Background: A lone surviving Spartan is secretly sent off of Reach during its invasion in the year 2552. When a Covenant Carrier exits slipspace while the Spartan's pod enters its own slipspace, the pod is sent into an anomaly sending him over 150 years into the future. What only would be a matter of seconds, the pod carrying the lone Spartan exits slipspace over a not-so familiar Earth. Humanity is now in "The Second Age"*. The world is a far more different place than it had once been. Now, the Spartan must grow accustomed to his new surroundings, customs, and a whole new world.
*"The Second Age" would be a period after Humanity died out. Humans then slowly repopulated the Earth; leaving scare old-world tech behind. Only few know of Man-kind's previous existence.
Spartan: The Recrudescence
Prologue: Part 1
The Pod exited the slipspace portal hurling towards the nearby familiar planet.
"Three-One Thousand, Two-One Thousand, One-One Thousand. Now entering Earth's atmosphere; please remain calm. Impact at Grid Point 322 – 0C in five, four, three, two, one; impact."
The pod, enveloped in flames, plowed through the dense tree-line and impacted the ground. It rolled forcefully through the dense forest underbrush and into a shallow swamp; the deep muck slowing the pod to a halt. Water quickly cooled it as steam rose from it.
"Landing successful," said a voice inside the pod. "Now testing vitals on Kai-A019." The lone figure in the chamber jolted awake; his head searing with pain and his stomach churning. He kicked the safety bolt holding the cryo chamber door sealed. The seams hissed and cold air streamed into the interior as the door slowly lifted.
He pitched forward and collapsed out of the chamber; his armor clanged against the titanium-A battleplate pod structure. "Please remain seated; an ONI Representative will tend to you shortly."
Seconds passed and the voice repeated, "Please remain seated; an ONI Representative will tend t— "; the man's fist crushed the speaker panel. "Remain seated my ass."
Prologue: Part 2
The Hokage looked out of his office window, up at the object streaming into the atmosphere. An attack on the village he thought? It couldn't be; the chakra signature from it was low. Could it have been a diversion?
Three ANBU appeared in front of his desk. "Sir, you called?" stated one of the masked ninja. "It appears we have an unexpected visitor. I want you three with me," said the Third.
"Sir, let us go survey the situation before you go—. " Sarutobi interrupted, "No. I would like to see this; I am more than capable of protecting myself if necessary. Let's move." The four ninja disappeared.
