Introduction: The title for this one comes from Ode, an amazing poem by Arthur O'Shaughnessy that was published in 1873. I took the title from the first of the seven stanzas:

We are the music makers,

And we are the dreamers of dreams,

Wandering by lone sea-breakers,

And sitting by desolate streams; -

World-losers and world-forsakers,

On whom the pale moon gleams:

Yet we are the movers and shakers

Of the world for ever, it seems.

When I was looking for a title for this fic that hadn't been used or done to death for a Harry Potter fic or HP crossover, I thought of my favorite poem and how the idea of losing and forsaking a world fit this story perfectly with the trope I used to make the crossover as well as the imagery of the stanza: desolate streams, lone sea-breakers, but still alive and kicking despite it all.

If you have a minute, go look up and read the poem in it's entirety, it's seven stanzas though most people think it's only three. Go on, go. I'll wait.

Now for the things you need to know before reading this story:

I've altered at couple of ages to make the main pairing work. Also, this story is both SLASH & MPREG.

There will be some het elements as well but there are at least two slash couples and mpreg things going on. Most of the male pregnancy stuff happens in between the intro of the HP characters to the Walking Dead world and the actual start of the Walking Dead so it will mostly be "off screen" without vivid imagery of a male giving birth. Just referenced. Also with pregnancy comes children so there will be a couple OC's that are children as well as a couple of OC's who help out around Harry's place before the world goes to hell. They won't be major characters but they'll be in the background of things.

We start in a slightly AU Order of the Phoenix just before the Battle of the Ministry. Changes to the HP storyline as well as the Walking Dead storyline will be addressed as they happen. The only thing you need to know to start with is that, again, I'm changing a couple ages to keep the main pairing plausible.

On Whom the Pale Moon Gleams

A Harry Potter/Walking Dead Crossover

By

Sif Shadowheart

Prologue

"Harry Potter you listen to me this instant!"

Maybe it was over a dozen years of having to obey Petunia immediately or having Minerva McGonagall for his Head of House or being friends with Hermione Granger…sort of. But whatever caused it, Harry knew instinctively that when an individual of the female gender got that tone in her voice, he damn well better stop, shut up, and pay attention. And that was exactly what he did as he froze on the way to gathering the Thestrals from the Forbidden Forest and faced his occasionally-out-of-it friend Luna Lovegood.

Hermione and Ron had disappeared to do Merlin-knew-what before joining him, Luna, and Neville at the edge of the Forest to leave for the Ministry and to rescue Sirius. Likely send a message to Dumbledore. Harry had figured out a long time ago that they were his friends out of a desire to keep payments from the old bastard rolling in than any sense of shared adventure or actual friendship.

Neville, growing up with his Gran, froze as well, being equally as well-trained as Harry regarding female tones.

Harry and Neville hit it off after the former apologized to the latter after he got out of the hospital wing in First Year. He'd never thought Hermione would hex him like that, and it was a miracle the shy boy hadn't been seriously injured when he collapsed to the floor. So he'd done what Hermione should have: sucked it up and made it right.

Letters from Nev were the only few that slipped past Dobby that first summer, the Longbottoms using large eagles for their correspondence for centuries after they'd lost a rare heirloom due to owl-tampering in the Middle Ages. Not even a barmy house elf was going to mess about with a creature large enough to snatch it up in its talons and have it for dinner. Even at eleven, both boys knew that for some reason the Headmaster wanted Harry secluded using his "two best friends" and kept their friendship quiet until Fourth Year when everyone abandoning Harry gave them their chance to go public with it.

Second Year had brought Luna into their secret fold, Harry having found her wandering around in search of her shoes during one of his nightly wanderings under his Cloak.

With both Neville and Harry having been bullied most of their lives in one way or another, they swiftly set to trying to help the blonde who seemed to be focused on otherworldly things more often than not.

That first year of their hidden trio neither boy had known quite what to make of her until the flyers for electives came out when Harry wondered aloud if maybe Luna was some sort of Seer after reading up on Divination. Time and testing her coded warnings made them certain she had some sort of knowing if nothing else, both boys deciding to study Divination to see if there might be some way they can help her focus a little more on the world around her…if only to protect her better from those who might prey on her. After all, if it took a pair of twelve-year old's less than a year to figure her out, she really wasn't all that safe even if her code was impossible to break without knowing her the way they did and do.

It worked…sort of.

They ended up probably being the only thirteen-year-old boys with links to two verifiable Seers…even if one used a complex code and the other had only made two true prophecies in her lifetime.

Which was interesting in itself.

Professor Trelawney was a Delphic-Oracle type Seer, highly reliable with visions she herself never remembered. But she was limited in the extreme from what the three of them discovered. The sherry-addicted woman seemed to only "tune-in" to cataclysmic-potential events effecting the British Wizarding World. Case-in-point: Voldemort and how he could rise or fall.

Luna on the other hand was a Delphic-Oracle lineage Seer…which was as different from Sybil Trelawney as chalk and cheese. Her mother was Pandora Delphi of Athens before she met and married a writer and amateur cryptozoologist from Wizarding England, aka Luna's batty Father. When Luna Saw it could be something from two centuries in the future or two decades in the past that happened or would happen next door or in sub-Saharan Africa. She rarely shared the things she saw with Neville and Harry, taking after her mother who had trained her before her death and chronicling her visions using a special parchment and quill that would only reveal what was needed when it was needed and to the right person.

Fortunately, Delphic-lineage Seers were always female and would only ever gain active power when they became the oldest-living female of their lineage.

Unfortunately for Luna, her mother was the last of their line.

And her mother died in a spell-accident when she was nine.

Their best friend had been Seeing the best and worst of humanity when all she should have been worried about was learning to fly or ride a bike.

Her mother Pandora knew that something was going to happen that would take her from her daughter at a young age – but never when or what the cause would be – so she had done what she could to prepare her only child for the future Fate had written for her.

And though Harry never knew it, Pandora had prepared Luna for something else she Saw. Something involving Luna's first true friend, a boy with green eyes and a lightening scar.

This was the subject that Luna needed to talk to Harry about before they left for London, though Harry had no idea just how epically his future was about to diverge from its original path.

If he had, who knows whether he would have done as he was doing at this very moment: stopping, turning, and giving his petite blonde friend his undivided attention.

"What is it, Luna?" He asked patiently, knowing that it might take her a minute to share whatever it is she Saw.

Or at least, he thought that was what was going on, sometimes with Luna it was very hard to tell, even for him and Neville.

"Take this." The Ravenclaw demanded, shoving a necklace at him. "I don't know what's going to happen or why you need it…but you do."

Harry gently took the heavy piece from her dainty hands, studying it for a moment before shrugging and fastening it securely around his neck. If it was anyone else, he would've balked, especially after seeing the design etched into several of the heavy links. When the latch clicked into place, he felt a warmth pulse once from the old piece of heavy men's jewelry, making him arch a brow at his friend.

"It's enchanted." Luna supplied, eyes dazed as she tried to relay what she both already knew and what she Saw about the piece around her friend's neck. "My mother gave me a box before she died. In it was several enchanted items and a letter with instructions on who to give them to and when. This was for you 'before your green-eyed friend flies away to rescue a Grim.'" She refocused on her friend's worried gaze. "I know it's necessary and you'll need it: it was made so no one else can take it from you and you'll never lose it." She bit her lip helplessly as the Thestrals appeared around them and hearing the approach of Granger and the two Weasleys, Ron having gotten his sister for some reason. "That's all I know Harry."

"Thank you, Luna." He told her sincerely, reaching out and giving her a sideways hug. "Really."

"You're my friend, Harry." She answered back, eyeing where the now-hidden necklace lightly bulged against his school shirt. "I want you to be safe and happy…and now I know you will…whatever happens next."

"Sirius!" Harry screamed as he raced for the Veil, Remus right behind him as the Lord of the Most Ancient and Noble House of Black fell backwards after being hit by a vicious Stunner cast by none other than Bellatrix LeStrange.

Harry had no idea how it had all come to this but he knew exactly where to lay the blame: Dumbledore and Voldemort with their endless games. Both were equally as bad as the other as far as Harry was concerned, both using others as little more than expendable game pieces in their never-ending game for control of Magical Britain. If it was up to him he'd leave them all out to dry, Prophecy bedamned.

But it wasn't up to Harry.

Not yet anyway.

So long as Dumbledore had the safety of Sirius to hold over him, Harry would never be able to take a step without someone guiding him and making all his decisions. Luna had been very certain about that when she tried to take a peek at Harry's future to reassure him. As long as Sirius was a virtual prisoner and/or Dumbledore lived there was no chance at freedom for Harry.

Those were the conditions that bound him: either Dumbledore had to die or Sirius had to be freed.

Rather than ignoring him or running away or obeying Dumbledore or a thousand other choices that would have made Sirius and Remus little more than occasional visitors in Harry's life, they had nodded their heads respectfully when the old goat told them they were too dangerous to be around Harry or that Harry had to stay with his relatives, for his own safety of course, and then promptly fucked off to do as they pleased once the goat fucker was appeased with their "obedience."

In reality, Messrs. Padfoot and Moony had set up shop, figuratively speaking, just outside of the ward-zone Albus had set up around Number 4 Privet Drive.

Sirius had already proved that his Grim form could come and go from the wards as he pleased, the Headmaster having no real way to prevent animals from the vicinity of the Dursley residence.

And while the wards did a great deal to keep magical people out of the ward-zone it did little to keep Harry in, which was why this past summer the old man had had no choice but to station watchers around the residence, lest Harry wander too far from the "protection" of the wards.

Like he had been doing all the summer before, going off once his truncated (Sirius made one hell of a deterrent) list of chores was complete.

It didn't matter if he missed every meal with the Dursleys when Harry could – and did – easily walk the two miles to the cottage-like home of the last living Marauders, and no, Wormtail didn't count.

A summer filled with loving care and attention from his godfathers, Sirius being much saner than before thanks to regular visits with his cousin Andromeda's husband Ted who was a Mind Healer and Andy herself a Healer, regular meals, and tutelage under the loving-but-firm eyes of Professor Lupin made all the difference.

Harry knew what a family was now. He had one of his own. A real one not the whatever-the-fuckery was going on with the dysfunctional Dursleys.

Okay, yes, Padfoot and Moony weren't exactly what people thought of when they thought stable-family-environment…but they were Harry's and they loved him and each other and that was all that mattered to the teen.

So, Harry's personal freedom was predicated on Sirius's freedom…and Harry was at peace with that.

His godfathers loved him, fed him, taught him, trained him, and did everything they could to fill the massive gaps in both his magical and mundane educations. Especially once they found out that the Headmaster had hidden the Potter Lordship from him. Harry'd actually thought his school vault was all there was to the Potter wealth.

That more than anything enraged the two of them.

Dumbledore could have passed off the abuse as Harry not telling or the Headmaster otherwise not knowing. He could have said that Harry didn't show any interest in extra tuition. Or that he was just too young to learn certain necessary skills. All of that would have pissed them off but he probably would've gotten away with it.

But it was anathema, an utter taboo, to hide the heritage of a magical child.

Especially when that heritage was that of a long, long and proud magical history and came with wealth and stature along with it.

Where originally they were going to let him have the school-year off from their extra studies and have him focus on his school work, Sirius and Remus kept in touch with him through both their linked-mirrors and a set of linked-journals that they had made for him. At that point they had over a dozen years' worth of training to catch up on…sticking to summers only wasn't going to cut it even with a student as bright as Harry, who had flourished under their care and focused attention away from the Dursleys and the pressures of being the perfect "Golden Gryffindor" at Hogwarts. Remus caught him up on mundane and magical education while Sirius focused on traditional "pureblood" raising that Harry had missed, things like etiquette and protocol as well as martial training, dueling, and other so-called "Lordly" necessities.

Once Harry had survived his Fourth Year and returned to Privet Drive, it was much harder to teach him, Harry having to use his personal Cloak to slip out to the cottage or Sirius having to wait until one of the more unobservant watchers was on post to teach him. The only time it was ever "easy" was when Remus was stationed at Number 4, but they would still have to be careful lest the Dursleys rat them out to the Headmaster or they be caught in the act by Remus's replacement guard. Still, they made it work and the training and teaching continued.

One result of which was Harry being a lot less scrawny than he used to be though he was still smaller and shorter than others his age.

Something which infuriated his godfathers to no end but that they knew had to wait until he was sixteen to fix. Most wizards gained a lot of height and bulk between sixteen and seventeen in preparation for their magical inheritance, making it the prime time to correct his malnutrition and growth issues without making it look as if someone had interfered in the Headmaster's "plan". Correcting his eyesight would have to wait until then as well, except with eyes it was more to let them stabilize, else they risked additional deterioration afterwards and Harry having to go through a painful potion and spell regimen two or more times to continually fix and refix his sight.

They might not be a "normal" family but they were Harry's family…and that was all that mattered to him.

So to see Sirius falling back into a Veil that felt cold and warm, light but oh-so-dark, that whispered and called Harry's name…it was the worst thing Harry had ever seen or felt including the Dementor-induced visions of his mother's death and watching Voldemort return to semi-life.

He loved his mother, he knew he loved both his parents. They had loved him and died for him. But he didn't know that until he was eleven. Before that all his parents were, were another thing for the Dursleys to beat him down with.

But Sirius and Remus…

They were real.

They cared about him and loved him and did the best they could for him without drawing dangerous attention to their flouting of the Headmaster's plan.

To lose one of them and do nothing but watch was against everything Harry was and he proved it in the next second, darting forward and around grasping hands to stop him, his Seeker's reflexes driving him and his quick hands grasping desperately at the edge of the dragonhide battle-robe Sirius was wearing.

Grey eyes were closed thanks to the Stunner, Siri's handsome face resting in dreamless repose and blind to the danger he was in.

Sirius Black was almost lost without ever realizing it.

Unfortunately, Sirius Black was also a large, well-muscled man after spending two years recovering from the ravages of Azkaban, and his weight was too much for a five-foot-nothing Seeker-build wizard of fifteen to handle, Harry being dragged ever forward into the Veil without anything to anchor him to the world behind him.

The sheer weight of Siri's lax body nearly had Harry's grasp losing him before he roared and slung himself forward, grabbing on with the hand still clutching his wand, refusing to give up his godfather to the Veil.

In the seconds it took another set of hands to latch onto Harry's waist from behind, Harry seeing a flash of amber eyes out of the corner of his locked-on-Sirius gaze, the momentum of falling was just too much for even a werewolf to combat in the middle of a battle with no one else seeming to pay attention or even to bother with an Accio which might have saved them from their headlong tumble into the Veil.

It took less than a minute for the Boy-Who-Lived, a werewolf, and an escaped convict to tumble away from the Wizarding World forever, the crack of the Veil sundering and crumbling to dust behind them the only sign of where they'd gone to alert the others of the event that in less than a minute changed the landscape of a war forever.

In the wake of the destructions of the Veil, those of the Chamber unknowing of the battle between Voldemort – wounded and enraged by feeling the link between himself and the Boy break – and Dumbledore who felt the sundering of his tracking charms on said Boy occurring over their very heads in the Ministry Atrium, looked stunned to a man whether witch, wizard, Order, or Death Eater.

At last only the pleased cackling and raving of Bellatrix was all that remained, a cackling that was silenced forever with a quick and ruthless Sectumsempra hissed from the shadows by a formerly-shy teen who had learned the spell from Harry's godfathers.

Neville Longbottom stepped over the bleeding-out remains of the Death Eater, breaking her wand and wand-hand with a vicious crack, and came to stand beside and offer support to the ethereal figure of a bruised but unbloodied Luna.

The Order and Death Eaters quickly recovered, the Order recovering first thanks to the Aurors in their ranks setting off a series of Stunners and Binding Hexes except for Moody who used Avadas while the others turned a blind eye. The loss of the LeStranges to Moody's wand was no great loss in the grand design after all, they were all going to be Kissed after their escape from Azkaban anyway. The grizzled old Auror paused a moment by the pair who were studying the shattered stone and dust that was all that remained of the Veil in silence, one callused paw of a hand coming up to clap the lad on the shoulder and giving him a gruff: Well Done, in regards to his finishing of the Black Witch.

Albus might scold Moody for his lethal spells and would eye the lad harshly if he ever discovered just who it was that ended Batty Bella…but Moody had no intention of playing by Albus's rules this time around. In fact, the Auror rather thought young Neville was just what they needed in the wake of Potter's disappearance. He would have to make sure Augusta was onboard with Moody's plan to train up her grandson before Albus tried to get his hooks in the boy.

This one was made of the right stuff to survive this war and come out – mostly – intact on the other side.

Moody was certain of it.

After the clumping sound of Moody's gait wandered away from the silent pair, Neville turned damp brown eyes on his companion, asking one question.

"Did you know?"

Luna shook her head, a tear falling from momentarily clear blue eyes as her wispy blonde hair floated around her. She'd done considerable damage of her own against the adult Death Eaters, causing more than one broken or shattered bone, one of which was to Fenrir Greyback and unless was treated immediately would likely kill the wolf, shards already dangerously close to his heart. She'd known something was coming, a change, a catalyst for lack of a better term. But she'd had no idea what.

Or that it would cost her one of her only two friends in the process.

"Things will change now." She said in the echoing voice she only used when what she Saw was certain. "For us and for him. Whether for better or worse, only time will tell." She looked away from the remains of the Veil then pointed her wand and incanted: Evanesco, vanishing the shards and dust.

"Luna?" Neville whispered, voice unsteady at her actions.

"They can't find him now." She said simply. "And they would have, after spending too much time and resources on trying to bring back their "Savior"." She sighed. "Now they have to focus on the War. And so do we."

Neville wrapped her up in a hug and they turned away from where the Veil once stood, walking unsteadily but in-step through the ruined chamber and back towards the lifts.

He only had one more thing to ask before he let his first friend rest in whatever peace there might be found on the other side of the Veil.

"Will he be at peace, be happy?"

She hummed lightly under her breath before giving a quiet laugh at what she found.

"In time, maybe." She said without her usual cryptic Code. "But there will be a fight for him before he reaches true happiness."

Neville snorted.

"Of course there will." He rolled his eyes as the lift doors snapped open and they stepped out into chaos. "This is Harry we're talking about. Getting him to accept anything good without a struggle is like trying to take gold from a Niffler."

Author's Note: This is the last you'll see of the Harry Potter world. Our next installment will start in the Walking Dead universe but pre-Series. Gotta give the guys some time to adjust…and see just what is going on with the necklace Luna gave Harry…the Walking Dead characters will be introduced starting in chapter 2…I think…
