A Keystone is a Forerunner artifact that holds Forerunner information.[1]
Overview
At least one keystone was buried on the planet Madrigal[1] with another keystone that went together with it on Eridanus II.[2] The keystone could display a holographic Forerunner script which led to at least one Halo ring.[3] Furthermore, the keystone has shown the ability to mass EMP and repower UNSC equipment. When touched, the Keystone is able to scan the person who touches it,[1] and awakened locked memories in John-117.[3][2] However, each time that John used the keystone it placed a strain on his heart and nervous system.[2]
When the Madrigal keystone was activated and John was put into stasis by Cortana so that the AI could access it herself, the artifact immediately shut itself down, seemingly needing John to be conscious to work. Later, after removing his emotional regulator, John realized that his altered hormonal state might've been affecting his interactions with the keystone. Following the regulator's removal and the restoration of a normal hormonal state, John's unlocked memories became clearer to him and easier to understand.[2]
Doctor Catherine Halsey suggested that the Madrigal keystone had its own intelligence given the way that it seemed to either respond to John's needs or anticipate what the situation required when he activated it.[4]
History
Madrigal Keystone
In 2552, the Covenant launched an attack on Madrigal for the keystone, wiping out a nearby Insurrectionist outpost. The Spartans of Silver Team eliminated the attacking Sangheili and John-117 and Kai-125 entered the cave where the Covenant had been excavating for the artifact. Upon finding the keystone, John touched it and the artifact reacted to the touch of a Reclaimer, lighting up the entire cave and displaying symbols. It had a surprising effect on John, apparently unlocking some of his sealed memories of his childhood. The artifact's reaction to John was noticed by a surviving Sangheili who managed to escape and report it back to the Prophet of Mercy who had learned of the artifact's location from Makee.[1]
Throughout his return trip to Reach, John remained fascinated by the artifact while Dr. Catherine Halsey became concerned about its effects on John and his memories. After John rebelled rather than execute Kwan Ha, the UNSC shot down his Condor with an electromagnetic pulse, knocking the artifact loose from its casing in the process. John touched it, causing the symbols to display once again and for John to experience more of his memories. In one of his memories, a young John drew a picture of the artifact for his mother. The artifact then let out a pulse that knocked out power to the UNSC base while restoring power to John's Condor, allowing John to escape from Reach with Kwan and the artifact.[1]
John subsequently took the keystone to the Rubble to seek out Soren's help. Soren's touch failed to elicit a reaction from the keystone and he introduced John to Reth, a man who had been on one of the Covenant ships and had been tested as a Reclaimer. Like with Soren, the artifact also failed to respond to Reth. When Reth shoved the keystone into John's hand, it triggered a pulse that caused everyone but John great pain and for the symbols to display once again as well as causing John to see more of his childhood memories. John quickly returned the keystone to its box, ending the effects. Reth explained that the ring that it had displayed when activated was what the Covenant and a door to the end of life as they knew it. Reth confirmed that the ring was a weapon and after John admitted that he could feel the darkness, Reth urged John to destroy the keystone and then himself. However, John then decided to take the artifact back to the UNSC where it was studied by Halsey who described it as being nothing like she'd ever seen before.[3]
At the same time, on High Charity, Makee and the three Covenant Hierarchs listened to the surviving Sangheili warrior's testimony about what he had seen. Alarmed that the Demon had gotten his hands on one of the keystones, Makee decided to pursue it herself.[3] Makee attacked the UNSC Gladius with the help of a Lekgolo colony, but they failed to get any information from either the crew or the ship's database which was wiped during the attack as per the Cole Protocol.[2]
Admiral Margaret Parangosky later told Miranda Keyes that results confirmed that the keystone was over 100,000 years old which Miranda was stunned by, calling it pre-human and possibly even pre-Covenant. Miranda noted that the keystone was organic, but with what appeared to be an inherent technology. Parangosky revealed what John had learned about it leading to a weapon somewhere and asked Miranda to lead a team analyzing the artifact to determine what it was, what it did, if it was in fact a part of some kind of a weapon or anything that could give humanity an edge over the Covenant. Parangosky sought to create parallel teams studying in the artifact in order to find a way to be less reliant on Halsey in the future.[2]
Under monitoring by Halsey and Adun Saly, John activated the keystone once again, triggering more of his childhood memories featuring a young John drawing and exploring a glowing cavern. As John reached for something in the memory, Halsey had Cortana put John into stasis so as to have Cortana access the artifact herself. However, as soon as Cortana shut John down, the keystone deactivated itself and Cortana got no readings from it at all. Halsey had Cortana release John who called this experience with the artifact "different" than the previous times. With Cortana's help, John later attempted to locate the planet from his memories using the FLEETCOM Central Database.[2]
After removing his emotional regulator and having an epiphany after seeing a dog in the park, John returned to the artifact and had Cortana, with Halsey's consent, override the lock on the room's door. Despite Cortana's warnings that touching the keystone put a strain on his heart and nervous system each time, John activated it once again and unlocked more of his childhood memories which revealed that he drew both the Madrigal keystone and another larger one, showing his mother that the two artifacts went together and that John's father had eventually forced him to bury something against his will. With the added information from his newly-unlocked memories, John identified the planet that the second keystone was on as Eridanus II. John subsequently explained to Halsey that John had realized that his altered hormonal state from the regulator had been messing with his interactions with the keystone.[2]
While John and Halsey were away searching for the Eridanus II keystone, Keyes tested the Madrigal keystone on Silver Team, but it failed to react to any of the other Spartans. After discovering that the Spartans knew some of the Sangheili language in the process, Keyes enlisted Kai-125's help to translate Makee's message to her ship following the attack on the Gladius. The two translated the word "keystone" which they realized likely meant the artifact and accessed the recording of John first activating the keystone. Keyes and Kai realized that the ring displayed on the activated keystone was the Sacred Ring or Halo that Makee was talking about. Kai agreed to Keyes' request to keep their discovery hidden until Keyes could figure out what it all meant.[4]
Eridanus II Keystone
A second, much larger, keystone existed on Eridanus II, one that went with the Madrigal keystone. It was discovered by John-117 as a child while exploring outside of the Reach for Life installation during a family picnic. When John discovered the keystone, he touched it and the cavern briefly shook before John ran away again.[4] As a result of his experience, John began to repeatedly draw both the Eridanus keystone and the Madrigal one, recognizing that they went together. Eventually, John's father grew frustrated and forced John to bury his drawings of the keystones outside of his home.[2]
In 2552, after the adult John touched the Madrigal keystone, his blocked childhood memories surrounding the Eridanus keystone started to be unlocked.[1][3] John eventually remembered that there was a second artifact on his home planet and located the correct world with Cortana's help, although Eridanus II was uninhabited by this point and sealed off, most of the population having been wiped out by a plague. John decided to return to Eridanus II in search of the keystone and Dr. Catherine Halsey insisted upon going with him. Cortana was able to generate a holographic image of the Eridanus keystone based on John's description for Halsey and Adun Saly.[2]
Outside of his childhood home, John dug up the box containing his drawings of both keystones. With Cortana's help, John recreated his ruined home, triggering John's memories of finding the artifact as a child. John was then able to use his restored memories to locate the cavern once again where John and Halsey found the keystone.[4]
The UNSC subsequently had trouble removing the keystone from the rock, causing Halsey to set up a camp nearby and bring in more UNSC personnel to help with the problem. As Halsey and her team struggled to remove the keystone from the rock, Cortana appeared to the watching John and told him that an analysis of its field physics suggested that the energy that it could produce was much stronger than that of the Madrigal keystone which wasn't surprising given its size. However, John didn't respond to her and Cortana watched as Halsey told John that it was a serious safety issue for him and for others and she wanted him to stay away from it until she ran some more tests. While Halsey and Adun Saly studied the artifact, Riz-028 readied the UNSC forces for their mission to get it onboard the UNSC Pioneer before the Covenant could figure out that they were on the planet.[5]
As Saly used a laser to try to get through the crystal protecting the keystone, it suddenly let out a massive energy pulse that created a shockwave on the planet's surface and was picked up by the Covenant Luminaries on Madrigal, allowing Makee to see where it was. As John reentered the cavern, the crystal coating around the keystone shattered, leaving the artifact exposed. Studying the readings on the signal, Miranda Keyes determined that the keystone had been communicating with something and theorized that, rather being two halves of the same weapon, it was some other kind of device altogether.[5]
Shortly thereafter, seeking answers about his past, John touched the keystone against Cortana's warnings that it could kill him. Reacting to John's touch, the keystone lit up with symbols, recognized him as a Reclaimer and caused John to remember touching it as a child and his kidnapping by Halsey and being replaced by a clone. The brief contact with the artifact put a strain on John's body and caused him to briefly collapse.[5]
Shortly thereafter, the Covenant attacked in search of the artifact. With the UNSC Pioneer destroyed and the other ships too big to get into the canyon, Silver Team were ordered to deliver the keystone to Miranda's ship and then to the Endymion II after the Condor was destroyed. However, after Kai-125 was injured and surrounded, John abandoned the mission to go to her rescue and Silver Team's Warthog was hit by a crashing Banshee, flinging the keystone loose and causing it to hover. Atriox emerged from Spirit dropship, took the keystone and successfully escaped with it to a nearby CCS-class battlecruiser.[5]
Production notes
The Madrigal Keystone uses a form of Forerunner symbols featured in the core canon, with the relic in Contact saying "Scan - End".[1]
