"It looks just like Rivendell," Aech said, taking the words right out of my mouth.

I nodded. "It looks exactly like Rivendell in the Lord of the Rings movies," I said, still staring up at it in awe. "Og's wife was a big Tolkien fan, remember? He built this place for her."

We heard an electric hum behind us as the jet's staircase retracted and the hatch closed. The engines powered back up and the jet rotated, preparing to take off again. We stood and watched it launch back up into the clear, starry sky. Then we turned and began to mount the staircase leading up to the house. When we finally reached the top, Ogden Morrow was there waiting for us.

"Welcome, my friends!" Og bellowed, extending both his hands in greeting. He was dressed in a plaid bathrobe and bunny slippers. "Welcome to my home!"

"Thank you, sir," Aech said. "Thanks for inviting us here."

"Ah, you must be Aech," he replied, clasping her hand. If he was surprised by her appearance, he didn't show it. "I recognize your voice." He gave her a wink, followed by a bear hug. Then he turned and hugged me, too. "And you must be Wade-I mean, Parzival! Welcome! Welcome! It's truly an honor to meet you both!"

"The honor is ours," I said. "We really can't thank you enough for helping us."

"You've already thanked me enough, so stop it!" he said. He turned and led us across an expansive green lawn, toward his enormous house. "I can't tell you how good it is to have visitors. Sad to say, I've been all alone here since Kira died." He was silent a moment; then he laughed. "Alone except for my cooks, maids, and gardeners, of course. But they all live here too, so they don't really count as visitors."

Neither I nor Aech knew how to reply, so we just kept smiling and nodding. Eventually, I worked up the courage to speak. "Have the others arrived yet? Shoto and Art3mis?"

Something about the way I said "Art3mis" made Morrow chuckle, long and loud. After a few seconds, I realized Aech was laughing at me too.

"What?" I said. "What's so funny?"

"Yes," Og said, grinning. "Art3mis arrived first, several hours ago, and Shoto's plane got here about thirty minutes before you arrived."

"Are we going to meet them now?" I asked, doing an extremely poor job of hiding my apprehension.

Og shook his head. "Art3mis felt that meeting you two right now would be an unnecessary distraction. She wanted to wait until after the 'big event.' And Shoto seemed to agree." He studied me for a moment. "It probably is for the best, you know. You've all got a big day ahead of you."

I nodded, feeling a strange combination of relief and disappointment.

"Where are they now?" Aech asked.

Og raised a fist triumphantly in the air. "They're already logged in, preparing for your assault on the Sixers!" His voice echoed across the grounds and off the high stone walls of his mansion. "Follow me! The hour draws near!"

Og's enthusiasm pulled me back into the moment, and I felt a nervous knot form in the pit of my stomach. We followed our bathrobed benefactor across the expansive moonlit courtyard. As we approached the main house, we passed a small gated-in garden filled with flowers. The garden was in a strange location, and I couldn't figure out its purpose until I saw the large tombstone at its center. Then I realized it must be Kira Morrow's grave. But even in the bright moonlight, it was still too dark for me to make out the inscription on the headstone.

Og led us through the mansion's lavish front entrance. The lights were off inside, but instead of turning them on, Morrow took an honest-to-God torch off the wall and used it to illuminate our way. Even in dim torchlight, the grandeur of the place amazed me. Giant tapestries and a huge collection of fantasy artwork covered the walls, while gargoyle statues and suits of armor lined the hallways.

As we followed Og, I worked up enough courage to speak to him. "Listen, I know this probably isn't the time," I said. "But I'm a huge fan of your work. I grew up playing Halcydonia Interactive's educational games. They taught me how to read, write, do math, solve puzzles ..." I proceeded to ramble on as we walked, raving about all of my favorite Halcydonia titles and geeking out on Og in a classically embarrassing fashion.

Aech must have thought I was brown-nosing, because she snickered throughout my stammering monologue, but Og was very cool about it. "That's wonderful to hear," he said, seeming genuinely pleased. "My wife and I were very proud of those games. I'm so glad you have fond memories of them."

We rounded a corner, and Aech and I both froze before the entrance of a giant room filled with row after row of old videogames. We both knew it must be James Halliday's classic videogame collection-the collection he'd willed to Morrow after his death. Og glanced around and saw us lingering by the entrance, then hurried back to retrieve us.

"I promise to give you a tour later, when all the excitement is over," Og said, his breathing a bit labored. He was moving quickly for a man his age and size. He led us down a spiral stone staircase to an elevator that carried us down several more floors to Og's basement. The decor here was much more modern. We followed Og through a maze of carpeted hallways until we reached a row of seven circular doorways, each numbered.

"And here we are!" Morrow said, gesturing with the torch. "These are my OASIS immersion bays. They're all top-of-the-line Habashaw rigs. OIR-Ninety-four hundreds."

"Ninety-four hundreds? No kidding?" Aech let out a low whistle. "Wicked."

"Where are the others?" I asked, looking around nervously.

"Art3mis and Shoto are already in bays two and three," he said. "Bay one is mine. You two can take your pick of the others."

I stared at the doors, wondering which one Art3mis was behind.

Og motioned to the end of the hall. "You'll find haptic suits of all sizes in the dressing rooms. Now, get yourselves suited and booted!"

He smiled wide when Aech and I emerged from the dressing rooms a few minutes later, each dressed in brand-new haptic suits and gloves.

"Excellent!" Og said. "Now grab a bay and log in. The clock is ticking!"

Aech turned to face me. I could tell she wanted to say something, but words seemed to fail her. After a few seconds she stuck out her gloved hand. I took it.

"Good luck, Aech," I said.

"Good luck, Z," she replied. Then she turned to Og and said, "Thanks again, Og." Before he could respond, she stood on her tiptoes and kissed him on the cheek. Then she disappeared through the door to bay four and it hissed shut behind her.

Og grinned after her, then turned to face me. "The whole world is rooting for the four of you. Try not to let them down."

"We'll do our best."

"I know you will." He offered me his hand and I shook it.

I took a step toward my immersion bay, then turned back. "Og, can I ask you one question?" I said.

He raised an eyebrow. "If you're going to ask me what's inside the Third Gate, I have no idea," he said. "And even if I did, I wouldn't tell you. You should know that...."

I shook my head. "No, that's not it. I wanted to ask what it was that ended your friendship with Halliday. In all the research I've done, I've never been able to find out. What happened?"

Morrow studied me for a moment. He'd been asked this question in interviews many times before and had always ignored it. I don't know why he decided to tell me. Maybe he'd been waiting all these years to tell someone.

"It was because of Kira. My wife." He paused a moment, then cleared his throat and continued. "Like me, he'd been in love with her since high school. Of course, he never had the courage to act on it. So she never knew how he felt about her. And neither did I. He didn't tell me about it until the last time I spoke to him, right before he died. Even then, it was hard for him to communicate with me. Jim was never very good with people, or with expressing his emotions."

I nodded silently and waited for him to continue.

"Even after Kira and I got engaged, I think Jim still harbored some fantasy of stealing her away from me. But once we got married, he abandoned that notion. He told me he'd stopped speaking to me because of the overwhelming jealousy he felt. Kira was the only woman he ever loved." Morrow's voice caught in his throat. "I can understand why Jim felt that way. Kira was very special. It was impossible not to fall in love with her." He smiled at me. "You know what it's like to meet someone like that, don't you?"

"I do," I said. Then, when I realized he had no more to say on the subject, I said, "Thank you, Mr. Morrow. Thank you for telling me all of that."

"You're quite welcome," he said. Then he walked over to his immersion bay, and the door irised open. Inside, I could see that his rig had been modified to include several strange components, including an OASIS console modified to look like a vintage Commodore 64. He glanced back at me. "Good luck, Parzival. You're going to need it."

"What are you going to do?" I asked. "During the fight?"

"Sit back and watch, of course!" he said. "This looks to be the most epic battle in videogame history." He grinned at me one last time, then stepped through the door and was gone, leaving me alone in the dimly lit hallway.

I spent a few minutes thinking about everything Morrow had told me. Then I walked over to my own immersion bay and stepped inside.

It was a small spherical room. A gleaming haptic chair was suspended on a jointed hydraulic arm attached to the ceiling. There was no omnidirectional treadmill, because the room itself served that function. While you were logged in, you could walk or run in any direction and the sphere would rotate around and beneath you, preventing you from ever touching the wall. It was like being inside a giant hamster ball.

I climbed into the chair and felt it adjust to fit the contours of my body. A robotic arm extended from the chair and slipped a brand-new Oculance visor onto my face. It, too, adjusted so that it fit perfectly. The visor scanned my retinas and the system prompted me to speak my new pass phrase: "Reindeer Flotilla Setec Astronomy."

I took a deep breath as the system logged me in.

I was ready to rock.

My avatar was buffed to the eyeballs and armed to the teeth. I was packing as many magic items and as much firepower as I could squeeze into my inventory.

Everything was in place. Our plan was in motion. It was time to go.

I entered my stronghold's hangar and pressed a button on the wall to open the launch doors. They slid back, slowly revealing the launch tunnel leading up to Falco's surface. I walked to the end of the runway, past my X-wing and the Vonnegut. I wouldn't be taking either of them today. They were both good ships, with formidable weapons and defenses, but neither craft would offer much protection in the epic shitstorm that was about to unfold on Chthonia. Fortunately, I now had a new mode of transportation.

I removed the twelve-inch Leopardon robot from my avatar's inventory and set it down gently on the runway. Shortly before I'd been arrested by IOI, I'd taken some time to examine the toy Leopardon robot and ascertain its powers. As I suspected, the robot was actually a powerful magical item. It hadn't taken me long to figure out the command word required to activate it. Just like in Toei's original Supaidaman TV series, you summoned the robot simply by shouting its name. I did this now, taking the precaution of backing away from the robot a good distance before shouting "Leopardon!"

I heard a piercing shriek that sounded like rending metal. A second later, the once-tiny robot had grown to a height of almost a hundred meters. The top of the robot's head now protruded through the open launch doors in the hangar ceiling.

I gazed up at the towering robot, admiring the attention to detail Halliday had put into coding it. Every feature of the original Japanese mech had been re-created, including its giant gleaming sword and spiderweb-embossed shield. A tiny access door was set into the robot's massive left foot, and it opened as I approached, revealing a small elevator inside. It carried me up through the interior of the robot's leg and torso, to the cockpit located inside its armored chest. As I seated myself in the captain's chair, I spotted a silver control bracelet in a clear case on the wall. I took it out and snapped it onto my avatar's wrist. The bracelet would allow me to use voice commands to control the robot while I was outside it.

Several rows of buttons were set into the command console in front of me, all labeled in Japanese. I pressed one of them and the engines roared to life. Then I hit the throttle and the twin rocket boosters in each of the robot's feet ignited, launching it upward, out of my stronghold and into Falco's star-filled sky.

I noticed that Halliday had added an old eight-track tape player to the cockpit control panel. There was also a rack of eight-track tapes mounted over my right shoulder. I grabbed one and slapped it into the deck. Dirty Deeds Done Dirt Cheap by AC/DC began to blast out of the robot's internal and external speakers, so loud it made my chair vibrate.

As soon as the robot was clear of my hangar, I shouted "Change Marveller!" into the control bracelet (the voice commands appeared to work only if you shouted them). The robot's legs, arms, and head folded inward and locked into new positions, transforming the robot into a starship known as the Marveller. Once the transformation was complete, I left Falco's orbit and set a course for the nearest stargate.

When I emerged from the stargate in Sector Ten, my radar screen lit up like a Christmas tree. Thousands of space vehicles of every make and model were crawling through the starry blackness around me, everything from single-seater craft to giant moon-sized freighters. I'd never seen so many starships in one place. A steady stream of them poured out of the stargate, while others converged on the area from every direction in the sky. All of the ships gradually funneled together, forming a long, haphazard caravan of vessels stretching toward Chthonia, a tiny blue-brown orb floating in the distance. It looked like every single person in the OASIS was headed for Castle Anorak. I felt a brief surge of exhilaration, even though I knew Art3mis's warning might still prove true-there was a chance most of these avatars were here only to watch the show and had no intention of actually risking their lives to fight the Sixers.

Art3mis. After all this time, she was now in a room just a few feet away from me. We would actually be meeting in person as soon as this fight was over. The thought should have terrified me, but instead I felt a zen calm wash over me: Whatever was going to happen down on Chthonia, everything I'd risked had already been worth it.

I transformed the Marveller back into its robot configuration, then joined the long parade of spacecraft. My ship stood out in the vast array of vessels, since it was the only giant robot. A cloud of smaller ships quickly formed around me, piloted by curious avatars zooming in for a closer look at Leopardon. I had to mute my comlink because so many different people were trying to hail me, asking who the hell I was and where I'd picked up such a sweet ride.

As the planet Chthonia grew larger in my cockpit window, the density and number of ships around me seemed to increase exponentially. When I finally entered the planet's atmosphere and began to descend toward the surface, it was like flying through a swarm of metal insects. When I reached the area around Castle Anorak, I had a hard time believing my eyes. A concentrated, pulsing mass of ships and avatars covered the ground and filled the air. It was like some otherworldly Woodstock. Shoulder-to-shoulder avatars stretched to the horizon in all directions. Thousands more floated and flew through the air above, dodging the constant influx of ships. And at the center of all this insanity stood Castle Anorak itself, an onyx jewel gleaming beneath the Sixers' transparent spherical shield. Every few seconds some hapless avatar or ship would inadvertently fly or careen into the shield and get vaporized, like a fly hitting a bug zapper.

When I got closer, I spotted an open patch of ground directly in front of the castle's entrance, just outside the shield wall. Three giant figures stood side by side at the center of the clearing. The crowd around them was continuously surging inward and then receding as avatars pushed back against each other to try to keep a respectful distance from Aech, Art3mis, and Shoto, who each sat inside their own gleaming giant robot.

This was my first opportunity to see which robots Aech, Art3mis, and Shoto had selected after clearing the Second Gate, and it took me a moment to place the towering female robot Art3mis was piloting. It was black and chrome in color, with elaborate boomerang-shaped headgear and symmetrical red breastplates that made it look like a female version of Tranzor Z. Then I realized it was the female version of Tranzor Z, an obscure character from the original Mazinger Z anime series known as Minerva X.

Aech had selected an RX-78 Gundam mech from the original Mobile Suit Gundam anime series, one of his longtime favorites. (Even though I now knew Aech was actually a female in real life, her avatar was still male, so I decided to continue to refer to him as such.) Shoto stood several heads taller than both of them, concealed inside the cockpit of Raideen, the enormous red-and-blue robot from the mid-'70s Brave Raideen anime series. The massive mech clutched his signature golden bow in one hand and had a large spiked shield strapped to the other.

A roar swept through the crowd as I flew in low over the shield and rocketed to a halt above the others. I rotated my orientation so that Leopardon was upright, then cut the engines and dropped the remaining distance to the surface. My robot landed on one knee, and the impact shook the ground. As I stood it upright, the sea of onlookers began to chant my avatar's name. Par-zi-val! Par-zi-val!

As the chanting faded back to a dull roar, I turned to face my companions.

"Nice entrance, ya big show-off," Art3mis said, using our private comlink channel. "Did you show up late on purpose?"

"Not my fault, I swear," I said, trying to play it cool. "There was a long line at the stargate."

Aech nodded his mech's massive head. "Every transport terminal on the planet has been spitting out avatars since last night," he said, motioning to the scene around us with his Gundam's massive hand. "This is unreal. I've never seen so many ships or avatars in one place."

"Me neither," Art3mis said. "I'm surprised the GSS servers can handle the load, with so much activity in one sector. But there doesn't seem to be any lag at all."

I took a long look at the sea of avatars around us, then shifted my attention to the castle. Thousands of flying avatars and ships continued to buzz around the shield, occasionally firing bullets, lasers, missiles, and other projectiles at it, all of which impacted harmlessly on the surface. Inside the sphere, thousands of power-armored Sixer avatars stood in silent formation, completely encircling the castle. Interspersed through their ranks were rows of hover tanks and gunships. In any other setting, the Sixer army would have appeared formidable. Maybe even unstoppable. But in the face of the endless mob that now surrounded them, the Sixers looked woefully outnumbered and outmatched.

"So, Parzival," said Shoto, turning his robot's huge head in my direction. "It's showtime, old friend. If that sphere doesn't come down like you promised, this is going to be pretty embarrassing."

" 'Han will have that shield down,' " Aech quoted. " 'We've got to give him more time!' "

I laughed, then used my robot's right hand to tap the back of its left wrist, indicating the time. "Aech is right. It's still six minutes to noon."

The end of my sentence was drowned out by another roar from the crowd. Directly in front of us, inside the sphere, the massive front doors of Castle Anorak had just swung open, and now a single Sixer avatar was emerging from within.

Sorrento.

Grinning at the din of booing and hissing that greeted his arrival, Sorrento waved his hand at the Sixer troops stationed directly in front of the castle and they immediately scattered, clearing a large open space. Sorrento stepped forward into it, positioning himself directly opposite us, just a few dozen yards away, on the other side of the shield. Ten other Sixer avatars emerged from the castle and positioned themselves behind Sorrento, each of them standing a good distance apart.

"I have a bad feeling about this," Art3mis muttered into her headset.

"Yeah," Aech whispered. "Me too."

Sorrento surveyed the scene, then smiled up at us. When he spoke, his voice was amplified through powerful speakers mounted on the Sixer gunships and hover tanks, allowing him to be heard by everyone in the area. And since there were cameras and reporters from every major newsfeed outlet present, I knew his words were being broadcast to the entire world.

"Welcome to Castle Anorak," Sorrento said. "We've been expecting you." He made a sweeping gesture, indicating the angry mob that surrounded him. "I must say, we are a bit surprised so many of you showed up here today. By now it must be obvious, to even the most ignorant among you, that nothing can get past our shield."

His proclamation was met with a deafening roar of shouted threats, insults, and colorful profanity. I waited a moment, then raised both of my robot's hands, calling for quiet. Once a semblance of silence had descended, I got on the public comm channel, which had the same effect as turning on a giant PA system. I dialed my headset volume down to kill the feedback, then said, "You're wrong, Sorrento. We're coming in. At noon. All of us."

A roar of approval erupted from the assembled gunters. Sorrento didn't bother waiting for it to die down. "You're welcome to try," he said, still grinning. Then he produced an item from his inventory and placed it on the ground in front of him. I zoomed in for a closer look and felt the muscles in my jaw tighten. It was a toy robot. A bipedal dinosaur with armor-plated skin and a pair of large cannons mounted on its shoulder blades. I recognized it immediately, from several turn-of-the-century Japanese monster flicks.

It was Mechagodzilla.

"Kiryu!" Sorrento shouted, his voice still amplified. At the sound of the command word, his tiny robot instantly grew in size until it stood almost as tall as Castle Anorak itself, twice the height of the "giant" robots that Aech, Shoto, Art3mis, and I piloted. The mechanical lizard's armored head almost touched the top of the spherical shield.

An awestruck silence fell over the crowd, followed by a rumble of fearful recognition from the thousands of gunters present. They all recognized this giant metal behemoth. And they all knew it was nearly indestructible.

Sorrento entered the mech through an access door in one of its massive heels. A few seconds later, the beast's eyes began to glow bright yellow. Then it threw back its head, opened its jagged maw, and let out a piercing metallic roar.

On cue, the ten Sixer avatars standing behind Sorrento pulled out their toy robots and activated them, too. Five of them had the huge robotic lions that could form Voltron. The other five had giant mechs from Robotech and Neon Genesis Evangelion.

"Oh shit," I heard Art3mis and Aech whisper in unison.

"Come on!" Sorrento shouted defiantly. His challenge echoed across the crowded landscape.

Many of the gunters on the front lines took an involuntary step backward. A few others turned and ran for their lives. But Aech, Shoto, Art3mis, and I held our ground.

I checked the time on my display. Less than a minute to go now. I pressed a button on Leopardon's control panel, and my giant robot drew its gleaming sword.

I didn't witness it firsthand, but I can tell you with some certainty that this is what happened next: The Sixers had erected a large armored bunker behind Castle Anorak, filled with pallets of weapons and battle gear that had been teleported in by the Sixers before they activated their shield. There was also a long rack of thirty Supply Droids, which had been installed along the bunker's eastern wall. Due to a lack of imagination on the part of the Supply Droids' original designer, they all looked exactly like the robot Johnny Five from the 1986 film Short Circuit. The Sixers used these droids primarily as gofers, to run errands and fill equipment and ammo requisitions for the troops stationed outside.

At exactly one minute to noon, one of the Supply Droids, designation SD-03, powered itself on and disengaged from its charging dock. Then it rolled forward on its tank treads, across the bunker floor, to the armory cage at its opposite end. Two robotic sentries stood outside the armory's entrance. SD-03 transmitted its equipment requisition order to them-an order that I myself had submitted on the Sixer intranet two days earlier. The sentries verified the requisition and stepped aside, permitting SD-03 to roll into the cage. It continued past long storage racks that held a wide array of weaponry: magic swords, shields, powered armor suits, plasma rifles, railguns, and countless other weapons. Finally, the droid rolled to a stop. The rack in front of it held five large octahedron-shaped devices, each roughly the size of a soccer ball. Each device had a small control panel set into one of its eight sides, along with a serial number. SD-03 found the serial number that matched the one on my requisition form. Then, following a set of instructions I'd programmed into it, the little droid used its clawlike index finger to enter a series of commands on the device's control panel. When it finished, a small light above the keypad turned from green to red. Then SD-03 lifted the octahedron in its arms. As it exited the armory, one antimatter friction-induction bomb was subtracted from the Sixers' computerized inventory.

SD-03 then rolled out of the bunker and began to climb a series of ramps and staircases the Sixers had built onto the castle's outer walls to provide access to the upper levels. Along the way, the droid rolled through several security checkpoints. Each time, robotic sentries scanned its security clearance and found that the droid was allowed to go anywhere it damn well pleased. When SD-03 reached Castle Anorak's uppermost level, it rolled out onto a large observation platform located there.
