Elizabeth Grey

Doctor Elizabeth Grey is the head of Unnatural Sciences at Requiem.

Early Life
Elizabeth Grey was born in the United Kingdom. Not much is known about Grey's past other than that.

Recruited by Requiem
Grey had a lab in Bristol, which she worked in with colleagues Pip and Sam. When the outbreak zones began to form, Grey was drafted by the government to be the representative of Unnatural Sciences for Requiem, a newly formed organization designated to combat the efforts of the Soviet Union and the Omega Group.

Studying the Dark Aether
Grey then began her work at Requiem, studying the capabilities of the Dark Aether. She dubbed the parallel world as the "Dimension of Death" and began studying the mysterious material known as Aetherium.

Grey later noted after the Outpost 25 incident that the breaches into the Dark Aether had been random and have had to scramble to react to its random appearances. She then created a device that could help Requiem to solve that problem in the terms of research gathering.

Continuing her study of Aetherium, she began to wonder why it affected people differently and why the infected take on many forms, noting that some remain humanoid and some are more evolved creatures.

She also noted the possible benefits that could come from the Dark Aether. She explains her hypothesis by suggesting that there could be a way to keep the benefits that come from the Dark Aether and discard the bad stuff. She cites Herbert Boyer's revolutionary contribution to science, insulin, as an inspiration for her thoughts.
