I guess I should probably say this, cause I don't want to get sued: 343i and Microsoft Studios own Halo, while the Walt Disney Corporation and Lucasfilms own Star Wars. Hopefully I'm not forgetting any legal simpery, and without further ado, let the story resume!
9th Age of Reclamation
"Noble prophets of Truth and Mercy," the Bute said as he knelt, his hand in a fist on his chest. "I have brought the incompetent."
"You may leave, Tartarus," Truth said with a dismissive wave of his hand.
"But… I thought-"
"And take your Brutes with you," Truth finished.
"Release the prisoner," Tartarus ordered his men. Without hesitation, they let go of their cargo, a shamed, branded Elite, and walked out, knowing to listen to their hierarchs.
"The council decided to have you hung by your entrails and your corpse paraded through the city," Truth stated. "But ultimately, the terms of your execution are up to me."
"I am already dead," the Elite explained, covering the brand on his chest.
"Indeed. Do you know where we are?" Truth replied.
"The Mausoleum of the Arbiter," the Elite answered.
"Quite so. Here rests the vanguard of the Great Journey," Truth said, his head slowly moving away from the shamed warrior up to the many caskets embedded in the walls. "Every Arbiter, from first to last, each one created and consumed in times of extraordinary crisis."
"The Taming of the Hunters, the Grunt Rebellion, the Human War! Were it not for the Arbiters, the Covenant would have broken long ago!" The Prophet of Mercy shouted in a tone that blurred the line between rage and zeal.
"Even on my knees, I do not belong in their presence," the Elite said, refusing to do anything but look at the floor he faced.
"Halo's destruction was your error, and you rightly bear its blame," Truth bored into the Elite. "But the council was… overzealous. We know you are no heretic. This is the true face of heresy," he explained. Silently, he tapped a button on his chair and a hologram of a tall, elderly human appeared. It opened its mouth and spoke silently, the translation following almost imperceptibly after.
"Hello oppressed citizens of a once free galaxy. I am Count Dooku of Serreno. For my entire life, I served as a Jedi knight, and for many years, on the Jedi High Council. I dedicated my life to peace and justice, undertaking countless missions and risking my life countless times. I have protected people and communities, and brought countless criminals, pirates, terrorists, tyrants, and corrupt individuals to justice. And yet, as a Jedi, I was serving the most corrupt, most destructive institution in the entire galaxy," it spoke.
The hologram moved to speak again, only to be turned off by Truth.
"Very few know, but an expansion fleet has breached the slipspace anomaly. Beyond it lies the rest of the galaxy, a galaxy dominated by humans, a galaxy at war with itself, a galaxy weakened, a galaxy of heresy. That heretic, that 'Count Dooku,' leads one the most powerful factions of the galaxy, a group of secessionists that use an army of thinking machines to fight their wars. An army of heresy. He must be silenced," Truth explained.
"Its slander offends all that walks the path!" Regret cried.
"What use am I? I can no longer command ships, lead troops into battle." The Elite lamented.
"Not as you are, no. But become the Arbiter...and you shall be set loose against this heresy with our blessing," Truth said, a hint of mischief and joy mixed into his otherwise sinister tone. As he finished, he pressed a button on his chair and a large pod gently floated forward. Its base folding out as a walkway.
"What of the council?" The Elite asked, already knowing the response.
"The tasks you must undertake as the Arbiter are perilous, suicidal. You will die, as each Arbiter has before you. The Council will have their corpse," Regret stated, just as the Elite knew he would.
The Elite, the Arbiter, rose and stepped onto the platform as it opened, revealing the legendary armor that every Elite was awed by and terrified of. He knew his destiny now. He took the helmet, examined its intricate carvings, and set it upon his head.
"What would you have your Arbiter do?"
