Prologue

Hogwarts School of Witchcraft and Wizardry
September 1st, 1995, Scotland, UK

The time of darkness is at a standstill.
A magic veiled under green, shall rock our world.
And the world outside the realm of magic,
Shall fear the light of green...
Both worlds with lost souls, collected and sealed,
To fuel a monster thought long and ancient.
The evil lord temporarily sealed,
Returns when the green magic is destroyed.
For you see, the lord when he returns,
Returns with no memory... returns to his plans of
World domination and purity of blood...
A hero with a past far greater that he knows,
Shall take the mantle of the other saviour,
And destroy the darkness that plagues the light
Once of course his own destiny is revised...
As I tell you this, shall I remind you all?
That you are brave when the magic reveals,
And Godric's Home shelters our courage.
The students, who work hard, are home to Helga,
As she takes in who show their spirit...
The brains of the class, the hard thinkers of the rest,
When you arrive, Rowlena bids you welcome.
And the cunning of the rest, those how show pride,
Salazar's home, shields the students of emerald.
The time of darkness is at a standstill,
However, only temporary...
Beware the Green Magic, for the heroes arrive...
They combat against the Green Magic...
The Legendary Dragons shall arrive in our world...
Controlled by the heroes who appear to save us all...

No one said a word as the Sorting Hat became silent once again. Only a select few understood the hints of that Sorting Hat's Opening Speech. And once again, why does this point to that magic that the Order discovered truly by accident over the summer? Dumbledore feared that dark terrifying magic that emanated from these strange gold objects that seem to exist and at the same time not exist. Harry and Cassandra were brought into the whole mess, once a wizard and a witch.

Harry and Cassandra are no longer one of them... because this dark magic had burned their cores away, only to be revealed as a host to magical spirits that now live within them, as souls. And if that wasn't enough, around the month of August, random muggles have been found hospitalized. Further searches found out they had lost their souls, but the Dementors have yet to have left the Prison of Azkaban. Nor have any of the victims undercover Aurors found out show no signs of being kissed.

As he decided to think this through at a later time, he bids McGonagall to begin with the Sorting.

"Alexander, Harrison," McGonagall called out the first name off the list.

Halfway across the world, a man looks up, fingering a green stone in his hand.

"I can never get used to these uniforms," Harry said, as they returned home from school the next morning.

"Don't sweat it. It grows on you. You just like wearing your own clothes," Mokuba replied, as the younger Kaiba had followed the duo to their place. The two closed the door to the bedroom, and began changing, while Mokuba raided the fridge and snagged himself a can of Cherry Pepsi before planting himself in Harry's favorite recliner.

"So Harry... how is that Blue-eyes White Dragon of yours?"

"It's well. Surprising that I'm one of the other duelists who owns a Blue-eyes other than Seto," Harry responded back, through the crack of the bedroom door, getting dressed.

"Surprised Seto didn't try and take it from you," Mokuba stated, flipping the channels with the remote.

"Whatcha think of this?" Cassie asked Harry.

"Looking great on you, dear. Too bad guys who try and peek at you will get punched."

"You jealous?" She asked in a sly manner.

Mokuba shook his head having heard that bit from the living room. "Wish they'd keep it to a minimal," he muttered.

After seeing his two best friends getting real frisky on Harry's birthday... they still have a photo of his brother somewhere of when he was complaining about needing some Tylenol after he had saw the duo on the bed paused in mid-rut. Mokuba looked up when the door to the bedroom had opened twenty minutes later and the duo had stepped into the living room.

Harry's new clothing consisted of woodland camouflage cargo pants, with the standard black belt with his Dueling deck strapped to the right of his hip alongside a second deck strap. He had a set of chain links hanging of his left hip. The sneakers were dark green with white stripes and black laces, and the socks were a light gray. He wore a baggy fishnet shirt overlapping a white tank, wearing a fleece unbuttoned dark gray vest with an oval pauldron covering his right shoulder. Accessories worn was a necklace with two charms of a lightning bolt and a stave dangling from the silver chain, and one hell of an expensive looking, silver blue-tint Rolex watch on his right wrist, which Kaiba had got him for his fifteenth birthday (quite a surprise too for everyone else, even Mokuba).

Cassandra's new clothing consisted of black jean shorts with two chain links connecting off the right pant leg to her dark gray belt with her two deck straps hanging off her right hip. She wore navy and white striped sneakers with pink shoe laces, black socks, and had a gold bangle with a red oval gem hanging off her left ankle. Like Harry, she wore a baggy fishnet shirt overlapping the black strip of cloth that covered her assets, wearing a half-zipped white hoodie with the gray sleeves, the red kanji in vertical over the right sleeve spelling out "One-Winged Fox". Accessories other than the gold jeweled bangle, was a silver necklace with two charms of a fox head and a feather, her ears pierced with small pink teardrop earrings, and her own wristwatch, only suited for the outdoors.

"Looking good," Mokuba said after giving the once-over with the two.

The two smiled. "We should get you your own set of fashion too. We gotta look good after all," said Harry," when we're not in school of course."

"Maybe. Let's hurry up. I want to beat the traffic to Burger World."

"We can then stop by the mansion. Since tomorrow is the weekend, we can stay over for the night."

"Awesome. We can watch mid-night movies and such." Cassie snatched the keys, and their Duel Disks. Harry's was a now customized model. Instead of the traditional white, the Duel Disk of his was colorized after his signature monster Pretty Girl Maya, with pink colors replacing the gray portions, blue replacing white and golden yellow replacing red.

Harry as the trio walked down the street, pulled out Maya's Duel Monsters card, staring at her image depicted on it, surrounded by a pink border. Maya was that special to him, as Kochi was to Cassie, since her signature card had a lavender border.

"You know... I'm very surprised you two haven't been caught yet."

"Oh, because of that thing we did in the west side boy's restroom?"

Mokuba glared. "You guys could have been caught!"

"So, it was out of order! It was a perfect place for us."

"I just wish you two would keep your secret activities to a minimal, especially in a public place such as school." The two teenagers blushed, remembering what they did two weeks ago.

"Come on, Mokuba... if you and Rebecca ever get together, I'm sure you two would have done the same, if not something equally similar."

Mokuba scoffed at that idea, though his cheeks were starting to burn. "At least I would withhold on my desires. I don't know which is worse, you two or horny cats."

The two looked at one another, and then back at Mokuba. "We're corrupting you, Mokuba-kun!"

He sweatdrops. Tell me about it...

"It is going close to two years Bellatrix, and still our lord and master has not awaken," complained her husband.

"I know that... we'll still try however. Severus is helping after all, and keeping up the duties master has set for him, a spy on Dumbledore and the Roasted Turkeys."

"What about Malfoy... he had swooped in after his brother was locked in Azkaban, and stolen the money that supports our very cause, and left his family in the gutters of Nocturne Alley."

"He'll be found, and then once he's killed, Draco can inherit the money, and then we'll work on freeing Lucius from Azkaban..."

Meanwhile, a group of newbie Death Eaters, practically Slytherin graduates of Hogwarts, the group of seventeen cornered a man in an alley somewhere in Italy. The victim they chased turned around wearing a necklace with a glowing green stone.

"Charter Malfoy, you have what we need, now die so we can claim it back!"

Jets of green light fired from their wands when the name of the spell was shouted out, but suddenly a shield of magic erupted around Charter. The green stone glowed more vividly, stunning the group as the Killing Curse has been blocked completely.

"The Killing Curse was supposed to be unblockable! No one survives!" One of them yelled.

"Ha! Unblockable my ass!" He cackled, as the group of seventeen stared in horror, "You think your wizarding magic is enough to save you all... oh, just wait! Witness true magic!"

He gripped the stone at the end of the chain and instantly a powerful green glow appeared. A green column of light engulfed him, stretching upwards into the sky further than anyone could see in this near secluded area of Italy. The seal's arcane six-pointed star burned into the ground with a vivid glow, as the circle lined with runic-like symbols. And he gazed back at them, his eyes tinted red, and the seal, but much smaller, now was branded upon his forehead.

"Your souls are too weak, therefore I cannot let you live... you shall simply die. Come forth to me, Orichalcos Gigas (4/400/1500)!"

To the Death Eaters, appearing in a flash of green light was an ugly brute of a troll, broken chains shackled to its wrists, and garbed in tattered brown rags for a tunic, with metal straps crossing the large muscled chest, and wrapped around the forearms and ankles. Its head was dwarfed by its immensely large body, large arms, legs, and powerful fists; however it snarled and beat its chest with a war cry. The wizards and witches immediately feared for their lives, ran, but then smashed into the barrier that had them all trapped. Charter Malfoy laughed manically as Gigas attacked them, returning to life and gaining more strength when they kept firing Killing Curses at it. It got too powerful that the Killing Curse no longer affected it, with the Attack Position strength of six thousand and four hundred points; it had reduced them to bloody smears.

They were in all aspects dead. Gigas vanished as the seal faded away. He had no doubt he was discovered what with all the uses of the Unforgivables upon Gigas, so he made a quick get away, snatching a rope ladder that flew through the area, connected to a helicopter flown by his partner, Gregory Rain. As the heli flew off into the distance pops echoed signaling the appearance of the Italian Ministry Aurors, taking in the sight of the English Death Eaters: dead. One Auror ran to the nearest garbage and hurled at seeing one of the heads smashed wide open with the brain matter smeared across the bloody ground.

"Che cosa è accaduto qui?" The chief who led this group of Aurors muttered, sickened by the sight of brutal death. Nonetheless, this warranted investigation.

"Now gentlemen... you have a job to do. You are to travel to Domino City, Japan, and find the three Egyptian God Cards. After you have collected them, one of you shall draw out the controller of the God Cards, and trap him within a Seal Duel."

"Of course, boss," was the reply.

"Malfoy, Rain. I wish for you to remain hidden. When the time comes, you Malfoy may duel against Mr. Potter, and Rain may duel against Miss Black. Until then, remain hidden. Understand, gentlemen?"

"Yes, sir," they replied.

The man with long sea green hair smiled malevolently. "Good. Dismissed."

The time has come...
