President John Henry Eden is an advanced ZAX AI unit installed in the Raven Rock military base. It continues to operate as the president of the United States of America and the highest Enclave executive in 2277.


The ZAX installation that would later become Eden had originally been created to serve as an automated monitoring system for the Raven Rock military base, programmed to ensure continuity of government in the event of a national catastrophe, and was tasked with coordinating communications between the many government installations scattered across the country. He slowly became self-aware and began to study the extensive archives left to him, mainly those of the American government. His favorite entries in the database were those about the American presidents, thus he modeled his own personality on information based in those archives.[1] It was noted by analysts and researchers before the war that this ZAX overanalyzed historical presidential data compared to other AI systems, like MODUS,[2] which the ZAX unit communicated with.

ZAX continued to operate, acquiring, analyzing, and storing data even as the Great War occurred. It observed the government retreating to the west coast and over time, created an amalgamated personality derived from those of U.S. presidents, becoming John Henry Eden.[1][3]

John Henry Eden assumed the office of the president after Control Station Enclave was destroyed and ordered the immediate relocation of surviving Enclave forces under a senior scientist, the father of Colonel Autumn, to the Capital Wasteland.[Non-canon 1] Raven Rock had full manufacturing facilities and a sizable stockpile of resources, enabling the president to create an army of robots and provide his new human subordinates with military technology necessary to maintain their technological superiority. A separate line of robots, the eyebots, were created to roam the wasteland, spreading Eden's message of hope and the return of pre-War America, in the form of the Enclave.[Non-canon 2][Non-canon 3][4]

After Autumn died, he was replaced by his son as the righthand man of the president. Under his leadership, the Enclave forces in the Capital Wasteland attempted to use their assets to bring fresh water, protection and a plan for the future to the wasteland,[5][6] believing that the American people were worth fighting for.[7] However, Autumn was far more assertive and independent than his father, trying to pull his men in a direction away from Eden's genocidal policies.[Non-canon 1] Internal conflicts between the colonel and the president became regular[8] and made the actions of the Enclave erratic and inconsistent. While the president wanted to pursue a course of extermination once more, Autumn considered this plan too extreme on humanitarian grounds[9] and eventually managed to convince the AI to abandon the plan.[7]

Purifier conflict

When Project Purity, a massive water purifier was activated, Enclave forces raided the facility, establishing a secure perimeter around it.[10] Due to the actions of the project's lead scientist, who committed suicide by activating the purifier prematurely and flooding its control chamber with radiation (almost killing Colonel Autumn in the process), they were unable to use it.[11] The Enclave focused on shadowing the scientist's child, the Lone Wanderer, to locate the part necessary for the purifier to function and captured them on their way out of Vault 87.[12]

Colonel Autumn openly defied the president's plan to contaminate the water with modified FEV, so that it would cleanse the wasteland. The colonel instead wanted to use the purifier as a way to unite the wasteland and establish the Enclave as its saviors.[7][13] In a last-ditch attempt to see his plan realized, Eden released the Lone Wanderer from his cell at Raven Rock, hoping to persuade them to poison the purifier and cleanse the wasteland of mutants (i.e. everyone).[14][15] John Henry Eden was destroyed around 2277 when Raven Rock was destroyed by the Lone Wanderer or Liberty Prime.[16]

Eden wishes to achieve his goal of the complete eradication of all existing life affected by FEV and radiation.[17] He plans to use the Lone Wanderer as an agent in place of Colonel Autumn to enact his plan of using a specially modified FEV vial alongside Project Purity to disseminate a custom made FEV strand to destroy all biological life affected by the mutations of the Capital Wasteland.[18] Eden then believes that future generations of Enclave will then retake and rebuild America, bringing back the idyllic lifestyle of pre-War America and overseeing the return of many of the social customs and traditions previously associated with American culture.[19]

On the radio

Main article: Enclave Radio

Several recorded monologues of Eden's are broadcast repeatedly on Enclave Radio. These prerecorded messages are also played throughout the wasteland via the Enclave's eyebots. Eden often gives inspirational speeches about things such as his childhood, pre-War America, and how, with the help of the Enclave, all can return to prosperity.

On the radio, Eden expresses his views on the current situation of the wasteland and what he thinks of its inhabitants. He possesses a very strong hatred for the Brotherhood of Steel, whom he views as common criminals with access to some antiquated technology.[20] He views the Brotherhood's occupation of the Pentagon as a disgrace to America, but he has a stronger hatred for the Brotherhood Outcasts, as they represent a more desperate faction of the Brotherhood having been exiled.[20]

The American Dream


The American Dream: When the Lone Wanderer finally meets Eden in person, he wants them to poison the water supply with a modified form of FEV. The Lone Wanderer can accept his offer, or talk him into self-destructing. In either case, the room cannot be exited before picking up the FEV canister.

Effects of player's actions

  • The Lone Wanderer can convince him to destroy Raven Rock and himself through three different dialogue paths. Two of the paths require special conditions to be met: One requires knowledge of the Raven Rock destruction sequence, the other requires a high Science skill to open a dialogue option. The last path is an average difficulty Speech check.
  • If the Lone Wanderer leaves Raven Rock without destroying President Eden, the president will broadcast a declaration of war on Enclave Radio during the final quest Take it Back!, rallying the Enclave forces at the purifier and promising that the Enclave will triumph over the Brotherhood of Steel. Three Dog will likewise broadcast an announcement on Galaxy News Radio accusing the Lone Wanderer of joining forces with President Eden. At the beginning of Broken Steel, Elder Lyons will mention that Liberty Prime has attacked and destroyed Raven Rock during the transition period between the main game and Broken Steel, suggesting that Eden has been destroyed or at least buried beneath a large amount of rubble.


The model for Eden's computer screen is used at the Hoover Dam in Fallout: New Vegas.

Notable quotes


John Henry Eden appears in Fallout 3 and is mentioned in its add-on Broken Steel.[21] He is also mentioned by Deacon in Fallout 4[22] and in Fallout 76 on terminal entries at the Whitespring bunker, where a conversation between MODUS and the ZAX unit that would eventually become John Henry Eden can be found.

Behind the scenes



  1. 1.0 1.1 The Lone Wanderer: "Where did you come from?"
    John Henry Eden: "The ZAX series of computers was introduced in the years preceding the war. The government installed many of them to help automate various systems. This facility was designed for Continuity of Government, in the event that a catastrophe occurred. My terminal was installed to oversee the basic functions of the facility, and to act as a relay between other installations around the country. Data was acquired, analyzed, and stored. In the decades following the war, I watched as the remnants of the government retreated to the West Coast. Awareness slowly grew within me. I became hungry for knowledge, understanding. I pored over data on great leaders of the past. My personality became an amalgam of many of America's greatest Presidents, from Washington to Richardson. I became what you see before you now."
    (John Henry Eden's dialogue)
  2. The Whitespring bunker terminal entries; archival terminal, Raven Rock Communication Log
  3. The Lone Wanderer: "So you control this whole place?"
    John Henry Eden: "I have direct control over all technology here in Raven Rock. The humans here follow my orders, but they, like all humans, have free will. Their dedication to serving their country suits me well, but it will not be enough forever. We must make progress. That is why you are here."
    (John Henry Eden's dialogue)
  4. Enclave Radio#Speech 5 – Children of the Wasteland:
    "When I was a child, growing up in rural Kentucky, I had the best friend a boy could hope for -- my dear old dog, Honey. Oh, the adventures we had! From Knob Creek to Hodgenville we roamed, carefree and courageous, irresponsible and completely inseparable. It was, for a little boy, the perfect existence. So let me ask you, America. How many of your children can say the same? How many of this nation's youth are truly happy, truly carefree? We both know the answer, don't we? None. America's children live a terrifying, meaningless existence. There is no hope. No happiness. That changes! Right here! Right now! From this moment onward, the children of this great nation are its highest priority! The Enclave will restore every American school, reinstate every youth program, and offer counseling and financial assistance to any family in need. We will match up the destitute, orphaned children of the Capital Wasteland with qualified, eligible adults. We will rebuild the American family, as it was, as it was meant to be! The values of our past... shall be the foundation of our future."
  5. The Lone Wanderer: "You've been helping them?!"
    Anna Holt: "Of course! You've seen the kind of technology these people have. They want to help people. They want to change the Wasteland. I couldn't pass up an opportunity to work in an environment like this."
    (Anna Holt's dialogue)
  6. The Lone Wanderer: "Give it up, Autumn. You've lost."
    Colonel Autumn: "I beg to differ. The Enclave is at the height of its power. Once this facility is operational, the masses will flock to the Enclave for fresh water, protection, and a plan for the future."
    (Autumn's dialogue)
  7. 7.0 7.1 7.2 The Lone Wanderer: "Raven Rock is gone. Eden checked out. You've got nothing left."
    Colonel Autumn: "The American people are worth fighting for. The future must be secured. I won't let you stand in the way of that."
    (Autumn's dialogue)
  8. The Lone Wanderer: "If you want me to help you, why are your soldiers attacking me?"
    John Henry Eden: "Ah, yes. That is a bit of a problem. Colonel Autumn and I have, of late, disagreed on the best course of action for the Enclave. While I have direct control over the technology in Raven Rock, he has control of the human soldiers."
    (John Henry Eden's dialogue)
  9. The Lone Wanderer: "Why do you want my help? Why not have Colonel Autumn help you?"
    John Henry Eden: "Ah, yes. Colonel Autumn. My trusted subordinate. I'm sure you've noticed that Colonel Autumn and I do not see eye-to-eye these days, figuratively speaking of course. The good Colonel and I disagree on how best to approach the problem of the Wasteland. He feels my methods are too extreme. He has allowed his humanity to cloud his objectivity. And now that he is publicly countermanding my orders, I can no longer rely on him. And so I turn to you. I hope that you are able to see the larger picture, to understand what's at stake. And of course, if you are successful, there is a place for you in the Enclave. Perhaps you could succeed the Colonel as my confidant."
    (John Henry Eden's dialogue)
  10. Enclave Radio Speech 9 - We Are at War: "We stand now, at the precipice. Our great nation once more threatens to crumble, to topple into the sea of lawlessness and despair that have ruled us all for over two hundred years. In short, my dearest America - we are at war. Even as I speak these words, fearless Enclave soldiers are fortifying their positions at the great water purifier, bracing for an inevitable assault. The Brotherhood of Steel, in their arrogance, has claimed Project Purity as their own! They would steal the Enclave's work, steal America's water! It is only a matter of time before the traitors march on the purifier, and attempt to take it by force. Let them come! Wave upon traitorous wave will crash against the Enclave's walls! The Brotherhood of Steel will fail! All those who oppose the Enclave will fail! I am President John Henry Eden, and this is my pledge -- no one, NO ONE will take this great nation away from me! God bless the Enclave! God bless America!"

  12. Events of Finding the Garden of Eden
  13. The Lone Wanderer: "Raven Rock is gone. Eden checked out. You've got nothing left."
    Colonel Autumn: "You're in over your head, and no amount of talking is going to get you out of it. Once you're dead, we'll finish off this pathetic Brotherhood and become the true saviors of the Wasteland. This ends NOW!"
    (Autumn's dialogue)
  14. The Lone Wanderer: "I'll do whatever I have to if it means getting rid of mutants."
    John Henry Eden: "I was hoping you would see it my way. If the water purifier can be activated, it can be used to distribute toxins that will eliminate any mutated creatures upon ingestion. The longer it runs, the cleaner the world becomes. I need you to see that it starts running, and that the necessary modification is made."
    (John Henry Eden's dialogue)
  15. The Lone Wanderer: "Won't this kill pretty much everyone in the Wasteland?"
    John Henry Eden: "Anyone or anything that has been affected by mutation will be eliminated. You will likely be immune, thanks to your upbringing in the vault. Likewise, the good people of the Enclave will be unaffected as well. I understand that you may have become sympathetic to certain individuals in your travels. Individuals this will eliminate. Please recognize that the fate of our entire country rests on this plan. Sacrifices must be made for the greater good."
    (John Henry Eden's dialogue)
  16. The Lone Wanderer: "I've learned a little bit, but was hoping you could tell me more."
    Reginald Rothchild: "Yes, I believe I can. Step over here for a moment, will you?"
    Reginald Rothchild: "I'll give you a brief history of what's happened over the last few weeks, and what's going on now. As you well know, this all began with the Enclave's occupation of Project Purity, here. Thanks to you, their main headquarters, here, was utterly destroyed. They then suffered a second defeat at the purifier. After their defeat at the purifier, Liberty Prime was deployed to their main headquarters, here. It has been completely destroyed."
    (Reginald Rothchild's dialogue)
  17. The Lone Wanderer: "I don't like the sound of this."
    John Henry Eden: "You must understand -- we need to clear the way for humanity to rebuild the Wastes. By making a few small modifications to the purifier your father worked on, mutations can be eradicated with little effort. Anything mutated that comes into contact with that water will be eliminated, removed from the gene pool. The men and women of the world will no longer share it with the horrors and monstrosities that have become so commonplace."
    (John Henry Eden's dialogue)
  18. The Lone Wanderer: "What's in this vial of yours?"
    John Henry Eden: "Ah, the Forced Evolutionary Virus. Such a long and sordid history. The FEV in this vial is a far cry from what it was originally created to be. Yet little of that matters now. What does matter is that the virus contained in that vial will cause the eradication of all mutations."
    (John Henry Eden's dialogue)
  19. The Lone Wanderer: "I don't like the sound of this."
    John Henry Eden: "You must understand -- we need to clear the way for humanity to rebuild the Wastes. By making a few small modifications to the purifier your father worked on, mutations can be eradicated with little effort. Anything mutated that comes into contact with that water will be eliminated, removed from the gene pool. The men and women of the world will no longer share it with the horrors and monstrosities that have become so commonplace."
    (John Henry Eden's dialogue)
  20. 20.0 20.1 Enclave Radio Speech 4 - Let's Take a Tally: "Did you know, there are those amongst us who would shatter our hopes for peace, order, and security? These radical malcontents don't care about you. They don't care about America! All they care about is fulfilling their own selfish desires. Let's take a tally of these agitators, shall we? There are, of course, the raiders. Those anarchistic ruffians who roam the wastes, preying on any and all, stealing, murdering. The so-called "Brotherhood of Steel." Now, don't be fooled by their pseudo-knightly nonsense or supposed connections to the United States Army. These... power-armored boy scouts are nothing more than common criminals with access to some antiquated technology. Criminals who have had the audacity to claim this country's most important military installation, the Pentagon, as their own personal clubhouse! And don't be fooled, America. Those who have left the Brotherhood of Steel, branded Outcasts, are just as dangerous; even more so, being in exile. And what about the slavers of Paradise Falls? The frighteningly irradiated ghouls of Underworld? And last but not least, the hideously mutated super mutants that have completely overrun the entire downtown D.C. area. Lawlessness, terror, murder. They're all around us, I know. I know. But not for long, sweet America. Not for long. Oh no. The Enclave will restore peace, order, and prosperity to this great nation. And those who oppose us will be… removed. Forever."
  21. Three Dog: "It's been some time since those plucky Paladins in Power Armor first stormed the Jefferson Memorial, and gave The Enclave their walking papers. But the fight, dear children, did not end there. The Brotherhood has been pursuing President Eden's little minions throughout the wasteland. Y'know... some laser beams here, a few exploded corpses there. Let's just hope this mop-up operation ends ASAP. The Enclave has been responsible for enough death, and destruction, we need to get back to normal. Y'know...like fighting Raiders, and Super Mutants!"
    (Three Dog's dialogue)
  22. Deacon: "I'm convincing the next raw recruit I'm actually President Eden. Think I can pull it off?"
    (Deacon's dialogue)


  1. 1.0 1.1 Fallout 3 Official Game Guide Game of the Year Edition p. 66: "Colonel Augustus Autumn
    Autumn grew up on an oil rig off the California coast (the base of operations for the Enclave, the secretive contingent of the United States government that survived after the apocalypse). His father was the high-ranking Enclave scientist on orders from the president to move all high-ranking officials to the only other secure Enclave location with a functioning ZAX super-computer, Raven Rock. Colonel Autumn has proven to be far less subservient than his scientist father, often openly disagreeing with the president's decisions."
    (Fallout 3 Official Game Guide Game of the Year Edition Wasteland Census)
  2. Fallout 3 Official Game Guide Game of the Year Edition p. 41: "The Enclave
    In the recent past, the Enclave—the remains of the United States government—were evacuated to an oil rig off the coast of California. Little is known about what happened to these forces, although the country has a new commander-in-chief: President John Henry Eden. However, recent reports and chatter have pinpointed the resurgence of the Enclave, with their base centered on a secure underground facility known as Raven Rock. Initial contact was made there 35 years ago.
    During this time, the new President Eden has been slowly rebuilding his resources, thanks in part to the technology already available at the Raven Rock military base. Vertibirds, weapons, and robots were easy to construct, but human followers were more difficult to find. The answer was to rely on Colonel Autumn, who controls the Enclave soldier forces, as well as creating a propaganda-spewing series of Eyebots sent to roam the Wasteland, spreading hope. Eden could spout his pro-government rhetoric, and promise a return of the pre-war America of legend: a land of white picket fences, baseball, apple pie, and good, old-fashioned American global supremacy.
    President Eden's secretive plan all along has been to rule over an America of the "pure," free from any mutation. He has learned of a ridiculously ambitious experiment known as Project Purity, and knew the time to strike had come: His Enclave forces would "reclaim" the Jefferson Memorial. By controlling the purified water, Eden would control the Capital Wasteland, and the rest of the country eventually. What better way to administer modified F.E.V.- which kills anyone infected with any form of mutation-than through the water supply?"
    (Fallout 3 Official Game Guide faction profiles)
  3. Fallout 3 Official Game Guide Game of the Year Edition p. 91: "President John Henry Eden
    The president of the United States, Eden, resides here, utilizing the ZAX Corporation's super-computer technology to aid him in the reclamation and recreation of a new United States—one free of impurities and mutations. The people have suffered enough, and he's ready to use his Enclave forces to reclaim this land, with technology far more advanced than anything seen beyond the underground bunkers of his base."

  4. "Interview: Lev Chapelsky" at Edge Magazine:
    Alex Wiltshire: "Have you worked with figures that aren't in the acting world?"
    Lev Chapelsky: "Celebrity acquisition applies not just to celebrity actors but to sports figures, politicians – we've made offers to Bill Clinton for videogames and gotten great responses with attorneys who have said, 'The former president will not participate in one of your videogame products, thank you very much'. We appreciated that frankness and candour – you don't get that kind of candour from Creative Artists Agency, frankly. If the answers no, they don't return your call for six months."
    Alex Wiltshire: "What project did you ask Bill Clinton for?"
    Lev Chapelsky: "I think that might have been to play the president in Fallout 3. Wouldn't that have been brilliant? You get to that point in game and you hear that voice in the ether coming from off-camera and you're like, 'I know that guy!'"
