Chapter 3: The Battle

Percy, Annabeth, and Grover made their way to the top floor of the Ministry of Magic, where they found Harry Potter in a heated argument with a group of Death Eaters.

"Harry!" Percy shouted.

Harry turned to face them, his wand at the ready. "Who are you?" he said.

"We're from another world," Annabeth explained. "We have a message for you."

Harry lowered his wand, and the Death Eaters stepped back, wary of the newcomers.

"What's the message?" Harry said.

Percy held up the ring. "We found this at the bottom of the sea," he said. "And we were told to seek you out."

Harry's eyes widened as he took the ring from Percy's outstretched hand. "This is the Ring of Morgath," he said. "It's one of the most powerful magical artifacts in existence."

Suddenly, the room was filled with a blinding light as a dark figure emerged from the shadows. It was Morgath himself, the dark wizard who had been searching for the ring for centuries.

"Give me the ring!" Morgath hissed,

Percy, Annabeth, Grover, and Harry stood ready, their wands and weapons drawn. Morgath's eyes gleamed as he surveyed the group, his gaze lingering on the ring in Harry's hand.

"You fools," Morgath sneered. "You think you can defeat me? I am Morgath, the most powerful wizard in the world!"

"We'll see about that," Harry said, his voice firm and steady.

With that, the battle began. Spells and weapons clashed as the group fought against Morgath and his Death Eaters. Percy used his water powers to create a shield, protecting his friends from harm. Annabeth swung her sword with precision, taking down enemy after enemy. Grover played his pipes, summoning vines and roots to ensnare the Death Eaters.

Meanwhile, Harry focused his magic on Morgath, sending powerful spells his way. But the dark wizard was no easy opponent. He was able to deflect Harry's spells and counter with his own, sending blasts of dark magic towards the group.

The battle raged on, with neither side gaining the upper hand. But then, something unexpected happened. The ring in Harry's hand began to glow with a bright white light. It pulsed with energy, sending waves of power throughout the room.

"What's happening?" Percy shouted, struggling to maintain his shield.

Harry closed his eyes and concentrated. He could feel the power of the ring flowing through him, filling him with strength and clarity. And then, he knew what he had to do.

With a mighty roar, Harry raised his wand and shouted the most powerful spell he knew. "Expecto Patronum!"

A brilliant silver stag burst forth from the tip of Harry's wand, galloping towards Morgath with blinding speed. The dark wizard tried to deflect it with his own spells, but it was too late. The Patronus collided with Morgath, sending him flying backwards.

Morgath hit the wall with a sickening thud, then crumpled to the ground, defeated. His Death Eaters fled, their morale shattered by the sight of their leader's defeat.

The group breathed a sigh of relief as the battle ended. Harry, still holding the Ring of Morgath, looked down at it with wonder.

"It's over," he said. "We did it."
