Harry Potter: Green Lantern's Light

Prologue

June, 1993

Harry James Potter was standing on platform 9 ¾ having just stepped off the Hogwarts Express having completed his second year. His best friends Hermione and Ron followed him and they pulled their trunks behind them as they headed off to find their rides. The Weasleys were found first and after a series of goodbyes and Harry was nearly squeezed to death in a hug by Molly Weasley, the gaggle of red heads were off to the Burrow. Next, the green eyed wizard and his bookish friend found the elder Grangers and after introductions, Hermione gave Harry one of her own famous bone-crushing hugs and a kiss on the cheek and walked off with her parents while Harry stood there, absently touching his cheek with an expression of wonder on his face. Finally, he shook it off and looking around, noticed that everyone had cleared out pretty much and headed over to the public Floo. A bit of research on magical travel had given Harry a number of options and he intended to make use of one. Stepping up confidently, he grabbed a bit of Floo powder and tossed it into the flames calling "Leaky Cauldron" and stepped into the flames and vanished.

A few moments later, the messy haired teen stumbled out of the Floo at the Leaky Cauldron and taking a quick couple of steps, managed to avoid falling on his ass (he was glad he had studied Floo travel, especially the notes on how to travel safely and effectively). Walking over to the counter, he noticed the pub was practically deserted, which suited him perfectly. As he reached the counter, Tom the old barman appeared.

"Mr. Potter! Wonderful to see you lad, how can I be helping you today?"

"A room would be great, maybe for the whole summer Tom, would that be possible?"

The barman studied him for a moment, taking in the boy's appearance, the ragged clothes and his small size, then he gave the lad a smile, "Yes, I think we can manage that Mr. Potter."

Harry grinned, "Brilliant."

The barman then grabbed a key off the peg and levitated Harry's trunk, "Follow me then lad."

A short while later, ensconced in his room, which had a decent view of Muggle London, Harry was staring out at the city and thinking. He needed to change, he needed to prepare. Two years of schooling as a wizard now and during both he had faced an incarnation of Voldemort and some extremely dangerous magical animals. He was blundering along, no plan, no real skill, just a lot of luck and good friends. He charged blindly into dangerous circumstances any sane person would avoid like a bull driven mad by a red rag. It was time for a change, time for the intellect he had hidden since his first year in Muggle elementary school to make a comeback. To that end, Harry had just sent a letter to Professor McGonagall requesting to change his electives, dropping Divination to take Ancient Runes instead. Harry planned to get some money the next day, do some clothes shopping and locate a martial arts teacher and speak to them about private lessons. He also planned to devote his summer to improving his grasp of the last two years of Hogwarts material, working to fully understand the theory while at the same time he would be using a stick to practice his wand movements and casting speed. He also planned to study ahead in his materials and be much more prepared this time. Harry fully intended that his third year would be different, he wouldn't hold himself back anymore. He would still most likely be in the middle of whatever craziness this year brought, but he would be READY.

The next morning, Harry enjoyed a pleasant stroll down the Alley to Gringotts, as he stepped inside the Goblin run bank he saw a familiar face and walked over.

"Hello Griphook!"

The tiny goblin looked up at Harry in surprise, humans never remembered their names. Recovering himself, Griphook responded, "Mr. Potter, it is agreeable to see you again."

Harry smiled, careful not to show teeth, as his research had indicated that was offensive to goblins, "And you, I was hoping to speak to someone about my account today, I have never received any statements and I don't really know what I have."

Griphook frowned, "No statements? That's impossible Mr. Potter, I assure you they were sent."

Harry nodded, "I have no doubt, my guess is they were intercepted by someone, who does not want me to know what is available to me as it would give me options that I might not otherwise have. And please, call me Harry."

The goblin studied him for a moment, then nodded, "Follow me please, Harry." With that, he led Harry into the offices behind the counters. Eventually, they stopped outside a door with two signs, one in the goblin language, and one in English, which said 'Inheritance Department'. Griphook knocked and opened the door when the occupant answered, they spoke briefly in their language, while Harry stood, waiting patiently.

Finally, the second goblin stood, he was larger than Griphook, stockier, with the look of someone who knew his way around a weapon. He beckoned Harry into the office and gestured to the chair in front of his desk. Harry walked in and sat.

"Mr. Potter…"

"Harry, please sir, just Harry."

"You may call me Goldtooth. Harry, Griphook tells me that you have received no account statements and are unaware of your entitlements and holdings? Is that correct?"

"Yes sir, I know I have my school vault, but my research indicates that the Potter Family had much more than that."

"Much more indeed young Harry, the Potters are one of the wealthiest families in the world, magical or muggle. As the sole heir, you are entitled to all of it and as you are also the only living direct descendent of Godric Gryffindor, you are the heir to that line as well."

Harry's eyes went wide and his mouth dropped open, "Gryffindor? I'm the heir of…." Harry studied the two goblins. "Someone was supposed to inform me weren't they?"

"Oh yes, young Harry, on your 11th birthday you should have been informed by your guardian and brought to see the family vaults and accept the heir's rings."

Harry frowned, "My Aunt and Uncle are my guardians, but they despise magic… and me. And if they knew I was rich, they would have taken it all and left me nothing."

The goblins looked at each other and frowned and then Griphook spoke, "Harry, your guardian is Albus Dumbledore."

"WHAT?!"

XXX

After Harry had been calmed down, they spoke for a while and the goblins made several suggestions as to how they might help the young wizard, which he readily agreed to. The goblins would not even charge him, as they considered it reward enough to help thwart the plans of Albus Dumbledore, who while not evil was very annoying with his constant speeches on forgiveness and 'the Greater Good'. The goblins then took Harry to a healer for a physical and a blood test to see if he was eligible to inherit any other bloodlines. The healer was shocked and quite appalled at the young human's physical condition. It was decided that they would need to give Harry treatment immediately, for the abuse and neglect he had suffered, to correct the damage to his body and magic and perhaps most importantly, to rid him of the soul fragment in his scar.

The healer looked grim, "Harry, you are malnourished, underweight, short for your age and your magic has been damaged. This is one of the worst cases I have ever seen and it seems that you have something in your scar that is sapping your magic, drawing on it, and limiting you to a fraction of your real power." The healer paused, "There is good news however. We can reverse all the physical damage, as well as the damage to your magical core and our curse breakers can cleanse the scar granting you access to all your magic. The downside is it will take time."

Harry nodded, "How long?"

"Four to six years, including treatment and training to improve your health and adapt you to your new power level."

"Six years, but I don't have that long." Harry slumped and looked down, he had been so close!

Goldtooth spoke, "Time, young Harry, is not a problem, Gringotts has a set of chambers that will allow you to receive the full course of treatment, in only a few days."

Harry frowned, "But, the healer said it would take years…"

Goldtooth smiled, "Tell me Harry, what do you know about temporal magic?"

After a long discussion, it was agreed that Harry would be treated in the Gringotts time dilation chambers. Inside, time would pass much faster, but thanks to a special ward, Harry would not age, even though his body would change as he recovered from a lifetime of abuse. The goblins retrieved his belongings and assisted in his procurement of clothes and other necessities, as well as his books for Hogwarts.

All in all, Harry spent just over six years subjective time in the chambers, but only six days passed in the outside world. He had been fully healed, the curse in his scar had been removed and with it the constant drain on his magic, though the constant pull had worked his core and as a consequence, made it expand exponentially making him incredibly powerful. This had the benefit of making Harry feel better than he ever had, like a massive weight had been lifted off him, it also gave him full access to his magic, whereas he had been operating at about 20% previously. He learned Occlumency in order to protect and organize his mind. He also reviewed everything from his first two years at Hogwarts and the books for Charms, Defense, Transfiguration and Runes from third year up to fifth year and spent a great deal of time on spell casting with both hands, working on his speed and accuracy and adjusting to his new power levels. He began training in wandless magic as it was determined he had a natural aptitude for it. He also underwent physical training: push-ups, pull-ups, running, swimming, fencing and martial arts. This improved Harry's physique and greatly increased his stamina. He also received training in dueling and magical combat and discovered he was a gifted fighter, with an innate grasp of tactics and astonishing situational awareness. His instructors and healers could not be more pleased with his progress.

As he completed the six years/days, Harry felt better than he ever had and knew that he was now ready to face the year ahead at Hogwarts. He was fit, healthy, no longer needed his glasses, had a new wardrobe and was finally comfortable with himself. He had gained a few inches of height and was now 5' 8" and had put on muscle, now coming in at a respectable 130 pounds, and was now above average height and weight wise for his age. He had the lean build of a swimmer, or acrobat and had no complaints. Hopefully, a certain bookworm would notice and be happy with the changes too. His scar had faded a bit, but the goblins had told him it would always be there, scars of that nature never fully healed, though it would continue to slowly fade as he got older.

Leaving the chambers, Harry was met by Goldtooth. "Ah Harry, looking much better I see!"

"Thanks to you both and Gringotts. I am so grateful to you all; I can never repay what you have done for me."

The goblin shook his head, "Nonsense my boy, it was we who are in your debt, you vanquished the Dark Lord, giving us respite from his constant pressuring and you have been wronged by the bank as we have not upheld our duties in your case. We are the ones that owe you my young friend and the debt can never be repaid."

Harry smiled, "We'll just have to agree to disagree then."

The goblin chuckled, "Indeed we shall. If you will come with me, I have the results of your inheritance test and we can discuss them and your plans in my office."

When they arrived, Harry took the chair in front of Goldtooth's desk and waited for the goblin to begin.

"Harry, as you know, you are the sole heir to the Potter and Gryffindor lines, these come through your father. You are also listed as the heir to the Black estate, being the nearest male relation to the main line and the designated heir of the current Lord Black. Now, we have found that you are also the sole heir to the Ravenclaw and Hufflepuff lines through your mother and you are the heir of the Slytherin line by right of conquest because of your defeat of Thomas Riddle Jr., the previous heir." The goblin paused and studied the boy in front of him, "What this all basically means Harry, is that you are the single richest being on the planet, magical or muggle. Your total assets are well over 12 billion galleons liquid, with another 10 billion in properties and investments. With the current conversion rate of 10 British Pounds to the Galleon, you are worth approximately 220 billion British Pounds, or 400 billion US Dollars."

Harry Potter had faced a Cerberus, a basilisk, Voldemort, and other terrors that most adult wizards would run screaming from while tearing out their hair. He had endured years of abuse and had not broken, but finding out he was the richest person in the world was just too much, Harry Potter, the Boy Who Lived, fainted dead away.

Harry awoke a short time later, to find an amused looking Goldtooth studying him, "Back with us Harry?"

Harry groaned and nodded, "Yes, no more big shocks please."

Goldtooth chuckled, "That was the majority of it. You might be interested to know that you own Hogwarts and the Hogsmeade Valley including the land the village is built on, and the Forbidden Forest. You also have an island in the Caribbean that is unplottable and hidden from the muggles with an extensive Goblin Ward Array. You also own the property in Godrics Hollow, though it has been declared an historical preservation site by the Ministry, so you can't build there. Sadly the majority of the Potter properties were destroyed during the last two Dark Lord's wars of conquest. The Black Family assets are not available to you at this time, though they will be if the current Lord, Sirius Black dies. I have here your rings, if you would please put them on your left index finger, one at a time, they will all merge and you can make the ring invisible, or display any of them as you wish."

Harry complied, putting the rings on one at a time. As he did, he felt the family magic link with his own. He also received knowledge on politics, etiquette and protocol and other useful information for dealing with Purebloods. The rings would also provide him with legal advice as needed and coach him on his duties as a Lord. The rings would be most helpful.

Harry spent the remainder of the summer working on his accounts and estates with his new account manager, Griphook. He practiced what he had learned in the chambers, the goblins allowed him to make use one of their training rooms to cast spells each day. He exercised and practiced his martial arts and fencing skills. Hogwarts was in for a big surprise.

September 1st, 1993

Harry arrived on Platform 9 ¾ at 10am on September 1st, his new trunk, which had a runic array that allowed it to be shrunk and enlarged with a wand tap was stored in his pocket, his familiar Hedwig was already winging her way towards Hogwarts and Harry was enjoying the relative quiet as only a handful of students had arrived this early. He was hoping to see one in particular. When he spotted her, his breath hitched for a moment and his heart sped up, there was Hermione, the beautiful bookworm that held his heart. He strode over, a mischievous smirk creeping onto his face.

"Excuse me miss, would you have the time?"

Hermione jumped slightly, startled by the voice behind her. She turned and looked up at the young man who had spoken and thought he seemed awfully familiar, when she reached his eyes, doubts fled and her jaw dropped open, "Harry?"

He smiled and nodded.

She grabbed him in a bone crushing hug, then pulled back and tried to give him a stern look, though it was hard since he looked so amazing she could barely form coherent thoughts and his body when she hugged him… "Harry James Potter! Why didn't you write to me this summer?"

Harry instantly looked contrite, "I'm sorry Mione, I was off the grid, undergoing some training and getting myself better. The Dursleys…."

She nodded, "Its ok Harry, I just missed you SO much! So, you had a good summer then?"

His face broke into a wide smile, "The best ever, the only way it could have been better is if you had been there."

Hermione blushed, "Harry!"

Harry chuckled, "I mean it, I really missed you too." He pulled her into another hug, "It's SO good to see you Mione."

She beamed at her best friend, a slight blush still gracing her cheeks, her parents who were watching the teens, looked at each other and grinned. Their little girl was smitten and apparently Harry was too. They stepped forward.

"Harry, you remember my parents?"

"Of course, how are you sir, ma'am?

"We are quite good Harry, and please call us Dan and Emma. Well, we need to be going; you kids have fun at school and Hermione dear, do remember to write." With a wink, the elder Grangers left and the two blushing teens went to find a compartment. It was going to be a good year.

After an encounter with a Dementor on the train and meeting their new DADA Professor, the kids finally made it to school. The year seemed to pass much as always, homework and exams, insults from Malfoy and a new danger in the form of Sirius Black, the man accused of betraying his parents to Voldemort. Harry learned the Patronus Charm in order to combat the Dementors that seemed so interested in him after he was nearly killed in the season opener Quidditch match against Hufflepuff and he began training Hermione, teaching her what he had learned over the summer, he also helped her to build a fitness regimen, began training her in fencing and found she already had experience with martial arts, as she had studied Tae Kwon Do for several years. They sparred, teaching each other their respective styles, practiced their spell casting and got to know each other even better. Finally, around Christmas, Harry mustered up his courage and asked her to be his girlfriend.

At the end of the year, they used Hermione's Time Turner to save a hippogryph and Sirius Black once they had figured out he was innocent, Harry, cornered with his unconscious godfather, fired a Patronus that destroyed or drove off over 200 Dementors and then managed to capture Peter Pettigrew, the real traitor, allowing for Sirius name to finally be cleared and giving Harry a positive place to go for the summer.

Over the summer, Harry and Hermione trained, studied and had a great deal of fun, hanging out at her house, or with Sirius. Though, at the end of the summer, the events at the Quidditch World Cup and the escape of Peter Pettigrew from Azkaban cast a pall on their happy times.

When they returned to Hogwarts, they continued training, studying and kissing every chance they got. The announcement of the Tri-wizard tournament was ignored, until on Halloween night, Harry's name came out of the Goblet. Yet again, his life was in danger through no direct fault of his own. After he proved he had not entered or asked anyone to enter him by swearing a magical oath in the great hall in front of everyone, it was stated that no matter who entered him, it was a binding magical contract and he had to compete or lose his magic. Sadly, even with the oath, Ron's jealousy got the better of him and Harry broke all ties with one of his first friends.

Harry and Hermione, with their new friends Neville Longbottom, whom they had begun helping the previous year and Luna Lovegood, an eccentric Ravenclaw that was being bullied by her housemates, trained hard for the Tournament, their sole goal to ensure Harry's survival. They succeeded admirably as the powerful young wizard easily won each of the tasks. At the end of the Third Task, in June of 1995, Harry found himself in a graveyard in Little Hangleton, with Cedric Diggory after grabbing the Tri-Wizard Cup together, which turned out to be a portkey. They fought together and defeated Wormtail, only to be ambushed by Voldemort who killed Cedric and captured Harry. They took some of his blood and used it in a dark ritual to give Voldemort a new body, then he called for his servants…

After the Dark Lord had pontificated on his absence and had punished a few of his followers, he returned Harry's wand and tried to force him to submit, but Harry shrugged off the Dark Lord's Imperius Curse. Now free and armed, Harry battled the Dark Lord and managed to escape with the body of Cedric Diggory to tell everyone the Dark Lord had returned. To shut Fudge up, he once again proved that he was telling the truth with a magical oath in front of the audience in the stands (with a sonorous charm) and then survived yet another assassination attempt, this time by the fake Moody, who turned out to be Barty Crouch Jr., who had 'died' in Azkaban.

That night, Harry stood with Hermione; they were alone in the Astronomy Tower quietly looking out over the grounds while Harry pondered the events of their 4th year and in particular that night while he held his girlfriend. He had given the winnings from the tournament to the Weasley twins to help them start their dream joke shop and he had carefully avoided everyone else in the wake of the Tournament, except his Mione, whom he had brought with him to find some peace.

As they stood there, they saw a green glow on the horizon, heading towards the castle. It swept in glowing brighter and brighter, finally coming to a stop and hovering before them and they saw a ring was the source of the glow. Then, a voice issued forth.

"Harry Potter of Earth, you have the ability to overcome great fear… Welcome, to the Green Lantern Corps."

With that, the ring flew forward and slid onto Harry's right middle finger and Hermione stepped back as a green glow enveloped the young wizard. When the glow dimmed, Harry stood garbed in a green and black suit that hugged his body. It was a black suit, with glowing green trim around the high collar and shoulders, glowing green cuffs on each of his forearms, glowing green boots, and a glowing green belt with a silver buckle with a green circle and two bars on it. The same symbol was present in the silver circle on Harry's chest, except this one was glowing a bright emerald green. Harry's eyes seemed lit from within and a dim, greenish glow surrounded his body.

The voice spoke again, "Your training will commence in one week, please make preparations."

With that, the glow flared again and Harry stood there in his previous clothing, looking down at the ring in awe. Hermione, seeker of knowledge and closet superhero enthusiast, was aware of the Green Lantern Corps and as far as she knew, Hal Jordan and Jon Stewart were the current Green Lanterns for Earth's sector. She hoped nothing had happened to them. Seeing the awe and confusion on Harry's face, she walked to him and gave him a kiss, then took his hand and began an explanation of what a Green Lantern was and what wearing the ring meant.

A week later, Harry stood with a duffel bag at his feet, alongside Hermione, her parents and Sirius at Grimauld Place, which thanks to their efforts and the efforts of Dobby, Harry's elf, was much changed from its previous haunted house image. Everyone watched in awe as Harry's ring flared and in a flash of light, he stood garbed as a Green Lantern.

He smiled and hugged Sirius, Hermione and Emma and shook hands with Dan. Then he backed up and faced them all and hefted his bag onto his left shoulder, "I'm not sure how long I'll be gone, but I am hoping to be back in August so we can spend time together before school starts." With that, he turned and headed outside, his family following. And as he cleared the house, he turned once more and was hit with a bushy haired missile as Hermione gave him one last hug and kiss, as they broke apart he touched her cheek, "I'll miss you too, I love you Hermione." With that, his aura flared and the green eyed seeker shot up into the sky, quickly vanishing into the clouds above.

As she watched him go, tears running down her cheeks, Hermione whispered, "I love you too Harry Potter, please come back to me soon."
