"They are late." pouted Bunny.

"That was foreseeable. You know Haruka and Michiru." said Harry.

"Regardless, we have so much to do today and we are going to meet the Weasleys in Diagon Alley… We should go without them."

"Patience is important, Bunny. Haruka would kill you, when you leave them behind." said Luna.

"Hmpf." said Bunny and stuck her tongue out at Luna.

Haruka and Michiru entered the room.

"Sorry, we're late." said Haruka.

"Whatever! Let's go." said Bunny.

Lily, Haruka, Michiru, the twins, Luna and Artemis flooed to the Leaky Cauldron. They greeted Tom, the landlord of the pub. There were only a few people in the pub. They went outside and entered the Diagon Alley.

"First, we will visit Gringotts. We will meet the Weasleys in two hours in front of Gringotts. That means we have to hurry. Let's go." said Lily.

They entered Gringotts and walked to one goblins. The goblin looked cranky. He looked at them.

"Hello, my name is Nagnok. How may I help you?" asked the goblin.

"Hello Nagnok, we want to visit several vaults. Here are the keys." said Lily.

Lily gave him the keys for vault 687 and vault Moon. Haruka gave him the keys for vault Neptune and Uranus. Nagnoks eyes widened. The Moon, Neptune and Uranus vaults were special vaults and were on the deepest level. These vaults had the highest security measures. 'If they are really descendants of the Moon, Neptune and Uranus families, they are royalty.' thought Nagnok.

"Three of the four vaults are in the highest security area, only the Head Goblin has the key for these vaults. Please wait a minute, I will fetch him for you." said Nagnok.

After a minute Nagnok returned with the Head Goblin.

"It is a honor to meet you. Please, follow me." said the Head Goblin.

They got in a cart. The Head goblin drove the cart. After half an hour, he stopped the cart. They stepped out and entered a hall with ten doors. On each door was a symbol of a planet.

The Head Goblin went to the doors with the moon symbol and inserted his key in the left of the two keyholes. Lily gave the key to Bunny. Bunny inserted the key in the right keyhole. Both turned the keys. Bunny opened the door. Behind the door was a big hall full with treasures.

"Princess, I will go and open the doors for your companions. Please call, if you need my help." said the Head Goblin and bowed.

"How do you know?"

"That you are a princess? In this area, only descendants of the origin family can open the doors. This vault belongs to the royal house of the moon. That means you are a princess."

"What would happen to a person who is not a descendant?"

"You don't want to know. It is good for you that you are a descendant. Any other questions?"

Bunny shook her head. The Head Goblin went to Haruka and Michiru to open the doors for them. Bunny, Harry, Lily and the cats entered the Moon vault. In the room were different treasures: more gold than could be count; paintings; several pieces of art; furniture; jewelry; clothes. Harry and Bunny walked through the vault with awe. They found a statue of Queen Serenity and beside the statue was a desk. On the desk were two beautiful wands. Bunny touched one of the wands. It was a wonderful silver-white wand. She didn't recognize the wood, but the wand seemed familiar.

Bunny saw two letters that were addressed to princess Serenity, but which were still sealed. She took one and opened it. It was from Godric Gryffindor.

Dear Serenity,

I saw you always as my own daughter. I couldn't come to help you in the battle against Queen Beryl. She blocked somehow the transport way. After the battle, Pluto came to us and told us about it and your deaths. She explained that you would be reborn in the far future. The months after your deaths were difficult for Albus and me. The grief was nearly unbearable, but we lived for you. We realized that you would want us to live our lives as happy as possible.

Since that faithful night 32 years have passed by. After your mother, I couldn't marry again. But I tried my best to live a good and happy life. I cared for Albus and he grew up to keen and respected man.

Albus and I could recover some of your precious things from the moon palace. We stored everything for you in this vault. I have found your wand and put it on the desk. I hope that it will serve you as well as before. I have also added some of my belongings as memories for you. Some of my books will help you certainly.

I have talked with Salazar Slytherin, Helga Hufflepuff and Rowena Ravenclaw. Hogwarts was the idea of your mother and she funded the main part of it. We decided that you are the true heiress of Hogwarts. On the desk is the contract that verifies that you. If necessary, use it to claim what belongs to you.

I wish you a long and happy life, my beloved daughter.

Sincerely

Godric Gryffindor

Bunny was weeping. While she was reading the letter, she regained some memories of Godric. She hadn't been his daughter, but he had always cared for her. He had been a good man. Harry hugged his sister. He was taller than Bunny and had read the letter over her shoulder. Harry had regained memories of Godric as well. Tears ran down his cheeks. Bunny opened the second letter. It was from Albus Gryffindor.

Beloved sister,

after your deaths, it was difficult for father and I. But we managed our lives. I married a wonderful woman and fathered three beautiful children, two sons and one girl. I wish you could have met them. I told them about you and mother. They loved the stories. I lived a good and happy life. I put a vial with some of my happiest memories on the desk. You can watch them in a pensieve. I hope you enjoy it.

Pluto told me that there is a slight chance that I will reborn with you. I hope that is the case. It would be great to see you again. I missed you so much. I put my wand on the desk. I also stored some of my most liked belongings here. I will give the key for this vault for safekeeping to Pluto.

Sincerely

Albus James Gryffindor

As before Harry and Bunny regained some memories of Albus, while they were reading the letter. Albus had been several years younger than Serenity, but they had loved each other dearly and Serenity had taken care for him. The letters touched Bunny. She was speechless and didn't move. Harry nudged her.

"We should pack the things which they have mentioned in their letter in our subspace pockets. At home, we can study them more closely." said Harry.

Both packed some of the belongings in their subspace pocket: the vial with the memories; the letters; some of the books; the wands and paintings. They went back to Lily and the door.

"Mum, should we take some of the money?" asked Bunny.

"Not necessary, we will visit our vault. Are you ready?" answered Lily.

"Yes."

"Then, let's go."

They left the vault. Haruka, Michiru and the Head Goblin were already waiting for them. They got in the cart and drove to the Potter vault. Lily entered the vault and came back after a few minutes. The Head Goblin drove the cart back to the ground level. They bid farewell and left Gringotts.

Outside they met the Weasleys and greeted them. The next few hours, they bought all necessary materials for Hogwarts. One shop on their list was Ollivander's wand shop. Bunny and Harry showed Ollivander the wands of the vault. Ollivander was zealous from the ancient wands. Bunny's wand was 11", moon oak, moon dust and Pegasus hair. Harry's wand was 13", moon holly, moon dust and phoenix feather. The wands had already chosen Bunny and Harry. After the shopping, the grownups went back to the Leaky Cauldron. The Potter twins and the Weasley twins explored the Diagon Alley together and had a lot of fun.

It was the 1st September. Bunny and Harry were walking with Hagrid to the train platform. It was common that Hagrid collected the first years from the train and led them on a different path to the castle.

On the train platform, Hagrid called for the first years to gather around him. Hagrid led the first year students along a shady path to the Black Lake. On the lake was a fleet of small boats. The students boarded the boats. The boats sailed them across the lake and stopped at a small landing stage near the base of the castle. Hagrid and the students got out of the boats and Hagrid led them to the main entrance of the castle.

McGonagall welcomed the first year students in Hogwarts at the main entrance. She led them to a small room.

"Please, wait here. I will come back, when everything is prepared for the sorting. Please keep quiet." said McGonagall.

Harry and Bunny kept quiet. They knew what to expect. Some student were nervous and started to whisper. After 20 minutes, McGonagall entered the room again.

"Please form a line and follow me." said McGonagall.

She led the students to the Great Hall. McGonagall entered the hall and the students followed her. In front of the teacher table was a chair with the sorting hat. The hat started his song.

Oh you may not think I'm pretty,
But don't judge on what you see,
I'll eat myself if you can find
A smarter hat than me.

You can keep your bowlers black,
Your top hats sleek and tall,
For I'm the Hogwarts Sorting Hat
And I can cap them all.

There's nothing hidden in your head
The Sorting Hat can't see,
So try me on and I will tell you
Where you ought to be.

You might belong in Gryffindor,
Where dwell the brave at heart,
Their daring, nerve, and chivalry
Set Gryffindors apart;

You might belong in Hufflepuff,
Where they are just and loyal,
Those patient Hufflepuffs are true
And unafraid of toil;

Or yet in wise old Ravenclaw,
if you've a ready mind,
Where those of wit and learning,
Will always find their kind;

Or perhaps in Slytherin
You'll make your real friends,
Those cunning folks use any means
To achieve their ends.

You might belong in Moon,
You come from another planet,
Combine traits of houses,
To strive the union of wizards.

Rising of house Moon,
Which was lost for centuries,
Restore Hogwarts former shine
And heal the wizard world.

So put me on! Don't be afraid!
And don't get in a flap!
You're in safe hands (though I have none)
For I'm a Thinking Cap!

The complete hall was quiet. No one was clapping. Dumbledore stood up and clapped his hands. After a few moments, others joined. 'This tricky hat, I should have known. I think we should start the sorting with the Potters. I'm curious what will happen.' thought Dumbledore. McGonagall looked expectantly at Dumbledore.

"We will start with the sorting. Potter, Serenity." said Dumbledore.

Bunny walked to the stool and put the hat on her head.

Welcome princess Serenity. I have waited centuries for your return. Godric told me that you would be reborn. You are the heiress of Hogwarts, but also from house Moon. With you it will be revived and will initiate some changes. Pluto gave me something for you. I have protected it. You need to fetch it from my body.

"MOON"

"There is no house Moon." some students shouted.

Bunny stood up and put her hand in the hat. She touched a small and round object. Suddenly, she sensed power, a big amount of power. A silver light engulfed her. Bunny could feel that her body changed. As the light vanished, she was in her princess form. Her hair was longer than before and touched the ground. On her forehead was the golden half moon visible. Two white wings were attached on her shoulder blades. The wings were outstretched. She wore a white gown with a golden border. The silver crystal was flowing in front of her. She was hovering a few feet above the ground.

The song of the hat is from the first book, but I added two verses to the song.

It is a good cliffhanger. I promise to update soon.

Relationships:

I'm still open for Harry and Hermione. But I don't think Harry and Hermione fit together. Any comments?

I hope you enjoyed it.
