Hogwarts: The Savior's Strong Cousin

One morning, Harry was having breakfast in the Great Hall when he suddenly received an urgent owl letter. The letter was written by Professor McGonagall, with only a short sentence: "Come to my office immediately, it's an emergency."

Harry's heartbeat quickened, and he stood up and walked quickly to Professor McGonagall's office. Hermione and Ron followed him, and it was obvious that they had received the same letter.

When they walked into Professor McGonagall's office, she looked very serious. She said bluntly, "Professor Snape has escaped."

Harry was stunned and asked in disbelief: "Escaped? How could he escape?"

Professor McGonagall sighed, with a hint of helplessness in her tone: "This morning I went to check Professor Snape's ward and found that he was gone. All the monitoring magic had been destroyed by him. He obviously left on purpose."

Hermione turned pale and whispered, "Is he being controlled by Cyrus?"

Professor McGonagall shook her head. "It is not clear what his motives are, but it is certain that he is in great danger."

Harry felt a complex emotion in his heart. He had always had complex feelings towards Snape, with both gratitude and doubt. But he knew that now was not the time to be emotionally entangled. He had to find Snape and find out the truth.

"We must find him," Harry said firmly, "Whatever the reason he escaped, we cannot let him fall into Cyrus' hands."

Professor McGonagall nodded, "I have already arranged for some professors and senior students to search, but we need more help."

Hermione quickly analyzed: "Professor Snape's magical attainments are extremely high. He may have used some kind of concealment magic. It is difficult to find him with ordinary search methods."

Ron agreed: "Yes, we need some special methods to track him."

Harry suddenly thought of something and turned to Professor McGonagall: "Professor, does Professor Snape usually have any special places he likes to go, or any special habits?"

Professor McGonagall thought for a moment and said, "He often goes to the depths of the Forbidden Forest to collect some special magical materials. Maybe he will go there."

Harry nodded: "Then let's go to the Forbidden Forest and see if we can find any trace of him."

The three of them quickly prepared their equipment and set out for the Forbidden Forest. The Forbidden Forest was quiet, and the air was filled with a mysterious and dangerous atmosphere. Harry, Hermione, and Ron moved forward cautiously, fearing that they would miss any clues.

After walking for about half an hour, they found some traces of trampled things and traces of magic in an open space. Hermione squatted down, examined them carefully, and whispered, "These traces are very new, they should be left by Professor Snape."

Harry felt a surge of hope and continued along the trail. Suddenly, they heard a low spell not far away. Harry quickly raised his wand and signaled Hermione and Ron to be careful.

As they quietly approached the source of the sound, they saw Professor Snape standing in front of an ancient stone formation, seemingly casting some powerful magic. Harry's heart tightened, and he quickly walked forward and shouted, "Professor! What are you doing?"

Snape turned around, with a flash of surprise and mixed emotions in his eyes, but he quickly regained his composure: "Harry, you shouldn't be here."

Harry felt a surge of anger and confusion. "Professor, why did you run away? What happened here?"

Snape was silent for a moment, and finally sighed: "I must complete this task, it is related to the safety of Hogwarts. Cyrus has not been completely defeated, he still has a backup plan."

Hermione asked anxiously, "So what should we do? We need your help."

Snape's eyes became firm, "This is what I am doing. I am trying to destroy Cyrus's last magic circle. This is the last source of his power."

Harry felt a jolt in his heart. "Professor, you shouldn't take these risks alone. We can face this together."

Snape smiled slightly, with a hint of warmth in his eyes: "Harry, you have done a good job. But there are some things I must do myself."

At this moment, a powerful dark force suddenly surged out of the stone circle and rushed straight towards Snape. Harry, Hermione and Ron immediately raised their wands to try to resist this force, but it was obviously very strong.

Snape quickly cast a protective spell to protect Harry and the others behind him. His face turned pale, but his eyes were full of determination: "You must leave here. I will complete this last task."

Harry felt a wave of weakness and guilt, but he knew that now was not the time to hesitate: "Professor, we can't leave you behind!"

Snape said firmly: "This is an order, Harry. You must protect Hogwarts. I will do my best."

Harry, Hermione and Ron were pushed away from the stone circle by the protection spell, and watched Snape face the dark power alone. They felt extremely anxious and painful in their hearts, but they also knew that Snape was using his life and strength to protect them.

Harry clenched his wand, his eyes filled with tears, but he knew that he had to obey Snape's orders. They quickly left the Forbidden Forest and returned to Hogwarts to report the situation to Professor McGonagall.

That night, Harry stood on the tower of Hogwarts, looking at the forbidden forest in the distance, his heart was filled with mixed emotions. He knew that Professor Snape's sacrifice was to protect them, but he also deeply felt that the responsibility on his shoulders was even heavier.

Harry Potter is now a teacher at Hogwarts, teaching Defense Against the Dark Arts. He and his friends, Hermione Granger, Ron Weasley and other members of the Order of the Phoenix, have been working to protect the school from the forces of darkness. However, in recent months, a series of disturbing events have begun to occur on campus.

First, Harry discovered that many magical creatures on campus had become unusually violent. The unicorns in the Forbidden Forest began to attack anyone who approached them, and the descendants of Hagrid's pet giant spider Aragog, who was originally docile, suddenly became hostile to humans. Even the house elves at Hogwarts began to behave strangely and refused to perform their daily tasks.

At the same time, magic props in the school frequently malfunctioned. During the Quidditch match, a flying broom lost control, causing injuries to several students. In class, the magic of the wand failed, and there were frequent explosions in the potion class, making it difficult for students to study. To make matters worse, even Fawkes, the phoenix in the principal's office, suddenly disappeared.
