Before I get onto the story, a bit of an update. Progress is slow on Loving the Alien, Our Hearts are Stolen Goods, and Virtute non Armis Fido. Part of this is due to my motivation to write lately being on a low ebb, and each story has its own individual problems to deal with. I'm hoping to post at least one of them as a full story in the future, but ATM, it's not looking good. Hopefully, that will change.

Also, I've posted another poll on my profile. Check it out.

Now, this story idea is a tentative one. It's a WBWL fic with a Honks pairing (Harry aged up a few years) and James-bashing, inspired by DZ2's 'Project Zeus' challenge...and it's a crossover I haven't done before, but have intended to for quite a while. Namely, JoJo's Bizarre Adventure.

I'm actually going along a similar line to what I've done with Overlord in Yield to the Darkness, in that I am integrating characters from JoJo's Bizarre Adventure into the Potterverse, with a different version of their history. How different? Well, Jonathan is still alive by this point (and the Potterverse version of the Phantom Blood arc took place in the 50s here), Joseph is his son as opposed to his grandson (with Elizabeth/Lisa Lisa and Holly being Joseph's siblings), and Jolyne and Jotaro are Jonathan's grandchildren by Joseph and Holly respectively. Yeah, I know this is gonna piss off the purists of JoJo's Bizarre Adventure, but given what happens at the end of a certain story arc, I think it can boil down to continuity reboots and multiverse theory being a bitch.

Oh, and Harry and Tonks are now Pillar Men. No, really.

POST TENEBRAS SPERO LUCEM

CHAPTER 1:

DISCOVERY

There was an air of impatience to the handsome blonde-haired man…if you could call him a man any more. Now, his features had something of the diabolical beauty of Satan himself, with the same darkness and danger. He rapped his fingers irritably on the armrest of the chair he was seated on, before finally, the door opened, and a Chinese man in a labcoat appeared, walking into the dim office. "Well?"

The Chinese man bowed briefly, not the style of bow often used in China and Japan as a matter of etiquette, but rather, something less formal but certainly more deferential. "Sir, we have finally gotten a report, albeit with extreme difficulty. As we suspected, that facility was raided by the Speedwagon Foundation."

"Hmm…it seems that they have gotten lucky…or perhaps their intelligence-gathering has become better. Or perhaps we have a mole. A traitor amongst the ranks. Well, we will sniff them out in due course. Tell me, Wang Chan, were the test subjects destroyed or taken?"

"Evidence suggests that they have been taken away, sir," Wang Chan said. "Though given the lineage of one of them…"

"Yes…and we never perfected a means of controlling them. We'd only finished concluding the hybridisation experiments and the tests of their abilities," the leader mused. "Not a complete disaster, as we know now that it works. Still, while we kept little sensitive data onsite, we should ensure that we move our headquarters again, and see if we can secure the other sites. And the Stone Masks were taken?"

"Most were destroyed, but there is evidence that some were removed, sir," Wang Chan said.

"Hmm. Well, it's a fair bet to know that they were taken to the Speedwagon Foundation. No doubt that old fool and his backers are putting their researchers onto the matter. With any luck, they will destroy them outright. And if not…well, I, Dio, will have the means to deal with them in any case…"

The Speedwagon Foundation. A non-profit R&D organisation founded in the Fifties by former street hoodlum and now oil tycoon Robert EO Speedwagon, funded by his corporation. Medical research, archaeology, engineering, Speedwagon was very much a rags-to-riches success story, and he was known to have a link to the Joestar family, a long-established line of British nobles.

But people didn't know that the Speedwagon Foundation also had a remit to investigate the unexplained and supernatural, or at least what most people would consider to be such. And it had been waging a shadow war for decades against another organisation in the shadows, an organisation led by someone who was once one of their own. Not to mention against various creatures that were considered to be myth.

They were tolerated, at best, by the various magical governments of the world. At worst, they were considered an enemy, for while the Speedwagon Foundation employed many mages, it was run by those without magic, for the most part. The relationship was particularly contentious in the Joestar's native Britain, and in the US, where Speedwagon had made much of his fortune. Mages in both countries were particularly hidebound, and felt that the Speedwagon Foundation and the Joestars, despite their links to magic and their efforts to help the dispossessed in both countries, were upstarts and disruptors of the natural order.

However, a true spark that was about to ignite a conflagration of conflict between Magical Britain and the Joestars and their allies had been ignited when, upon acting on a tipoff from an informant, they had raided the bases of one of their greatest adversaries…

In the training room at the Speedwagon Foundation, a blue-haired man, burly, but with an air that made him seem like a gentle giant (and indeed, a gentleman), gently breathed in a specific, rhythmic fashion. He appeared to be in his forties, but was actually in his sixties. He sparred with what looked like a young man with similar features, but brown hair and a more cocky demeanour, and a blonde-haired man who had the air of a playboy. As they fought, strange yellow sparks seemed to crackle around their bodies, intense like the Sun.

Soon, the sparring match was over, and the blue-haired man smiled. "Good work, both of you. You've learned some new skills while training under Master Tonpetty."

"Of course, whaddya expect, pops?" the brown-haired young man asked with a grin.

The blonde rolled his eyes. "Your son's ego still needs deflating, Signor Joestar."

The blue-haired man, Jonathan Joestar chuckled. "And yours does not, Caesar? It's little wonder Master Tonpetty chose Elizabeth as his protégé to make into his successor."

"Well…she is a worthy successor," Caesar admitted. "A shame it was not a Zeppeli, but…well, that is beside the point. Signor Joestar, why did we bring back those…things from Dio Brando's laboratory? My father made it his life's mission to destroy the Stone Masks and their vile creations, not to mention their creators."

Jonathan Joestar blinked, before he walked out of the room, heading for the changing room. As the other two followed him, he said, "Caesar, I understand your reluctance, and I too share it. However, we need to understand what Dio is doing. He was experimenting not only with the Stone Masks, but also hybridisation with the Pillar Men."

Both Caesar and the brown-haired young man stopped. "Whaddya talking about, pops? That's crazy!"

"Well, Dio Brando is not exactly a paragon of sanity, Joseph," Jonathan said. "However, it is not wholly out of the question. We have no reason to believe that human and Pillar Men DNA are not compatible, given that they presumably evolved from a common hominid ancestor. And given that we have evidence of someone taking samples from a number of the Pillar Men we discovered…Dio presumably intended to try and exploit their abilities."

"Still, bringing in those two is dangerous," Caesar said.

"Dangerous, yes, but I doubt that they were willing volunteers, Caesar," Jonathan said. "Indeed, I recognise them. And frankly, so should you, Joseph."

"What?"

"Let's put it this way. You have a son, from an affair."

Joseph, after a moment, put his hands to his face in shock, and yelled, eyes wide, "OH MY GOD!"

"…He has a son? I mean, he has a child apart from little Jolyne?" Caesar asked. "Does Suzi know about this?"

"It was from before they met," Jonathan said. "It was back in 1975, during the Voldemort War. He'd just graduated from school, and she had just graduated from Hogwarts."

"Hogwarts? A witch, then?"

"Yes, a Muggleborn."

"…Lily," Joseph said quietly. "But…she died, didn't she?"

"No. But we'll get to that later. Along with the two unfortunates, we found her in a tank of liquid, on life-support. We've managed to transport it here, and we have specialists working on her. However…of greater concern are the two hybrids Dio created. Given that they were involuntary test subjects, I am reluctant to destroy them until I can be sure they will cause trouble. The few Pillar Men we have actually encountered are ruthless, true, but they were the followers of Kars, and Wamuu showed that they weren't wholly evil. And these two were human once."

"And one of them was my kid?" Joseph asked. He blinked. "Wait, if he is my kid with Lily, then that means…"

"Yes. He is Harry Potter, the older brother of the Boy Who Lived, Charles Potter. James Potter claimed that Harry was kidnapped by Death Eaters nine years ago. It seems that these Death Eaters sold Harry onto Dio."

Joseph scowled. "Not that Potter'd give a damn. Remember when we encountered him while trying to deal with that vampire? And that was before he stopped being an Auror and went into politics more."

"Your next line will be 'he's as bad a Pureblood as Malfoy, even if he pretends to be Light'," Caesar said.

"He's as bad a Pureblood as…son of a bitch! Caesar, it's no fun if I'm not the one doing it!" Joseph snapped.

"Come on, you two," Jonathan said. "Let's get changed, and then see our new guests…"

Jotaro Kujo glared through the thick glass at the two sculptures in the chamber, bathed in UV light. It wasn't out of any real antipathy towards the statues themselves that he glared, rather, glaring was his default expression, a sullen scowl. Like many Joestar men, he was tall and burly. He was dressed in his favoured variant of his school uniform.

He had been dragged here to England by his mother, partly to see the relatives, and partly because apparently it was time for him to learn more about the family business, so to speak. Well, at least it wasn't mafia or yakuza.

"So, what the hell am I looking at?" he asked the older woman sitting nearby, his grandmother, Erina Joestar, née Pendleton.

"Mind your language, Jotaro," Erina chided. Jotaro had to admit, while the woman was very much an old-fashioned British woman, like something out of a Jane Austen novel or something, she nonetheless had a strong inner fire, even in her sixties. "Though to be honest, what you see is hellish, the result of hellish experimentation at the very least. Has your mother told you about Dio Brando?"

"Gramps told me, and so did Uncle Joseph," Jotaro said. "Son of a thief, got adopted by Gramps' father, tried to usurp Gramps in the will…turned himself into a vampire. Sounds like something out of a bad horror movie or some manga series."

Next to him, a girl of his age with beautiful but sharp features snorted, her dark hair having a blonde fringe at the front, and a pair of horns done up on her head. "Got that right. Dad also told me about these…Pillar Men, weren't they called?"

Erina nodded, and a blonde-haired man in his sixties walked over to the glass. The scar bisecting his handsome features was a relic of his days spent as a hoodlum. "Yeah," he said, his voice still having a Cockney accent to it. "The Pillar Men were offshoots of humanity, Jolyne, a bit like vampires in some ways. We think the original vampire myths, along with those of the wendigo and of the troll, come from them. They are ridiculously long-lived, capable of absorbing nutrients directly through their body and shaping their body to suit their needs. Their one main weakness was sunlight. It petrifies them. Hence the UV lamps. We managed to figure out the exact wavelength for keeping them dormant, as few people can learn to use the Ripple."

"But these two are not natural-born Pillar Men. They were created through the experiments of Dio Brando," Erina said.

Jotaro looked once more at the two sculptures. They depicted a young man and a young woman, about his and Jolyne's age, maybe a little older, both naked, curled up in the rock. Both had small horns, the young man having one on the left side of his forehead, while the young woman had two. "Are they friendly or not?"

"Hopefully, the first one," the older man said. "They've been identified as Harry Potter, and Nymphadora Tonks. They'd been kidnapped during an outing to Hogsmeade back in '85. Death Eaters were blamed."

"Those British wizard terrorists Mum told me about?" Jotaro snorted. "Didn't Voldemort kick the bucket in 1981, Speedwagon?"

"Allegedly, but remember, many of them escaped the clink by claiming to be under the Imperius, which is bollocks," Speedwagon said. "But, well, there are sheeple everywhere."

Both Jotaro and Jolyne snorted. "Got that right," Jolyne muttered.

Jotaro nodded. Of all his relatives, he got along best with Jolyne, who had the same fire and acerbic tongue that he did. They were cousins, but they might as well have been twin siblings. Or father and daughter…now that was a weird thought.

Then, his grandfather, Jonathan Joestar, along with his uncle Joseph and his godfather Caesar Zeppeli, walked into the observation room. "No change, yet?"

"Not a damned thing, Jonathan. It's a relief…but given who these two are…"

"Yes. We can bring the UV lamps down to a level where they are not petrified, only weakened?"

"I spoke to the technicians, and yes, it's possible. You want to make sure they're not gonna go all Darth Vader on us?"

Jonathan nodded. "Great minds think alike, Robert. These two, I believe, are innocents in Dio's scheme, unless he's managed to indoctrinate them."

"There weren't anything found in their heads from the scans we did, JoJo," Erina said, smiling at her husband. Jotaro thought it sickeningly sentimental, especially how his grandfather looked younger than his grandmother. "But…perhaps potions?"

"No residues of any potions were found. That we know of. Even in that state, we'd be able to detect something," Speedwagon said. "So…do we do it?"

"Dial it down," Jonathan said.

The intensity of the UV lamps was brought down. Then, cracks ran down the surface of the stone of the sculptures, before suddenly, and improbably, actual people seemed to come out of them. What had been stone had become flesh.

Both had athletic, muscled builds, not quite the towering pillars of muscle the Pillar Men had been (or that many Ripple users were, too, Jotaro reflected), but muscled all the same. The woman had pink hair that changed colours, while the man had shaggy dark hair and emerald eyes.

"…What the hell happened?" the woman asked, before looking at the man. "Oh, wotcher, Harry. Is it me, or are we in a different place?"

"Well, we're in a different lab to Dio's," the man said, before looking up. The observers weren't looking through a one-way mirror, so the man was looking at them.

Jotaro was a bastard, he knew that much. He was an infamous delinquent back home. He'd put more than a few people who pissed him off into the hospital (and some were still there). He'd put uppity teachers in their place, sometimes forcing them to resign. And at restaurants where the food wasn't up to snuff, he'd do a dine-and-dash. But he also liked to think that he knew evil when he saw it. And what he saw wasn't evil. Dark, yes, dangerous, yes, but evil? No, he was looking at a confused human being.

Jonathan cleared his throat, before saying, "Harry Potter? Nymphadora Tonks?"

"Hey, don't call me Nymphadora!" snapped the woman angrily.

Jolyne chuckled. "I like her."

"Sorry about your current accommodations. I'm hoping they will be purely temporary. I'm Jonathan Joestar. Welcome to the Speedwagon Foundation."

Harry and Tonks looked at each other, and then back at Jonathan. Wariness was in their gaze…but then again, so too was the faintest embers of an emotion they clearly hadn't felt for a long time. A seductive, deadly emotion…and yet one of the greatest.

Hope.

CHAPTER 1 ANNOTATIONS:

Well. That just happened. So, Harry and Tonks have been turned into Pillar Men hybrids, and now they're in the custody of the Speedwagon Foundation.
