'''Keeper-of-Tools''' was a [[Forerunner]] [[Builder]].

==Biography==
===Path Kethona===
Keeper was part of the [[Librarian]]'s crew during the expedition to [[Path Kethona]] around [[98,395 BCE]]. He was a young, ambitious Builder who was being groomed to move high in Forerunner society; this was suspected to be the reason he was chosen to be part of the crew of the ''[[Audacity]]''. He devoutly attended the clandestine rituals of Builder secret societies, though he was still in the earlier phases of induction into their secrets.<ref>'''Halo: Silentium''', ''page 119''</ref>

After the first slipspace jump toward Path Kethona he noted that they had gone farther than any other [[Forerunner]] and praised the ''Audacity''.<ref>'''Halo: Silentium''', ''String 4''</ref> He reacted to the presence of ancient Forerunner and [[Precursor]] artifacts within Path Kethona with great enthusiasm, taking this as evidence of cooperation between the two millions of years earlier.<ref>'''Halo: Silentium''', ''page 115''</ref>

Keeper-of-Tools did not accompany the Librarian planetside after the crew discovered a world home to [[Path Kethona Forerunner|primitive Forerunners]] who had been isolated from their brethren in the [[Milky Way]] for ten million years. After the Librarian had found out the truth of the origins of the local Forerunners, ''Audacity'' and her crew returned to the [[ecumene]], although the Librarian would not reveal what she had discovered until much later.<ref>'''Halo: Silentium''', ''page 181''</ref>

===Work on Bastion===
Following the ''[[Audacity]]'s'' return, Keeper works with [[Birth-to-Light]], [[Dawn-over-Fields]] and [[Clearance-of-Old-Forests]] on [[Bastion]] to recreate the [[Precursor]]s, building the ''[[Eden (spaceship)|Eden]]'' to transport the seeds of the race outside of the galaxy when the time is right.<ref>'''[[Halo: Point of Light]]'''</ref>

===Upload to the Domain===
In the final days of the [[Forerunner-Flood war]], Keeper, Birth, Dawn and Clearance were sent to to be the caretakers of Bastion, but the Flood's advancement through Forerunner space changed things. The four Forerunners are waylaid time after time, cast into one battle after another and constantly evading capture. Knowing that their work on Bastion was too dangerous to fall into Flood hands, the four upload their essences into the [[Domain]] until the war is over and the way to Bastion can be achieved in secrecy and safety. 

To enact this, Keeper sought the help of an [[ancilla]] to procure a [[durance]] for him<ref name="Intel Reunion">'''Halo 5: Guardians''', ''campaign level [[Reunion]]'' - [[Mission Intel]]</ref>, which would allow the uploading of his mind to the Domain. However, the firing of the [[Halo Array]] nearly destroys the Domain, trapping and separating the four and possibly destroying the imprints of Birth, Dawn and Clearance.<ref name="POL294">'''[[Halo: Point of Light]]''', ''pages 294''</ref>

===Genesis===
After the Domain is accessed by [[Cortana]] on [[Genesis]], Keeper awakened and emerged on the planet to discover that it had been compromised and that a thousand centuries had passed.{{Ref/Reuse|POL294}} He discovered that Bastion had been moved from its original location, a feat he believed would require "an impossible act of reconciliation" to perform.{{Ref/Reuse|Intel Reunion}} Keeper eventually surmises that the [[shield world]]'s safety measures had been activated at some point in the past.{{Ref/Reuse|POL294}} He eventually found out that the Domain had been severely damaged by the Array, and was trapped on Genesis, degrading over time.<ref name="Intel Genesis">'''Halo 5: Guardians''', ''campaign level [[Genesis (level)|Genesis]]'' - [[Mission Intel]]</ref>

Surviving in Genesis' systems, Keeper witnessed the beginning of the alliance between [[Cortana]] and the [[Warden Eternal]], and reacted with alarm as they took control of [[Guardian]]s across the galaxy to enforce the [[Mantle of Responsibility]].<ref name="Intel Breaking">'''Halo 5: Guardians''', ''campaign level [[The Breaking]]'' - [[Mission Intel]]</ref> He noted, however, that the Domain had repaired itself enough to cure Cortana of her rampancy, and hoped to finally access it.{{Ref/Reuse|Intel Breaking}} Eventually, Cortana noticed his presence in her network and began to hunt him down, though Keeper left audio logs scattered across Genesis to warn the [[Blue Team|human]] [[Fireteam Osiris|forces]] who opposed her, noting that Cortana had not yet taken control of the installation's [[Constructor]]s, and that the installation's monitor, [[Exuberant Witness]], could use them to take back control.{{Ref/Reuse|Intel Breaking}}

As Cortana began to deploy her massed Guardian forces across the galaxy, and the Warden was distracted fighting both Blue Team and Fireteam Osiris, Keeper was able to finally access the Domain, restoring him and finally allowing him to locate Bastion.<ref name="Intel Guardians">'''Halo 5: Guardians''', ''campaign level [[Guardians]]'' - [[Mission Intel]]</ref>

===Bastion===
As the [[Created conflict]] begins, Keeper is finally able to transmit his consciousness into a [[monitor]] body on [[Bastion]] after the arrival of [[Rion Forge]] and [[343 Guilty Spark]] momentarily opens the shields and broadcasts a signal that Keeper is able to lock onto. Keeper calls Spark's choice of an [[armiger]] body "unfortunate" and states that they must move Bastion before his signal can be followed by a [[Guardian Custode|Guardian]]. Spark reveals [[Cortana]]'s uprising to Rion, explaining that he had been detecting signals for weeks that he only now understood was a call to arms for the Guardians.

Keeper leads the others onto a gondola heading for the Nursery and declares that he and Spark are quite similar as both of their eyes have been closed only to open a thousand centuries later with much having been lost. Spark recognizes Keeper's loss and realizes that he is a direct imprint or essence of the real Keeper-of-Tools and Keeper explains his story to Spark.<ref>'''[[Halo: Point of Light]]''', ''pages 289-294''</ref>

===''Eden''===
Keeper leads Rion and Spark to ''[[Eden (spaceship)|Eden]]'' a starship that he had built modeled after the ''[[Audacity]]'' in the Nursery. Reaching the bridge, Keeper explains that the ship was meant to carry an extraordinary payload at the Librarian's bequest when the time came. Keeper refuses to answer what ''Eden's'' purpose is, stating that it is not for him to say and he needs Rion's key to initiate the launch as ''Eden's'' departure is long overdue and Keeper must complete his mission.

As Rion and Keeper start the launch sequence, Keeper communicates with Spark inside of his head, stating that he doesn't trust the human. Although Spark points out that Rion was led there like him, passing the [[Precept]]'s test, Keeper calls it a last resort since the key was originally supposed to have been brought by the Librarian herself. Keeper suggests that the Librarian had planned for this as one of many possibilities, speaking of the Librarian as though she is not gone. However, Spark recognizes that Keeper is not accustomed to this new reality in which the Librarian no longer exists.

Keeper then explains that Bastion has need of an ancilla, having always been intended to be administered by three complete and unique ancillas like Spark. However, the monitors that had greeted Spark and Rion upon arrival are only indirect copies of the ''Audacity's'' crew and could potentially be swayed by Cortana which would be dangerous given that Bastion is the Librarian's laboratory containing her most dangerous research and experiments and Keeper believes that Spark had good reason not to be swayed by Cortana's promises.

As the ship's reaction drives come online, Spark questions where Keeper will go and if he will come back. Keeper states that he will go beyond this galaxy and has nothing and no one to return to. Keeper programs the gondola to take Rion and Spark back to the tower, having already sent his key there to give Spark control over Bastion. Addressing Spark as Monitor Chakas, Keeper states that he knows more about Spark than he knows and welcomes Spark home. Keeper gratefully returns the Librarian's key to Rion and Spark asks ''Eden's'' purpose is. After a moment, Keeper simply states "atonement" before departing the galaxy with ''Eden''.<ref>'''[[Halo: Point of Light]]''', ''pages 295-299''</ref>
