DXMD trophy Fresh out of the Package

Nathaniel Brown is a billionaire business mogul, and the CEO of the construction company, Santeau Group.[1]


Following the Aug Incident in 2027, Brown and his company vow to make "safe havens" for augmented people where they can be free to live and work without discrimination. Santeau calls this project the "Safe Harbour Initiative," with the flagship project being Rabi'ah, a city to be constructed in the Omani desert using large scale 3D-printing.[2] As he is also a firm believer in arcological design, Brown envisions the city to have zero carbon-footprint and be fully self-sufficient.[3] Due to his support for augmented people including hiring them to work on Rabi'ah, Brown has become a notable opponent of discrimination against the augmented.[1]

In 2029, the Illuminati are working towards the passage of the Human Restoration Act, which, if passed by the United Nations, would severely restrict the rights of augmented people. If the Act passes, Brown and the Santeau group would stand to lose trillions, as Santeau would not be able to sustain the influx of augmented people to Rabi’ah. Given Brown's expected opposition to the Act, Brown therefore poses a significant threat to the Illuminati's agenda, especially given his power and money.

After Talos Rucker is assassinated on the orders of the Illuminati, Brown holds a conference at London's Apex Centre, titled the Safe Harbour Convention. The goal of the convention is to host UN delegates and urge them to oppose the resolution. In response, the Illuminati plan to deploy their Shadow Operatives to attack the Apex Center, with the objective of assassinating Brown and the delegates using the Orchid poison.

Despite being informed by Task Force 29 that terrorists are planning to attack the conference, Brown pushes forward, with the belief that canceling the conference would only let the terrorists win. Irate at even the idea of canceling it, Brown threatens to invoke the Corporate Sovereignty Act if he doesn't get his way with security details, so TF29 gives in and helps with securing the event.

TF29, including Adam Jensen, arrive at London to thwart the attackers. If Jensen succeeds in preventing the assassination of Brown and the delegates, the Human Restoration Act fails to pass. However, if Jensen fails to prevent the assassination, the Act passes, thereby sealing the fate of the augmented.
