Hello everyone, before I continue from my last post, I would like to give a little background of the Brotherhood of Steel. Brotherhood of Steel was a US military group of soldiers that was ordered to overseer the experiments on energy weapons. Story begins when the group discovered that those scientists, under the order of US government, which was renamed later as Enclave, were using involuntary human as specimens; the group then killed all of the scientists and declared themselves independent from the US army. The Great War started not long after that. The group survived the nuclear exchange and radiation by highly effective radiation protection protocols of the base. Not very long after the Great War, the group decided to desert the base, taking schematics and all experiment results with them. The group, then, with extremely advanced technological knowledge named themselves as the Brotherhood of Steel. 200 years after that, the BoS has gained enormous power and spread out into the ruins of US. The Washington DC division of BoS has taken the former Pentagon and renamed it as the Citadel as their headquarter in Washington DC; this is where the player and the scientists fled to.


     Before the story, the BoS was interested in Project Purity and has been offering help in many ways, however, tension rises for the BoS when their nemesis, the Super Mutants, begins to gain their power in Washington DC. The Super Mutants are humans that were infected by a virus called Force Evolutionary Virus (FEV) which was developed by US government themselves, and turned into monsters. The BoS, then, slowly back off from Project Purity to concentrate on these Super Mutants, and eventually left their support on Project Purity. The scientists of Project Purity, knowing the elder of the BoS, decided to flee to the Citadel with the player.

     After they have reached the Citadel and inform the elder about the death of player's father, the elder explained to the player that whatever the Enclave plans to do with Project Purity, it will require password and a technology called the Garden of Eden Creation Kit (GECK). The GECK is a technology that was provided within each Vaults. It contain technology that would, basically, create an Eden, a place habitable for human to live in without radiations and give life back to radiated soils for growing crops. This technology is required to run Project Purity, therefore the elder asks the player to retrieve this technology before the Enclave does. However, after the player has acquired the GECK, he or she is captured by the Enclave along with the GECK.

     The player is, then, taken to the Enclave's headquarter and meet with the President of the United States, John Henry Eden. The player learn that the present Eden is an artificial intelligence, or basically computers. Because he does not know the password to the Project Purity, Eden asks the player to make a choice. He gives the player a modified FEV virus and tells the player that if this virus is inserted into the Project Purity, the irradiated water, instead of purifying it, will turn into poisons that will kill many mutants along with many innocent people. Eden, then, free the player and leaves the choice to the player. The player returns to the BoS, with GECK, and begins the take back of Project Purity.
