Founders of The Region

The Founders of The Region is (presumerly) the leaders of Mesa Black. It is strongly implied that there is a presence of an oligarchy.

The King - They are an unknown individual who aims to indicate that a certain sample is analyzed. Several UNGC members also ask his age in the intro of Half life: Defense.

The Administrator - They are apparently concerned about the The King's aim.

The Vice President - The reach of their authority is unknown, aside from their power to decide what a microscope is.

The Directors - Prior to the experiment, they are assured that there will be "no problems."

Cup Manager - Apparently had their office located at the top of the stairs in Office Building. Given their proximity to the cafeteria, they are likely involved with the distribution of cups in Mesa Black.

Mason Black - The namesake of the training course in Mesa Black. He is presumably a prominent scientist, leader, and/or financial donor of the organization.
