Chapter One; The Summoning I

A powerful rumble shook the grounds of the Institute of War; it was not due to an earthquake, but something more reckless and destructive. The magical orbs that brought light to the otherwise dark cavern shook as the quakes continued. Although the cavern the Institute was located in shielded the structure from any external magic that could interfere with its practices, if the place were to be plunged into darkness, the result would be just as disastrous.

High Councilor Heywan Relivash stood in a chamber filled with anxious summoners, all frantically preparing for the ritual that would occur then. The Councilor abhored doing such a heartless act as this, but the circumstances he faces were not normal to begin with.

The orb closest to him rolled off its perch and shattered into large, azure pieces when it struck the marble floor. Its light dimmed for a moment before the magic vanished.

"You there! Get another light in here now!" commanded Heywan amid the chaos.

His voice was heard, and a novice summoner scrambled to place another orb onto the stand. His young hands shook not from his superior's tone, but from the direness of the situation. Heywan felt it too, but his role as a leader prevented him from showing it.

It was either do or die, and he opted for the former.

Outside the marble doors, at the courtyard before the Institute, a massive battle was taking place. Soaring through the cavern was a figure fully dressed in golden armor and wielding a blade of fire. Her wings drew streaks of white in the air, and her sword rained holy flames upon its owner's opponent. But even with her tremendous power, her efforts seemed to be ineffective.

At the cave floor, clambering up the steps of the Insititute, was a beast of gigantic proportions. Crooked, bony limbs and spines protruded from its curved back, and its leathery skin drank the flames hungrily. A pair of green eyes searched above for the golden figure. The monster unleashed a feral roar towards its target, who narrowly evaded. Instead, the stone ceiling exploded and fell, showering the courtyard with debris and dust. Several temors passed the cavern in succession as the monster fired soundwaves in an attempt to strike its prey.

Through heavy breaths, the golden figure muttered, "High Councilor, I can't keep this up much longer. The Voidborn will penetrate the doors any second now."

Heywan heard the voice through the blue gem of the ring around his finger and replied to it, "Just hold it back as long as you can. We're nearly done with the preparations. The summoners will be taking their positions now."

At the center of the circular chamber was a circle engraved into the floor. Serving as the focus, the circle would connect to the space of another world through advanced space-time thaumaturgy and hopefully allow a team of summoners to extract a hero from another world. It was an exhausting process and was not meant to be done so hastily, but they had little choice otherwise. Only one champion was available to deploy in the defense of the League; by the time the champions from the city-states would arrive, the Institute would a little less than rubble. They needed assistance, and they needed it now.

"Summoners, open the gate!" came the command.

Five summoners stood around the circle at specific points and began directing their energies into the focus. The air in the room seemed to swirl about. Heywan gritted his teeth.

The ground seemed to split and widen as the circle activated.

"Extraction team, begin the retrieval!"

Several hooded figures added their energies into the circle. Immediately their bodies tensed as they strained their concentration. They needed to find him, the one whom was shown to be the perfect candidate for defending the Institute from the Voidborn. Tense minutes passed as the extraction team searched for their target among the many.

The golden figure's voice erupted from Heywan's ring once again, this time with an urgent tone. "H-Heywan, the Voidborn is no longer engaging! It rammed through the doors and is headed to your location! Get out of here! I can't―!"

"Kayle! Are you alright? Respond!"

Before he could get an answer, the wall exploded, and the creature charged into the chamber, its maw snapping excitedly. Despite the scale of the assault Kayle had battered it with, its skin showed no signs of damage. The same figure was locked in the monster's limbs, her helmet lost sometime during her fight with the Voidborn. She tried to wrench herself free with her sword, but to no avail. Her blue eyes turned to the Councilor.

She screamed, "Get out of here! It's target is you!"

With a wild screech, the Voidborn moved. It was three times the size of any person in the room, and each step caused the floor to shake. The lights rolled off and shattered at the violent motion. With one last burst of strength, Kayle struck the beast with her burning sword.

It roared and hurled her across the chamber.

Then appeared a figure in red at the center of the ritual. He quickly caught the armored form and set her down. With wonder, she looked up at him as his brown eyes locked onto the monster.

"――I am the bone of my sword," she heard him whisper.

Before her eyes, a pair of curved swords, black and white, materialized in his hands. They seemed bulky and awkward, but he did not mind when he gave them an expert twirl. The creature, although rampant, seemed to regard the man as a threat and turned its full attention to him. It opened its jaw to unleash a blast of sound, but its target became a blur and charged.

The white sword found its target first. It pierced the skin of the Voidborn as if cutting paper, and a spray of green ichor splattered onto the marble. Its dark twin shot forward next, effortlessly slicing the leathery hide and shedding more of the creature's blood. Without hesitation, the red swordsman attacked again and again with his blades, even as the creature thrashed about and tried to fight back. He merely cut off its limb, or a spine, or even its jaw when it came close.

White and black danced before him, and soon the Voidborn fell dead; deep cuts gouged into its head; its many limbs and spines littered the rubble around it; its neck was fully severed from the torso. The man lowered his weapons and observed his surroundings.

"Hard to believe there would be another War," he said before his eyes fell onto Heywan, who had fallen onto the floor beside the corpse, speechless.

What light shined upon the room highlighted his figure; a tall, lean male with tanned skin and white hair swept back into spikes. He wore a sleeved cloak that hung only twenty or so centimeters off the ground held together with black leather armor. The swords disappeared, and he crossed his arms before his chest. He then spoke with a deep voice.

"I am Servant Archer, called forth from the Throne of Heroes. I ask, are you my Master?"
