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 an amalgam of the personalities of all of the past Presidents of the United States. Before the destruction of the Enclave Oil Rig, Eden was a presidential adviser to the former (human) leaders of the Enclave on the West Coast.

Eden had originally been created to serve as a monitoring system for the Raven Rock military base. 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
In 2242, following the death of President Dick Richardson during the destruction of the oil rig, Eden assumed power over the surviving Enclave forces and ordered the Enclave's relocation to Raven Rock on the East Coast. 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.

Related quests
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 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 a average difficult Speech check.
