Gametitle-VBThe following is based on Van Buren and has not been confirmed by canon sources.

Derek Greenway was a scientist working under the employ of Poseidon Energy.


When it became apparent that Poseidon was more interested in the development of weapons of destruction, and less in the saving of mankind, Derek resigned and started his own company. Greenway Hydroponics, with its turnip headed stick man logo Mr. Green, was the result. In contrast with Poseidon, his company used Roman codenames, as opposed to his former employer's Greek.

Over the years Derek's company prospered due to their state of the art innovations in farming technology. When the Nursery project was put up for bid it was only natural that Greenway Hydroponics won and construction was began.

Vault 29's experiment was devised by scientific genius Derek Greenway. He wanted the Vault to be populated by older parents with infant children. The parents would most likely pass on soon after insertion into the Vault. Instead of a human controller, Vault 29 would have a ZAX super-computer. ZAX would be programmed to raise children with the aid of robotic helpers, educate them in the primitive culture, and upon their reaching maturity, release them into a controlled environment. They would then be free to rebuild society from the ground up.

At one point Greenway explained his plans for Vault 29 to Diana, the human brain connected to a powerful computer, to see what her opinion would be. He was quite surprised when Diana was appalled at the idea. She said that, although the idea had merit, she found it to be morally objectionable on several levels. She recommended that the plan be scrapped. When Derek refused to do so, Diana took it upon herself to become involved with the project without his knowledge.


Derek Greenway was going to be mentioned in Black Isle's canceled Fallout 3 project, codenamed Van Buren.
