Prologue:
Millions of light years away in a distant galaxy, a world flourished with an advanced society. Peace was ideal and it would remain so for another millennia. However, one man looked down upon the people with spurning hatred. He was once one of them. He did not want peace, nor to uphold peace. He desired to conquer neighboring worlds, expanding his world and bend to his species' will. His people disregarded him as a nonsensical, power-hungry radical and chased him away. He ran until he stopped at a cliff. He was a wanted man by his people. He wanted his ideals upheld, but he realized the crowd would not tolerate his politics. Seeing no way out of that predicament, he jumped to his demise.
The public went back to their business, forgetting about the radical. Below the cliffs was a stygian ocean that reeked of rotten corpses rising from seething tar. The tar clung on and ate his body away. Through agony, the man lost his old identity. Every cell in his body flashed between life and death every second! When he traipsed onto the black, gravelly beach, he drew his first breath and a strange force reinvigorated his body. He rechristened himself… Tartarus! He held on to his old belief that his kin was capable of conquering worlds. Now it is only for himself! He sought to punish and eradicate his former kin. He ran and in a single bound jump, he flew towards the harbor's tallest building. He looked down with animosity in his eyes. His right arm ached at first, and the burning feeling shot into his fingers. They became scaled and fused with one another. His right hand enlarged, mutating into a draconic limb. Red eyes opened and glimmered! With this new power, Tartarus blasted a widespread energy wave, ravaging numerous skyscrapers! He flew down to vociferate his belief that his kin would conquer galaxies.
"However," he said. "I will be the one to write history. Your only assistance is your blood!" The military swarmed in on him. It never mattered how many bullets per nanosecond, or how many times a proton-charged particle beam had been fired, or how many soldiers were lost, the military's strength was proven no match to Tartarus's power. The general called for a last resort: withdraw the seven elite guards. These unknown men and women are given the responsibility to carry these crystals. Jewelry blessed by their ancestors' knowledge how to harness the following elements: Earth, Fire, Wood, Water, Wind, Darkness, and Light.
Tartarus flew higher into the stratosphere, and focused his essence to destroy his former home world. The warriors donned their ancestral crystals and prepared to battle Tartarus! The leader blasted a fiery beam that followed Tartarus around until it struck him, burning him. The second in command grabbed a passing meteorite and crushed it with his bare hands, and threw the pellets in the demon's face. Tartarus regained himself and rockets in the leader's direction. The armored woman cultivated vines from her cyber-organic arm and caught him by the ankles. She swung him around to the tall nomad. He breathed deeply and froze himself. Unfortunately, Tartarus saw the plan through and slammed the armored woman and nomad together. The old veteran vanished. With great stealth, he snuck behind Tartarus and held him in place. The old veteran's strength was no match to Tartarus as he threw him at the radical's first-born son. Tartarus smirks and charges towards him. The second-born son shined brighter than the world's sun and blasts the demon! It seemed that victory was assured for the Elite Soldiers, but Tartarus had a quickly healed himself, showing signs of minimum damage. With no other option, they mustered their final strengths and sealed the monster inside a spectrum sphere. With one final heave, they shoved him as far as possible from their planet.
"I only wish that it didn't have to happen this way," the armored woman said.
"Brother Typhon!" the second-born son said.
"Brother Helios! Sister Selene! We've done well. But at what cost?" said the first-born.
"I cannot feel… my legs anymore," the old veteran said.
"Look at ourselves!" the nomad shouted.
"As the prophecy was told by our forefathers," the second-in-command said.
"My only fear… is that it is not the end," said the leader.
The elite guards' bodies faded into energy and swept into the inside of the crystals and jettisoned the same way!
