It was 1 year after the final battle at Hogwarts.

. . .

It was 1-year reunion at Hogwarts.

In the middle of talks and recollections the ghostly silver phoenix flew into the Great Hall and in Dumbledore's voice invited six friends to Headmaster office - to share celebration with the portraits of the former headmasters.

Of course, normally, portraits cannot cast Expecto Patronum (or, for that matter, any other spells), but, naturally, as Harry could have explained to his friends, being "Dumbledore's portrait" has its advantages.

So, Harry, Ron, Hermione, Neville, Ginny and Luna went there. As Neville, Ginny and Luna never before saw this office - they looked around and marveled at various trinkets and portraits.

Although, it seemed, Luna tried to keep her back to the portraits, which was not really possible as they (the portraits) hung on all walls. Finally a portrait of ancient wizard with blue sideburns noticed her: "O, Miss Grant, nice to see you! Is everything well?"

Ron grinned and loudly whispered: "Barmy that one, isn't it?"

But Luna kept unusually quiet for a while and then said in somewhat guilty voice: "No, this portrait is as sane as you and I. Apparently it's the sign that the time for the truth has come."

I was so much unlike Luna they knew that everybody stopped talking and looked at her.

She continued: "My real name is Frasie Grant."

Then she sighed, smiled and calmly added "And I am 240 years old."

. . .

Hermione wrinkled her forehead: "Oh, why it sounds familiar?"

Then she sharply inhaled: "Running on waves?"

"Yes, that's me." answered Luna "And thank you, it's nice to know that some people still read that Russian muggle writer. He was a good friend. Hermione, you may, if you wish, tell everybody how it's described in that book and I will tell the rest."

Hermione promptly began: "So, as the story goes, a long ago some ship sailed in the South Seas and among the passengers there was a young girl Frasie Grant. When the ship was passing by some tropical island, Frasie longingly exclaimed: 'Oh, it's so beautiful! Can't we please stop there?' And the captain answered that there are reefs and anyway they have no time for that. Then one of ship officers in course of making a compliment jokingly suggested:

'Miss Grant, you are so light that you should be able to run to that island on the water without making your feet wet.'
But Frasie did not take it as a joke, she bit her lip and thought a little and said: 'Can I, really?' And she jumped over the handrails, landed on the water and was just standing there for a moment. And then she said 'Something strange is happening; I just can't go back. Farewell, everybody.'

And so, from wave to wave, jumping over and over, Frasie Grant ran to that island.

And since then she appears time by time to sailors, lost in the sea, and help them, like telling them which course to take.

Well, Frasie, did I tell it the right way?"

Luna/Frasie said: "Please call me Luna, I'm used to it now. And yes, that's how it happened, mostly. (1)

Well it's not much to add; the island became my home. And I go to help people; and not only sailors. And sometimes I do feel lonely.

One day I saw young Luna and her mother die in that experiment. I felt so sorry for them and for daddy ... he did become like real father for me; I just acted on impulse. I took the place of Luna and lived with him since then."

After silent pause, Neville asked: "Does he understand that you are not actually his daughter?"

Luna answered slowly: "Yes and no. He is one of such people who can at the same time realize something and not realize."

Ron grimaced and retorted: "That's mental." while his bookworm girlfriend automatically commented: "Doublethink".

But Neville thoughtfully said: "I kinda can see what you mean ... and, Luna, I think I understand now why you always avoided, well, you know ..."

Luna smiled sadly and said: "Neville, I'm so sorry, and I do care about you, but …"

Neville interrupted her: "Luna, wait; no privacy here. Let's take a walk to the lake, OK?"

Reviews, please!

(1) Hermione doesn't remember the tale from the book exactly; and in the book it's told by a sailor, who may have embellished/changed something. And Luna, after more than two hundred years, isn't sure about all the exact details either. So, I did not do the exact translation; only two sentences – the italicized ones – are exact (to the best of mine and Google Translate's abilities).
