Harry Potter belongs to JK. Rowling.
Fifty massive titans stepped onto the field, stone giants each and every one. Harry Potter stood in the gazebo mounted on the neck of one at the rear. As The Boy-Who-Lived he was far to valuable to stand at the front, but it didn't mean he couldn't see the battlefield clearly. An unexpected lurch as the War-Walker crushed a boulder beneath its massive foot caused Harry fall forward, between two stone pillars that held the delicate bronze roof up. His face, more specifically his nose impacted on an invisible barrier, one that not only protected the people inside the War-Walker from outside attack, but against falling out as well.
"Careful Mr Potter, it would be unfortunate if you were to die of a broken face." sneered Professor Snape.
Turing around Harry's eyes wandred over the interior of the small open-air building. Six seemingly sleeping figures seated in stone chairs surrounding a miniture version of the battlefield, that would be standard in each of the fifty stone titans, but what was not standard was the other people standing around. Severus Snape, Nymphadora Tonks, Cornelius Fudge and two ministry guards were all packed around the sides of the small structure.
Minister Fudge smirked, he would dearly like Harry Potter to die such an ignoble death, just as he was about to speak however the six sleeping wizards simultaneously drew their wands and placed them point down into the table as if it was nothing but soft butter.
"It begins." whispered Fudge.
Turning Harry looked back towards the horizon, thereon the edge he could dimly make out a few flashes of light as muggle tanks fired at the lumbering titans.
Muggle Artillery air-burst around the titans, throwing one to the ground and the wizards within flailing as they were thrown from their seats and bounced around in the shielded building. Fudge chuckled and pointed at the wizards who were quickly retaking their positions and casting the specific spell required to merge them into the War-Walker again. Tonks looked at Harry and pointed at the wizards who were at most bruised. "They'll be right embarrassed about that. Imagine throwing yourself backwards cause somethign flashed in your face." Harry nodded.
The stone titans shrugged off anti-armor rounds from the tanks as if they were nothing, and indeed to them they were naught but that. Eight longer range Surface-to-surface missiles flew in from behind the eastern muggle forces, one of the stone titants waved a massive hand towards them and five beams of light came out of its fingers and guided themselves to the missiles, transfiguring the fuel of each one into non-combustible liquids causing them to drop short and explode on the muggle infantry below. Two more of the missiles were stopped by other titans and the final one impacted upon the outstretched fingers of one of the giant walkers, doing no visible damage... not even a blackened mark upon the stone.
A stone titan lifted its leg to step up a small incline when a tank shot it from mere hundreds of metres away, the impact of the blast pushed the leg backwards, unbalancing the massive construction bringing it down on hands and knees, surviving muggle infantry screamed in victory and lept forward to the gazebo and the wizards sleeping inside. They muggles screamed again as their bodies were immolated by the wards, their dying bursts of fire impacting harmlessly on the shield between each pillar of the gazebo.
The unbalanced titan stood again and made a throwing motion in its hand, a massive fireball leapt from its hand and hit a cluster of muggles, engulfing them in flame and reducing their bodies to ashes in seconds.
A whisper from one of the sleeping wizards behind him caught Harry's attention 'Reducto'. Sparks leapt out of one of the fingers of the titan and dashed forward at an incredible rate to a tank nearly five hundred metres away. As the sparks connected to the tank with impossible accuracy the entire machine exploded, throwing shrapnel around it with lethal abandon.
Harry shuddered as he imagined the screams of the muggle infantry who had just been reduced to little more than minced meat. Tonks draped an arm over his shoulder and pulled him against her side comfortingly, Harry was glad of an excuse to look away from the slaughter.
Mark gestured out into the cavern, from their vantage point high upon the wall Harry and his guide could see a literal sea of giant stonelike figures, each humanoid barring the replacement of their heads with what appeared to be a gazebo held up by six thin stone pillars.
Harry worked his mouth for a moment before words came, "It's amazing, what are they?"
Mark looked down at the boy who lived respectfully and gestured towards the steps, as they moved towards them he began to explain. "These Harry, are the War-Walkers." he stopped at the top of the stairs and points across at the nearest stone figure, six high backed stone chairs sat surrounding a solid stone table. "Six wizards occupy each one where the many spells and enchantments form their minds into one being... one being capable of casting any six spells or more at once."
Harry shivered, One War-Walker full of even mediocre wizards could take on Dumbledore, although the elderly headmaster would most likely win.
"Theres more." Mark continued, "The walkers are charmed to be increidbly magic and physically resistant." The pureblood wizard smirked cruelly. "During the latest muggle world war, they were tested against a german tank division and wiped it out without being scratched, although the wizards were quite sloppy and allowed two shots from the tank to impact on the Walker."
"What about Modern tanks? they're much faster and more powerful than those old ones.." Harry objected.
"We know." Mark said with a nod. "But it won't change a thing, the real reason that Wizards fear giants isn't their monstrous strength, but their ability to destroy magic with physical attacks... a single giant is capable of taking on a War-Walker... compared with that, there is good reason that we deride the muggles."
Harry's mind tried to process it but just couldn't understand it from his perspective, "Giants blows aren't as strong as a modern tank shell though, especially an armor piercing one.." tried the boy bewilderdly.
"It doesn't matter." Mark replied with a shake of his head. "Physical attacks are blunted, for the muggles to be able to even damage a walker they'd have to be able to infuse magic into their weapon's ammunition like almost every magical creature does."
Harry nodded after a moment, "So without becoming wizards, the world could never destroy the wizards?"
Mark winced a little. "Not in combat, well, not without something like hand held nukly-arr weaponry." the wizard shrugged. "We've never been able to test one of those... Magic gets a bit wonked out when they go off you see."
Harry nodded, science class back in primary school had made electric magnets once, and they'd been told about it disrupting electrical things if it was strong enough, like a wave caused from a nuclear bomb. It wasn't unreasonable to believe magic would be disrupted by it when considering magic disrupted electricity as well.
"When six wizards are inside these walkers, they're minds are sort of stacked on top of each other." Mark said as they reached the end of the descending stairs. "A wizard is more dexterous, has more stamina, better eyesight and a few other assorted advantages over muggles. When inside these walkers the wizards can cast spells with unerring accuracy for over a mile, stay awake for a week or more, see insects at over a mile and so on." The wizard paused while he waited for Harry to stop looking at the giant stone foot beside him, as soon as he was being watched again Mark continued. "Now, thats just with human eyes, the War-Walkers use magical eyes in each of the six pillars, these are nearly five times the size of a human eye and capable seeing through nearly anything at a range of less than ten miles."
Harry could see people starting to move among the stone titans, glass orbs were pressed against the ankles of each stone walker where they were absorbed into the rock. "What's happening there?" Asked Harry after a moment.
"The orbs are basically keys. Without one in the titan it won't move or do anything, just a safety procedure to stop Death Eaters and their like from using them." Mark said with a shrug. "I think its time we went back upstairs, if they're unlocking the Walkers we'll be moving out very soon."
Harry took one last look up at the giant stone war-golems. "If the muggles knew... would they have declared war?" asked the boy under his breath before turning his back to follow his guide.
