Thank you for the story

Lily was about to answer when Aberforth rose from his chair. Few people had recognized him as the former bartender of the Hog's Head Tavern as he looked as if he were in his late twenties. "Let me answer this, Lily. You can come to the Realm or stay in this world, Mr Malfoy, we do not force anyone to pass the threshold but know that your own father is its guardian as every member of the Malfoy's lineage for centuries. He should have taught you this, at the very least. Why do you think Voldemort wanted you both as his followers, as his 1st inner circle of Death Eaters? You aren't half as evil or smart as you think you are."

Harry stood up, his wand ready to shut up Draco and defend his mother but Ginny put an appeasing hand on him and he stopped his curse before Draco even noticed it. "Let him speak" she whispered in her husband ear "I want to know what he has to say".

Draco: "You-know-Who was too looking for immortality and the promise of the very source of all Magic so tell me, why do you want wizards to go there if not for the very same reasons or maybe for something more sinister?!"

A wizard who had just joined the crowd, asked Lily Potter. "I should abandon all that I have built here to follow you Merlin knows where to be locked in some sort of ghetto, waiting to be slaughtered like some muggle in ww2? And to gain what? Immortality? Ha! Your immortality doesn't weigh much if you vanish into thin air!"

The wind pulled back his hoodie, revealing pale  blond hair but Potter had already recognized him: "Draco!".

Draco: "I've been force fed the same idiocies decades ago, I'm no longer a gullible teen. What's telling me you are who you pretend to be? "

Several hands were raised and Neville could ask his question: "Is it safe to move to that realm while we know so little about it?" He had been seated beside Luna and suddenly felt the urge to protect her.
Lily: "It is true that we've recently had motives for concern... after the disappearance of several persons who insisted they wanted to explore beyond the land that we knew was safe. However, if you remain in the places we've assigned to you, we'd do our best to safeguard you and your family. The muggle world is going to its doom, no place is 100% safe now, the choice is yours when you still have a choice."

The little town of Godric's Hollow had never seen such a large gathering of wizards and witches since they celebrated Voldemort's demise, years ago. The willow had been dressed with tables and families were seated with all sorts of food and drinks. Harry's mother, Lily had been seen, her arm locked under the potions master's arm walking the narrow streets until late but today, Snape was not there, James was. Remus, Tonks with their adult son, Teddy; Harry Potter, Ginny and their kids; Aberforth and his sister and Neville who couldn't leave Luna now that they'd met again.

Lily: "We have gathered here to try to answer some of your questions about the Lost Realm now that the time is near to decide whether we are to live there or stay among the muggles."

Neville had always adored Luna's eccentric personality, but to hear her discuss her husband's death with such indifference stroke him bad.
Luna: "He's not the only one you know and professor Snape had warned everyone not to go there without him, he wouldn't listen. His grand-father's suitcase disappeared and he had stored a couple of every magical creatures he could gather in such short time. Now I feel oblige to go as well. For the animals."
Neville thought she could mention her husband before the magical creatures but he was too worried about Luna right now and the Lost Realm felt a great deal less appealing.

Neville to Luna: "Help? You know you can always count on me, even if magical creatures have never been my field of expertise, but, Luna, I thought your husband would help; after all, his grand-dad was famous for this and he chose the same career, no?
Luna: he went to the Lost Realm, one of the first ever to cross the threshold, he said he needed to see the marvelous animals before everyone.
Neville: and?
Luna: He hadn't been allowed by Snape. He died. Disappeared. Vanished. I do not know, really. He had been warned"

Neville nodded, his eyes shining with enthusiasm. "I shall teach a new generation of wizards, unless I'd be recruited to join one of the teams due to explore... Wait, I was not supposed to talk about this."
Luna laughed and innocently added: "to explore the great space, at the other end of the wormhole where the other races have already pursued the quest for survival? Don't look at me like this Neville, I've been recruited too. I am working with Hagrid to preserve the magical creatures from this world and we don't have much time until doors close again between the Earth and the lost Realm. That's why I'm here today, I need help."

In the professors' common room at Hogwarts castle, several professors were packing and Luna Lovegood had found Neville, storing papers in a cardboard box.
Luna: Harry told me that you were considering leaving Hogwarts? You're going to the lost realm with your parents then?
Neville, who hadn't seen her coming, jumped and spilled his tea all over the table.
Neville: Oh Luna.  Yes, yes and no. I... I've been approached by Aberforth to gather all sorts of plants, seeds, to provision the Realm with everything they might need, after all, the population there shall grow and people shall need to eat, to heal, to admire its beauty and to do magic too. Another Hogwarts is being built there for the instruction of a new generation of wizards and little folk too.
Luna: so you're telling me that you'll resume your post as professor there?
