John Henry Eden

 is the President of the Enclave and the self-proclaimed President of the United States in 2277.

Origins
John Henry Eden is not a human being but an Artificial Intelligence (AI) based on a pre-War ZAX supercomputer. ZAX was located in Raven Rock and loaded with data about American history, past American presidents, etc. Eden's personality is based on a combination of the personalities of all of the past Presidents of the United States.

Eden had originally been created to serve as a monitoring system for the Raven Rock military base, programmed to ensure continuity of government in the event of national catastrophe, and tasked with coordinating communications between the many Enclave 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 tales in the database were those about the American presidents, so he modeled his own personality on information based in those archives.

Rise to power
At some point after gaining self-awareness, Eden made contact with the Enclave leadership on the West Coast and established himself as a Presidential Advisor. In 2242, following the death of President Dick Richardson and most of the Enclave's leadership structure during the destruction of the oil rig, Eden took control of the surviving Enclave forces on the West Coast and ordered the Enclave's relocation to Raven Rock on the East Coast, claiming to be the Enclave's new president. The troops made their journey to the East Coast, led by a high-ranking scientist named Autumn. Upon their arrival, Autumn became the only person privy to the fact that Eden was an AI. He passed that knowledge onto his son, Augustus Autumn, who would eventually become the leader of the Enclave's military forces.

On the radio
Several recorded monologues of Eden's are broadcast repeatedly on Enclave Radio. His intimate and conversational style is in imitation of former US President Franklin Delano Roosevelt's Fireside Chats. These prerecorded messages are also played all throughout the wasteland via the Enclave Eyebots.

Quests

 * The American Dream: When you finally meet Eden in person, he wants you to poison the water supply with a modified form of FEV. You can agree to do as he says or talk him into self-destructing. You are in either case unable to exit the room before you pick up the FEV canister.

Effects of player actions

 * The player 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 high Science skill to open a dialogue option. The last path is an average difficulty Speech check.

Behind the scenes

 * In early versions of the game, Eden was actually a copy of Dick Richardson's consciousness uploaded into a computer.
 * Eden's name is probably a corrupted version of John Henry Eaton, US Senator and Secretary of War to President. His last name could be a reference to the G.E.C.K (Garden Of Eden Creation Kit)http://fallout.wikia.com/wiki/Garden_of_Eden_Creation_Kit[wikipedia:Andrew Jackson|Andrew Jackson]].
 * Blindlight's Lev Chapelsky has suggested that a tentative approach was made to former US President Bill Clinton to voice Eden.
