the loss of the Tesseract circulated rapidly through the halls. Grant, still on high alert, met with Maria Hill and Nick Fury in the command room. Fury, with his always imposing presence, had already begun to take the necessary measures. Beside him, Phil Coulson was discussing contingency plans.

"The situation is not good, Ward," Fury said, crossing his arms as he looked at the monitor that displayed the footage of Loki escaping the facility. "We lost the Tesseract, and with it, the advantage we had over any threat that came our way." "And we have Barton and Selvig under mind control. They have Loki now," Maria added, visibly frustrated with the situation.

Fury shook his head, with an expression of someone who had already been through many crises, but this was one of the most complicated.

"That's why we activated the Avengers Protocol. We can't face something of this level alone. We need more strength, more intelligence... and a little luck." Grant heard the name of the protocol and, in his mind, he knew exactly what it meant. Earth's mightiest heroes were about to be called together for a common cause.

"We're bringing them all in," Fury said. "Stark, Banner, Romanoff, Rogers… And you, Ward, will be key. We need someone trustworthy in the field to coordinate this."

Grant nodded, knowing that his role in the events to come would be crucial. He turned to Maria, realizing how much this situation weighed on both of them. They had been the first to face Loki and had lost Clint in the process. Now, the responsibility to make it right fell to them.

For the next few hours, Grant and Maria worked alongside Fury and Coulson to prepare for the war that was to come. They knew this would be no ordinary battle. Loki was not only a physical threat, but also a psychological one. With his ability to manipulate minds and his desire to dominate Earth, he represented something they had never faced before.

As Grant prepared for the mission, he looked down at the weapon in his hand, knowing that this time, it would not just be a matter of strength. They would need strategy, intelligence, and most of all, trust in each other. Maria approached him as he checked his equipment.

"We're going to get Clint back," she said, her voice firm.

"Yes," Grant replied, determined. "We're going to get him back… and stop Loki."

War was about to begin, and Grant Ward knew the fate of Earth was at stake.
