All things are three at Hogwarts

"Luna, who is Sarah?" Allen asked.

"Sarah, can you reveal yourself to Alan?"

Luna turned to the right, and Alan noticed that a lot of hair was missing from the back of Luna's head!

In Allen's eyes, the scene in front of him looked a bit weird.

Luna was talking to the air, or in other words, Luna was talking to someone whom Allen couldn't see.

Thinking of the evil invisible man outside the mirror, Allen quietly clenched the wand in his hand.

"Hey, Alan, you don't have to be so nervous."

A high-pitched, thin voice sounded exactly like the voice Allen heard in the fog before.

A beautiful girl appeared next to Luna.

She had long, curly, light blond hair that fell down the sides of her face.

Her face was beautiful, delicate and pale, incredibly white.

"Alan, this is Sarah, Mirror Spirit."

Luna introduced in a singing voice, "Sarah not only guided you in the direction with her singing, she also saved me."

"It's nothing, Luna, your soul is still here in the end." Sarah's voice was a little sad, "The shadow must have taken over your body. Once he goes out, I'm afraid there will be no peace in the magic world."

"Luna's body?"

Allen quickly summoned Luna's body from the system's pet space, and then laid it flat on the ground.

After leaving the gray fog, the system was actually usable again.

Sarah looked at Allen with interest, then pushed Luna towards her body, and Luna returned to her body.

Luna, who was lying on the ground, opened her eyes, stood up slowly, and moved her hands and feet slightly.

"Thank you, Ellen!" Luna turned back, "Thank you, Sarah."

Alan was surprised to realize that he still owed Sarah a thank you, so he also said: "Thank you, Sarah."

The smile on Sarah's face grew wider, "I'm glad to meet you. I've been waiting for people like you for a long time!"

"In fact, if you can't break the mirror space and come to the mist space, I have no choice." Sarah said gently, with a smile on her face, but there was a strong look of sadness in her eyes.

"Without you, I'm afraid my soul would have been swallowed by the shadows." Luna stared at Sarah with her big eyes, her face serious.

Who is Shadow?

How did Luna get through the mirror space?

What does it mean for the shadow to swallow Luna's soul?

Question after question came to Allen's mind.

"The shadow is my shadow." Sarah said sadly, as if she had read through Allen's mind.

Alan and Luna looked at Sarah silently.

They knew that at this time, being a quiet listener was the best reward for Sarah.

"I am the mirror spirit belonging to Helga Hufflepuff. After Helga passed away, I was alone for a long time." Sarah fell into memories.

"Although I am extremely eager to leave this space, even if I go to death, I must survive before completing Helga's instructions." Sarah said quietly.

"But I was really lonely, so I went to the mirror space and split my shadow. I originally thought I could get a companion forever, but the shadow is completely different from me."

Sarah paused, looking incomprehensible.

Her voice was extremely sad, "Shadow doesn't want to live in this empty, silent space. She doesn't want to fulfill Helga's last wish. She wants to go to the outside world. She even wants to occupy the entire magical world. She is so ambitious!" "

"In the long years, we have gone through countless struggles. She occupied the mirror space, and I guarded this last pure land. The gray fog in the middle is the result of our constant struggle." Sarah His expression returned to calm.

"But you don't regret it." Luna hit the nail on the head.

"Yes, if it weren't for Shadow, I might have gone crazy during these long, lonely years."

Sarah had a complicated look on her face. She loved and hated this shadow.

To a certain extent, maybe she is happy to see this situation, letting the shadow accompany her to fight every day.

Allen was keenly aware that Sarah was not telling the whole truth.

For example, why is Shadow so obsessed with her?

Shadow had obviously managed to break out of Helga's mirror.

"I have what Shadow needs here. Without it, Shadow will never be able to leave Helga's secret realm."

Sarah glanced at Allen and seemed to understand what Allen was thinking.

This made Allen secretly frightened.

You know, over the years, his occlumency has been operating all the time, and it has almost become Allen's instinct.

"So what is your wish?" Allen asked the question he wanted to know most.

"My wish is to fulfill Helga's last wish, then become one with the shadow, and see the outside world."

Sarah calmly stated her wish.

"Helga's last wish?" Alan asked doubtfully.

"Yes, if you can make Shadow and me become one, I will tell you Helga's last wish."

Sarah's blue eyes stared into Alan's, her blond hair shining around her pale face.

"Okay, you can leave. You will successfully bring Shadow back, right?" Sarah asked softly.

"They don't have to come to me, I'm coming to you, my dear Sarah!"

An evil voice sounded in this space.

Allen and Luna stood back to back, carefully looking at the space around them.

"Shadow, please come back, so Helga's last wish can be fulfilled!"

Sarah took a few steps forward eagerly, her light blond hair swaying slightly.

"But, Sarah, why don't you understand? I don't want to be one with you, I am who I am. I don't want to be like you, who obviously has a treasure and can conquer the world, but just stays here in vain and wastes time!"

Shadow's voice became more and more angry, "Sarah, you are a big fool!"

"Why don't you give up the treasure Helga left behind, and I'll let the two of them stay with you forever!"

Shadow's shrill voice was particularly scary.

"Shadow, thanks to them, Helga's last wish will be fulfilled soon. Come back, okay?"

Sarah moved forward again, with a pleading look in her beautiful big eyes.

"Not good!" Shadow's shrill cry almost pierced Allen and Luna's eardrums.

Sarah was knocked to the ground by an invisible giant.

Allen suddenly cast a spell in one direction, and a colorful figure appeared in everyone's field of vision.
