Harry Potter: Web of Infinity.

Prologue.

12 year old Harry Potter tore through the trees, turning every so often to fire a spell at the giant spiders, that pursued him. 'Why did I come out here alone?' He thought to himself. 'Why did Hagrid have to tell me to follow the bloody spiders? Damn Ron, the bloody coward. Damn him for turning his back on me. Just because I can talk to snakes, some friend.' He just managed to jump over a fallen log in his path, when something large hit him from the side.

Harry could only watch in horror, as the large acromantula's massive pincers closed on his leg. A scream of pain tore itself from his lips, as the spider's poison flowed into his veins. He was going to die here, eaten by these nightmarish creatures, and no one would know. He would never be able to see Hermione again, or tell her how he felt about her. He would… a loud honking noise broke his musings, as Mr. Weasley's old, enchanted Ford Angelina slammed into the acromantula, sending the massive arachnid flying into the trees.

The beat up car circled around Harry, driving the giant spiders away. Once they were a safe distance, it stopped next to Harry, its driver side door opening. Harry scrambled in as fast as his injured leg would allow, and the car drove off.

By the time the old Ford reached the front door of the castle, Harry was unconscious. The Professors who had heard the honking of the car as it drove up, were horrified at the sight they saw. Severus Snape was quick to pull the dying boy from the car. "Poisoned." He said. "Bitten by an acromantula, it would appear." The Potions Master rushed to the infirmary, the boy he secretly thought of and cared for as a favorite nephew clutched carefully in his arms.

"Oh, Morgana!" Poppy Pomfrey cried out, as the group of Professors entered the ward. "On the bed. Quickly! Severus, I need a bezoar, now." The Hogwarts healer ordered, as Severus set the boy down as gently as he could. He reached into his pocket, and pulled ot the requested stone in his hand, a rare look of concern on his face.

"It may not be enough, Poppy." The sallow faced Potions Master said, as he and Pomfrey cast diagnostic charms on the boy. "There's at least 2 liters of acromantula venom in his system. He should be dead already. It's a miracle he's even still alive."

"Do what you can, Severus." said McGonagall, worry etched across her face. Severus nodded, as he and Pomfrey worked to stabilize the boy. An hour later, and the pair were still working on the boy. They had thought he was stable at one point, but the boy had slipped back to critical.

"Minerva, we can't do this on our own." Snape said, frantically. "Call for a healer from St Mungo's, quickly." McGonagall nodded, and rushed to Pomfrey's office. Five minutes later and she returned, Healer Andromeda Tonk nee Black at her side. Severus quickly explained what they knew of the situation, as the eldest Black sister opened her Healer's satchel.

"I can't believe nothing we've tried has worked." Andromeda growled, 30 minutes later. The trio was nearly at their wits end. "If only we had some Phoenix tears."

"Damn that Lucius Malfoy!" Professor McGonagall hissed, her eyes filling with tears. "We need Dumbledore." As the other Professors in the room voiced their agreement, a soft song filled the room. The group felt their hearts swell with hope, as the song grew louder. As it reached a crescendo, there was a burst of flames above Harry's bed.

When the flames cleared, they saw a beautiful red and gold feathered Phoenix perched on the headboard. Fawkes, Dumbledore's companion, fluttered down to the bed, and hopped along the prone body to Harry's wounded leg. Big silvery tears slid down the fire birds beak, and splashed into the wound. There was a sizzling noise as the tears mixed with the venom that lingered on the skin around the punctures.

As the tears coursed through his blood stream, fighting the acromantula venom, Harry began to thrash around on the bed. "Hold him down!" Andromeda cried, as she, Severus and Pomfrey jumped to do just that. Professor Flitwick showed just why he had been a 5 time World Dueling Champion, as his wand appeared in his hand, and he conjured straps to hold the boy down.

Andromeda, Pomfrey and Severus backed away, just in time as Harry began to glow with a crimson light, and a visible aura of magic built up around him. He began to scream, as his scar split open, and blood mixed with a blackish oozing substance leaked out. A second high pitched voice joined Harry's, as a cloud of pure black magic rose from the oozing scar.

The group of adults gasped in horrified shock, as a face appeared within the black cloud. A face that looked eerily familiar to Severus. The screaming reached a fever pitch, before the black cloud exploded into fine particles, that were swept up by the vortex of crimson magic.

As his magic continued to swirl around him, the Professors soon lost sight of Harry, as the bubble of magic turned opaque. Severus attempted to approach the bubble, waving his wand to cast a diagnostic charm. His magic seemed to bounce of the bubble, and the Potions Master was tossed back to crash into one of the empty beds. After checking on Severus, the group decided to leave the boy be for the time being.

It took 8 hours for the bubble to dissipate. When it did, the Hogwarts Staff stood in shock. Where once had laid a scrawny, malnourished, waif of a boy, now lay a healthy looking young preteen. Harry had gained a healthy amount of weight, in the form of nicely toned muscles. His pale skin had taken on a healthy tan color, and he had gained at least a foot in height.

Andromeda cast a diagnostic charm on the boy, and balked at the results. She turned and asked Severus and Pomfrey to do the same, in order to verify her findings. The two did so, and stared in wonder at the boy. "What is it?" McGonagall asked, worry tinting her voice. "What's happened? Is he alright?"

"He's fine, Minerva." Pomfrey said, shocked. "In fact he's better then fine. His Magical Core has grown and is fully charged. Any lingering effects from the Killing Curse when he was a baby have vanished, and he is in peak physical condition. The only oddities are the small bone growths on his knuckles, and some strange fluid sacks in the skin on his wrists."

"He is sleeping peacefully, now." Severus said, staring fondly at the boy. If the other Professors noticed, they didn't and wouldn't say anything about it to any one. Ever. "Let him rest for now, and we will find out why he was in the Forbidden Forest alone at night when he wakes."

Harry woke with a groan. He felt as if he had run from London to Hogwarts, then been trampled by a dragon. His head was pounding, and his hands and wrists hurt. There was a tingling in the pads if his fingers and toes. He gave another groan as he reached blindly for his glasses.

Someone placed them in his hand, and he put them on. Opening his eyes, he frowned, as the world blurred. He shook his head, took off the glasses and looked around again. Without his glasses he could see better than ever. And the sight that greeted him was not pleasant. Sitting next to him, were two of his favorite Professors. The two he secretly saw as the aunt and uncle he always wanted, but never had.

Severus and McGonagall scowled down at him, expectantly, arms crossed. "You have some explanations to give, Mr. Potter." McGonagall said. "What in Merlin's name would possess you to go confront a nest of acromantula in the Forbidden Forest? By yourself, at night?" Harry blushed and looked away from the looks of disappointment aimed his way by the two people he looked up to most.

"You could have died, Harry." Severus said, softly. Tears welled up in Harry's eyes.

"I had too. Fudge took Hagrid away, and Dumbledore is gone too." He said. Severus and McGonagall softened, as the boy's tears fell. "I had to find out what hurt Hermione, and was taking my family away from me. I was there when Hagrid was taken away. He said to follow the spiders. How was I supposed to know I'd wind up in an acromantula nest. I..i...i.." And with that the boy broke down into sobs of despair.

"Harry. Look at me." Severus said, moving to sit next to the distraught boy. He wrapped his arm around the boy's shoulder, thankful they had moved him to a private room in the ward. McGonagall took the boy's hand in her own. Harry turned his tear streaked face to Severus. "Dumbledore and Hagrid won't be gone for long, and Hermione will soon be back to her old self. But ask yourself this, how would they feel if you had been killed? Minerva and I would have gone with you, if you had but asked. We all care about you and are here to protect you."

McGonagall nodded, drawing Harry's attention. "Now. Why don't you tell us what you found out. Then Madam Pomfrey will check you over."

"I didn't find out much." Harry sniffed, smiling weakly as Severus conjured a handkerchief, and dried the boy's eyes tenderly. "Only that Hagrid was framed for opening the chamber 50 years ago, and whatever the monster really is, the acromantula are scared to name it. Said it was their greatest enemy." Severus frowned, deep in thought, as Madam Pomfrey came in and began waving her wand over Harry.

"Very well. Minerva and I will look into this." Severus said. "And so will you. As part of your punishment, which includes a week of detention with each of us, you are to spend an hour a day researching what acromantula fear. Understand?"

"Yes Uncle Severus. May I visit with Hermione before I leave?" Harry asked. Minerva nodded, and Harry stood, dressed, and after checking with Madam Pomfrey, left. Snape sighed, thinking back to the day Harry had wormed his way into the normally ill tempered Potion Master's heart.

Flashback_

Severus had a bad feeling all day. So much so that he couldn't concentrate on teaching. To make matters worse, his thoughts were on his dearly departed best friend's son. Lily's boy. The child was in danger and Severus couldn't figure out how he knew it.

At lunchtime, he left the castle, and apperated to Little Whinging. It was as he was walking to the door that he heard the pained screams of a child. His wand was in his hand and a curse blew down the door. A quick check of the front rooms revealed nothing. It was in the kitchen that he found a sight that nearly stopped his heart.

There on the floor was a small waif of a boy, his face a mottled mess of nasty cuts and bruises. His arms and one of his legs were clearly broken, and a large beast of a man was in the process of breaking his other leg with a cricket bat.

"It's because...of … your freakishness…. I lost my job…. Boy." The man growled between swings. Near the stove a tall, thin, horse faced woman watched the abuse with a smile. "Should have drowned you as a baby." Vernon Dursley continued. Snape had seen enough.

A quick expelliamus, and the cricket bat went flying from the man's hand. A brace of spells later spells, and both husband and wife were bound and silenced. "HOW DARE YOU!" The Potions master roared. "I should kill the two of you, here and now. To not only blame a defenseless child for your own failures, but to then physically harm him as well. Lily was right about you, Petunia Evans. You are a horrible person. I pity your child, if this is what he has to look up to." A quick pair of wand flicks later and a pair of Patroni flew off through the wall. Minutes later, Albus Dumbledore, and a squad of Aurors entered the house, to find Severus tending to the unconscious Harry Potter.

"Severus? What happened?" Dumbledore breathed in shock.

"I had a bad feeling all day. I don't know why, but I felt it necessary to check on the boy." Severus said, bitter, painful tears of rage barely kept in check, as the boy needed more healing than he could prove. "As I walked up, I heard the boy scream. So I entered and found that… that bastard beating the child with a cricket bat. The bitch was standing there watching. I disarmed him and bound them both, before summoning you and the Aurors, and tending to the boy."

Dumbledore and the Aurors gasped in shock, the Auror healer moving over to Severus and Harry. "The boy needs St. Mungo's. Now." She said, pulling a portkey from her pocket.

"I'm going with you." Severus said. Dumbledore nodded, and the trio vanished in a swirling rainbow of light. The two of the remaining Aurors also pulled out a pair of portkeys and rook custody of the Adult Dursleys. Gawain Robards stalked over to Petunia.

"We'll be taking these two in." Kingsley Shacklebolt growled, taking hold of Vernon Dursley, as

"There should be a second child." Dumbledore said, sadly. He had thought Harry would be safe here. Apparently he had been tragically wrong. The 3rd Auror, Hestia Jones, went in search of the child. She wasn't gone long, as the boy was found in the den, munching happily on biscuits his pudgy little eyes fixed on the telly.

Flashback end_

Severus sighed, the 7 year old Harry had made a full recovery. Dumbledore acknowledged his mistake, and the Ministry' at the headmaster's suggestion had granted Snape with custody of the boy.

With the help from the other Professors, Severus had raised Harry as he thought Lily and James would have. The boy had grown up happy and as healthy as an abused child couldn within the halls of Hogwarts. The students loved the happy child.

Unfortunately, no amount of nutrient potions had reversed the 6 years of malnourishment and abuse the boy had received at the hands of the Dursleys. He was still small and thin. The Dursleys themselves were currently serving a 15 year sentence in muggle jail. Their son, Dudley had been placed into the foster care system.

The former spy knew that the Death Eaters expected him to hand the boy to the Dark Lord, if and when he returned, but Severus would burn in hell before that happened.

It had been 3 weeks since the incident, and Harry was feeling a little odd. His senses felt like they had been supercharged. He could see everything more clearly. Colors were more vibrant than ever. He could hear the muttered conversation that followed him, as though his classmates were speaking normally. His fingers and toes were constantly tingling, and his knuckles and wrists itched like crazy. While Harry had been able to ignore it all for a while, it soon became too much for him.

In Potions that day, he had used the special signals he and his Uncle Severus had come up with to let the Potions Master know that he needed to talk. Snape who was nearby checking on Lavender Brown and Parvati Patil, nodded imperceptibly.

Once dinner had ended that night, Severus had come to collect him. The duo made their way to the dungeon in comfortable silence. Once they were settled in Severus's Quarters, a cup of tea in hand, the man looked at him expectantly.

"I feel weird Uncle Severus." Harry said. "I can see things really well, and I can hear even the quietest of sounds. And something weird is happening with my knuckles."

"Weird how, Harry?" Severus asked. In answer, Harry clenched his fists and flicked his wrists slightly. From the knuckles of both hands, 4 small bony points popped up. Snape grabbed Harry's hands gently, and examined the bone points. He frowned slightly, as small drops of viscous fluid leaked from the tip of the points.

The Professor summoned a small vial to his hand and collected the drops. Harry watched in fascination as Severus examined the liquid, casting several spells on it. "Interesting." The man mused. "It would appear to be a modified acromantula venom. I would suggest being very careful about punching anyone, Harry. Keep your claws retracted at all times."

"Yes Uncle Severus." Harry said. "That's not all though. Watch." Severus arched a brow as the boy turned toward the dueling dummy in the corner. He raised his arm, palm up, bent his middle 2 fingers in and flicked his wrist out. Severus's eyes widened in shock, as what appeared to be spider silk shot from the boys wrist, and stuck to the dummy. Harry yanked the cord like strand of web, and the dummy went sailing across the room to slam into the opposite wall, Harry and Severus ducking just in time.

Harry scrambled through the tunnel, the Basilisk hot on his heels. He flicked his wrist, and shot web at the wall of a cross tunnel using it to turn the corner quicker. The Basilisk rushed past, unable to turn in time. The boy, clad in a crimson and black, skin tight suit, rushed into the main chamber. A flick of his wrist, and web shot toward the ceiling, allowing him to swing up to the top of the statue of Salazar Slytherin. A second web brought the Sword of Gryffindor to his hand.

The shade of Tom Riddle watched, a scowl on his face, as the Basilisk emerged from a larger tunnel. ~Get the boy!~ He hissed in Parceltongue. ~Kill him!~ The Basilisk reared up, bringing its head level with Harry. It roared, and lunged, mouth wide, fangs bared.

Behind his mask, Harry's eyes narrowed. A squeeze of his fists brought out his bone spikes, and as the Basilisk came near, he thrust the sword up and into the roof of its mouth. The fangs of the beast tried to penetrate the crimson dragon scales of Harry's suit, but broke on contact with the magically strengthened material. The Basilisk gave a pain filled scream as the sword pierced its brain. Just to be safe, Harry reared back and punched the roof of the creature's mouth, sending his Venom into the creature.

The beast fell, dead, to the ground. Riddle gave a wordless scream of rage, as Harry swung down to the ground. The Shade calmed itself, and stared at Harry confidently. "So Potter, it would seem you have powers after all. It makes no difference. Ginny will soon be dead, and I will be reborn. Then, Potter, I will kill you."

Harry smirked under his mask. It was just like the muggle comics that Uncle Severus detested, but bought for him anyway. The Villain always spent way too much time on their monologue, when the should just kill the hero. The boy knelt, and picked up the small black diary. Pulling off his mask, and smiled. Riddle stopped talking, and stared at him. "What do you think your doing, Potter? Put that down, now!"

"Not a chance, slime ball." Harry said, and drove his Venom Spikes into the book. Riddle screamed, as a black fluid began to ooze from the book. Harry punched the book three more times. Riddle gave one last scream, and vanished if a black flash of magic.

The motes of magic began to swirl around Harry, turning from black to crimson, and was absorbed into the boy. Harry shuddered, as he felt his magic settle, and closed his eyes. A small moan startled him, and he quickly put his mask back on.

Ginny Weasley sat up shakily, and looked around. "Who are you?" She asked, disappointedly when she saw the masked person kneeling a few feet from her. She had hoped it would be her crush, Harry Potter who rescued her.

"You can call me Crimson Spider, miss." Harry said, trying to make his voice deeper. He knew about Ginny's crush on him. Honestly the girl made him uncomfortable. That she was Ron's little sister, made it worse.

"Oh. What happened?" Ginny asked, seeing the destroyed diary, and the cooling corpse of the Basilisk. Harry looked around, as Fawkes landed on his shoulder, the Sorting Hat in his beak.

"I killed the Basilisk, and destroyed the shade that has been controlling you all year, miss." He said. "You really should be careful who and what you trust. You never know what could happen." Ginny blushed, sheepishly.

"Can we get out of here, please?" She asked changing the subject. Harry nodded, and flipped out a web, pulling the Sword of Gryffindor to him once more. He lead the way out of the Chamber of Secrets, and down the tunnel. When they reached the cave in, where Harry had been separated from Severus, and the fool, Lockhart, he saw that his Guardian had cleared the debris away and shored up the tunnel.

"Oh look. That boy is dressed in strange outfit." Lockhart said. "I wonder who he is." Snape looked up and saw Harry in the skintight dragon hide suit, he had ordered for the boy. 'The mask is new.' He thought.

"I am Crimson Spider, sir. Protector of the Innocent." He said, pointedly staring at Severus through the silver protective eye coverings. His hand, hidden from Ginny was rapidly signaling to Severus, explaining what had happened.

"Thank you Crimson Spider," The man said, nodding imperceptibly to let Harry know that he understood. "For rescuing Miss Weasley. Could you possibly help us out of this place? There is a chute we came down, that we can't climb."

"Certainly, Citizen. Lead the way and I will get us out." Snape turned, and snatching Lockhart by the collar, led the way to the slide. Shooting out 3 strands of webs, he fashioned harnesses around the others, and tying them to his waist, began to climb up the side of the wall, the little hairs that had caused the tingling in his fingers and toes, allowing him to stick firmly to the wall. It was slow going, but finally they were all standing in the 2nd floor girls lavatory.

"Thank you, Crimson Spider." Severus said, signaling for Harry to go to meat the Potions Master in their quarters in the dungeon. "I can take it from here. I'm sure you have other places to be."

"Yes. I do." Harry said, turning to Ginny. "Be more careful from now on, miss. I won't always be there to save you." He told her. Ginny nodded her face bright red, as Harry leapt up the wall and crawled out the window.
