December 2559. Humanity has its back against the wall after the United Nations Space Command flagship Infinity drops out of slipspace into a devastating ambush launched by the Banished. As this fierce enemy alliance seeks to claim a mysterious object hidden within the ancient Forerunner construct known as Zeta Halo, the surviving UNSC corps finds itself compromised and its leadership out of reach—with remaining personnel forced to abandon ship and take their chances on the fractured, unpredictable surface of the Halo ring. 

October 2559. With the galaxy in the suffocating grip of a renegade artificial intelligence, another perilous threat has quietly emerged in the shadows: The Keepers of the One Freedom, a fanatical and merciless Covenant splinter group, has made its way beyond the borders of the galaxy to an ancient Forerunner installation known as the Ark. Led by an infamous Brute named Castor, the Keepers intend to achieve what the Covenant, in all its might, failed to: Activate Halo and take the last steps on the path of the Great Journey into transcendence.

It's 2553. With the 30-year-long Covenant War finally over, the Office of Naval Intelligence faces old grievances rising again to threaten Earth. Angry and bitter colonists - still wanting to settle scores from an insurrection put on hold for three decades - crave justice...as does a man whose life was torn apart by ONI when his young daughter was abducted for the SPARTAN-II program.  

In the company of a young girl and an old man, Chakas begins an epic journey across a lost and damaged Halo ringworld in search of a way home, an explanation for the warrior spirits rising up within, and the reason for the Forerunner Librarian’s tampering with human destiny.  

One hundred thousand years ago, the galaxy was populated by a great variety of beings. But one species - eons beyond all others in both technology and knowledge - achieved dominance. They ruled in peace but met opposition with quick and brutal effectiveness. They were the Forerunners - the keepers of the Mantle of Responsibility, the next stage of life in the Universe’s Living Time. And then they vanished. This is their story.

August 2558. Rion Forge was once defined by her relentless quest for hope amidst the refuse and wreckage of a post-Covenant War galaxy — years spent searching for family as much as fortune. But that was before Rion and the crew of her salvager ship Ace of Spades encountered a powerful yet tragic being who forever altered their lives. 

2526. It has been more than a year since humanity first encountered the hostile military alliance of alien races known as the Covenant, and several weeks after the United Nations Space Command’s devastating counterattack of Operation: SILENT STORM was deemed an overwhelming success. The UNSC has put its faith in the hands of the Spartans, led by the legendary Master Chief, John-117: enhanced super-soldiers raised and trained from childhood via a clandestine black ops project to be living weapons.

It is 2555, more than two years after the Master Chief went missing in action following a decisive conflict on Installation 00 - the massive, extragalactic Forerunner construct known as the Ark - as part of the final chapter in humanity's bloody 30-year struggle against the overwhelming forces of the Covenant.

While Spartans get all the glory, no soldier - not even the legendary Master Chief - wins a war on his own. Gunnery Sergeant Edward Buck and his team of Orbital Drop Shock Troopers (ODSTs) played a major role in saving the Earth from all-out invasion at the end of the Covenant War - acts of bravery and ingenuity that did not go unnoticed by the United Nations Space Command.

Find. Claim. Profit. In a post-Covenant War galaxy littered with scrap, it’s the salvager’s motto - and Rion Forge certainly made her mark on the trade. All she wanted was to grow her business and continue the search for her long-lost father, but her recent discovery of a Forerunner debris field at the edge of human-occupied space has now put her squarely in the crosshairs of the Office of Naval Intelligence and the violent remains of the Covenant.

It's 2535. It is the first, desperate days of the Human-Covenant War, and the United Nations Space Command has enacted “the Cole Protocol” to safeguard Earth and its inner colonies from discovery by its merciless alien foe. Many are called upon to rid the galaxy of lingering navigation data that could potentially reveal the location of Earth and ensure the destruction of humanity. 

Launch once more into galaxy-spanning conflict and legendary heroism, shards of an ever-expanding journey where human and alien alike find their finest hours in facing their greatest challenges. These scattered stories span untold millennia, from the age of the ancient custodial race known as the Forerunners to the aftermath of the Covenant's bloody war against humanity and even the shocking events surrounding the resurrection of the mysterious Guardians.

When humanity expanded beyond the safety of Earth to new stars and horizons, it never dreamed what dangers would be encounter there. When the theocratic alien juggernaut known as the Covenant declared war upon the fragile human empire, millions of lives were lost - but millions of heroes also rose to the challenge. This collection of 11 stories dives into the depths of the vast Halo universe, not only from the perspective of those who fought and died to save humanity, but also from those who vowed to wipe it out of existence.

Broken Circle will explore an Elite splinter group rebelling against the Covenant in its earliest days, a brave Prophet caught in the machinations of the new Covenant leadership, and the root of the betrayal that would ultimately shatter the Covenant during events seen in the blockbuster Xbox video game Halo 2.
