G. Lippert - James Potter and the Curse of the Gatekeeper

James turned back, looking up into the smug face of his nemesis.

"Do it," the Gatekeeper hissed. "Kill him now!"

Lucius growled, "You cannot! You're weak!"

"I'm not!" James sobbed. He tightened his grip on the wand and pointed it directly at the taller man's heart. And then, with blissful suddenness, assurance washed over him. He wasn't weak. He could do exactly what he had to do. In his mind, he heard both Helga Hufflepuff and Merlin's voices: the right thing to do is always simple, but it is never easy.

"I am a warrior," James whispered to himself, gritting his teeth. "And the sign of a true warrior… is knowing when not to fight."

With that, James lowered the wand. He dropped it, and then turned his back on Lucius Malfoy. Slowly, he began to walk away.

"James Sirius Potter!" the Gatekeeper shouted. "You cannot turn aside! Kill him! You owe it to the world! You owe it to yourself and your father! You cannot deny the power I am offering you!"

James looked at his grandfather sadly, his heart breaking. Arthur smiled proudly and nodded at him.

"Strong, that boy is," Sirius said, his eyes black and sparkling. "Just like his father before him."

Slowly, the pools of light faded. Arthur and Sirius descended into darkness.

James kept walking. He was nearly at the edge of his own circle of light when he heard Lucius Malfoy's voice behind him.

"If you will not kill to become the host of the Gatekeeper," he said, his voice oozing hatred, "then I will!"

James knew that Lucius had picked up Ralph's wand. He felt it pointing at him. He stopped in his tracks, not turning around.

"Avada Kedavra!" Lucius hissed, spittle flying from his lips with the force of his rage. The bolt of green light sizzled through the air and struck James squarely in the back. James felt the force of it, and it pushed him forward slightly. Still, he did not turn. He stood precisely on the edge of light and shadow.

Lucius stared at the boy, his eyes narrowed and a grimace of hatred carved on his face. The boy should fall now; he was dead. Lucius waited, still holding the rough, green-tipped wand, still pointing it at the boy's back.

There was a faint ripping sound. A long, ragged tear suddenly separated along the fabric of the Darkbag on James' back, spreading from the point where the Killing Curse had struck it. James felt movement in the Darkbag. Something was awakening inside it. Many somethings, in fact, and they were hungry.

"What kind of trick is this?" Lucius drawled nervously, taking a step backwards. He eyed the rip in the Darkbag as a noise began to emanate from it. James steeled himself, curling his hands into fists. The noise increased, becoming a loud, busy thrum. And then, violently, the Darkbag erupted. Borleys poured from the hole where Lucius' Killing Curse had ruptured it. They'd tasted the raw magic of the curse, and they wanted more. They streamed through the air toward Lucius like a cloud of bats.

Lucius' eyes bulged at the sight of the advancing Borleys. Instinctively, he waved the wand at them, firing spells randomly. Jets of light blared from the wand, and the Borleys went into a feeding frenzy, ravenous and strengthened by the magic. They fell on Lucius in a cloud.

James finally turned, letting the shredded Darkbag slip from his shoulders. When he looked back, Lucius was completely engulfed in the Borleys. They swarmed over him, devouring him alive. He screamed as they feasted on him, sucking the magic from him, vampirelike. He seemed to be shrinking. He collapsed to his knees, unseen through the boiling, shadowy mass. It was horrible, and yet James couldn't bring himself to look away. Finally, Lucius' body seemed to completely come apart. He dissolved into a sort of crumbling ash and crumpled to the floor, his last scream rasping, echoing into nothing. Satisfied, the Borleys exploded away, screeching and vanishing wildly into the darkness. Within seconds, they were gone, lost in the Void.

James stepped forward. What was left of Lucius Malfoy poured out of his sleeves and the neck of his robe like ashen powder. James knelt and, very carefully, plucked two things from the crumbling dust of Lucius' hand. As he stood, he pocketed one of them: Ralph's wand. The other, he held in his hand, feeling the small, dark power of it.

"Put that down," the Gatekeeper ordered, and its voice had changed, become deeper, less human. "You know not what you have done."

James shook his head. "I know exactly what I've done," he said.

"You cannot defy me!" the Gatekeeper roared, and it revealed itself once more. It no longer looked human, however, but like an enormous cloud of swirling smoke and ash. Eyes swarmed through the cloud, all of them furious, glowing red. "No one can defy the Gatekeeper! Release the stone! You cannot contain its power!"

"That's true," James said, no longer afraid of the Gatekeeper, "but I know someone who can."

He turned, somehow knowing that Merlin would be standing nearby. Perhaps James had even somehow caused him to be there. He walked over to the big wizard and held out his hand. In it, the ring sparkled brightly. Darts of light flashed off the black facets of the Beacon Stone.

Merlin smiled a slow, humorless smile. Gently, he took the ring and placed it on his finger, seating it alongside its twin.

"And now," Merlin said, raising his hand, "as your earthly Ambassador and bearer of the complete Beacon Stone, I command you! This is not your world, nor shall you occupy it! Begone, Beast of the Abyss, Gatekeeper of the Void! I banish you to the nothingness that shall forever be your home! Depart this moment, and never return!"

The cloud of ash and smoke roared. It made to fall upon Merlin, attempting to consume him, but a sudden, enormous crack of vivid light appeared in the darkness, slashing it open. The roar of the Gatekeeper turned into a shriek as it was pulled upward, toward the crack. It fought against the force, spinning and writhing, and for a moment, James thought it looked like a huge, inverted cyclone. And then, with a blinding flash and a clap of thunder, it was gone, banished back to the Void from which it had come.

James blinked in the silence. He took a deep breath and turned back to Merlin, exhausted.

"Is it gone?" he asked. "Gone for good?"

Merlin nodded slowly. "The door between the worlds is shut."

It was over. James turned to look back, curious to see if there was any remaining sign of that blinding crack into which the Gatekeeper had vanished. There was nothing but blackness and silence. And then—

There was a flash and James stumbled; light and noise exploded around him. He squinted, gasping for breath in the sudden noise and rush of air; he was back on the rear of the Hogwarts Express engine again, as if he'd never left it. Trees blurred past, just as before, but when James looked out over the coal car behind him, the air was bright and clear.

"The Dementors are gone!" he called to Merlin.

"Sent back to the Void along with their master," Merlin agreed, nodding.

James grinned in relief, and then suddenly remembered the train's perilous destination. "We have to stop the train!" he yelled, his eyes widening. "It's going to go off the unfinished bridge! Everyone on board will be killed!"

Merlin nodded again, his face turning grim. Once again, James opened the door of the engine compartment. Instead of darkness, however, this time he found a cramped interior space, stiflingly hot. At the front of the compartment was a bank of incomprehensible dials and gauges. Above this, two broad windows looked out over the oncoming track.

"Which one is the brake?" James called, scanning the dials and levers helplessly.

"That large lever on the floor," Merlin replied, pushing up his sleeves. "Grip the handle and pull as hard as you can, James. No matter what happens, don't let go."
