John Henry Eden

John Henry Eden was the President of the Enclave after the death of President Dick Richardson during the destruction of the Oil Rig. He assumed power over surviving Enclave forces and ordered them to relocate to Raven Rock on the East Coast.

He was an AI based on the ZAX supercomputer, located in Raven Rock and loaded with data about American history, past presidents, etc. His personality was based on an amalgam of the personalities of all the past US presidents. Initially, the only person who knew that Eden was an AI was Colonel Autumn (only Autumn could meet Eden in person for security reasons). Before the destruction of the oil rig, Eden was a presidential adviser to the former leaders of the Enclave.

John Henry Eden was the chief antagonist of Fallout 3. He wished to use Project Purity to achieve the Enclave's stated mission of purifying the Capital Wasteland. In fact, President Eden was a highly intelligent AI, which was gradually revealed through the course of the game.

The player eventually meets Eden in person, and is given the option to put a modified FEV into the purifier at Jefferson Memorial. Through a successful Speech option, as well as some choice dialogue, the player can convince Eden to initiate a self-destruct sequence which will destroy the Raven Rock Enclave base, including Eden himself.

John Henry Eden started as a monitoring system for the Raven Rock base. He slowly became self aware and began to study the extensive archives left to him, mainly those of the U.S. government. His favorite were about the presidents, so he modeled himself from the information based in those archives.
