Background
"A science fiction icon and winner of the field’s highest awards, Greg Bear has signed on to write three Halo novels set in the time of the Forerunners, the creators and builders of the Halos. Almost nothing is known for sure about this ancient race. Worshiped by the Covenant as gods, their engineering relics pepper the galaxy, and their connections to humanity remains unanswered. Devoted fans of both the books and games will finally get to delve deep into the era of these enigmatic beings, and discover for themselves the epic story behind one of the great mysteries of the Halo universe: the complete disappearance of the Forerunners from existence. World publication rights to Tor Books."

"It's going to be a trilogy. A connected universe that will remain faithful to the scale and mysteries, while exploring the detail and challenges of a VERY powerful culture. This won't be some skirt-raising exercise in Forerunner populist-ism. Folks know way more about Forerunners than you think, but we're definitely going to respect that strange sense of wonder and awe that Bungie infused from day one. It will be BIG Greg Bear fiction in a faintly familiar place, but one that's full of surprises. Think Eon."

- Frank O'Connor

Originally known only as the "Forerunner Trilogy", the series was officially announced at the Emerald City ComiCon in Seattle, Washington, where its author, Greg Bear, made a guest appearance. The first book's working title was "Antediluvian". The word "antediluvian" means, "of or belonging to the period before a flood," hinting that the novel takes place prior to the Forerunner-Flood War. The series reveals a great deal of new information about the Forerunner-human interactions in ancient history. On October 11, 2010, the official name of the book was revealed to be Halo: Cryptum.

During the writing process artists such as Sparth of 343 Industries created several illustrations for Halo: Cryptum. Frank O'Connor has mentioned that these illustrations will eventually be released in an art book.

Synopsis
Set during the golden age of the Forerunners, the series touches on the origins of humanity and the contacts with Forerunners and humans, as well as explaining the connection between the two and humanity's status as "Reclaimers". Forerunner technologies are explored in detail, and many new elements about the Forerunners are introduced, such as their political system and social structure. The characters of the Didact and the Librarian, introduced in the Terminals in Halo 3, are featured as central characters in the series.

Cryptum
Released January 4, 2011, Cryptum focuses on a young Forerunner known as Bornstellar Makes Eternal Lasting, a rebellious Manipular from a family of Builders, the highest and most politically powerful rate of the Forerunner. However, instead of following in his father's footsteps and becoming a Builder, Bornstellar is obsessed with exploring artifacts left behind by the Precursors, an enigmatic galactic civilization that preceded the Forerunner. His father sends him to the planet Edom in a distant system known as Sol to work with the Miners to come to terms with his duty as a Builder. Eventually, Bornstellar crosses paths with two humans on Earth, forever changing the fate of the galaxy.

Primordium
The sequel to Halo: Cryptum was released on January 3, 2012. Primordium is centered around Chakas, one of the two humans who accompanied Bornstellar in the first novel. After being captured by the Master Builder during the events of Cryptum, Chakas finds himself marooned on an embattled Halo installation, where he is joined by two humans on a quest to find his companion Riser. During their journey and its eventual conclusion, revelations are made as to the nature of the Flood, the rampant AI Mendicant Bias and the mysterious Captive, as well as the far-reaching plans of the Precursors.
