Who exactly is Nefarith?

So looks like the villain we faced in the first chapter (Nefarith) is actually someone who was part of the Endfield group and defected. Or at least involved with them during the GLOOM project, this smells like someone who could possibly become playable in the future with the right twisting of the story
Endmin amnesia is a convenient plot device and honestly I'm not 100% sure that all the characters around us are being fully honest about our past. Especially Perlica that seems to be overly keen in making us continue the colonization of this world.
Overall so far, the setting of this series seems to be quite leaning on the dark side, but I wonder how far will they go there.
