William P. Cullen

President William P. Cullen is the original founder of the Orion Nero Initiative organisation which was developed in 2054 during the first scenes of the Alvitr Central Security in the Alvitr Kingdom.

Biography
Cullen, although is the president of the entire organisation, is relatively insignificant and is only mentioned a handful of times such as during the initiation day for the protagonists who escaped Ansaris, Marcel Garrick, Alan Zeek, Timothy Kato, Rachel Mykelti, James Clayton Lacroix and Jason Morello; the Summit Meeting after Adrian Lux's escape from Sword Base with the help of Havoc Group; and his death during the battle of Santora.

Battle of Santora & Death
During the Battle of Santora, the ONI Headquarters is evacuated with all ONI representatives and staff escaping towards Trafalgar Stadium via a Puma convoy. However, Cullen did not participate in the escape and remained at his office.

Anvil Team and Onyx Team were tasked with rescuing Cullen from the building but failed to do so, with the president reluctant to leave. Cullen is eventually killed after an ACS Leviathan-class Light Cruiser crashes into the building, destroying both structures, with Cullen along with it.
