BRINE

came from the same cloning area as tuppoi and vienis.
is classified as a sister by tuppoi and N', but a brother by vienis (they quite literally have no gender. genes fucked)
after tuppoi and vienis dissented, they managed to run away and dissent after a chemical explosion left them disfigured and mutated.
though after that explosion they made it their duty to dedicate their livelihood to biological science. which lead them into hiding underground in the wasteland so nothing could come between them and progress.

they eventually get discovered by tuppoi and thrown onto N's radar consequently, so they have contact with both of them but they don't really.. respond frequently as Brine is usually laser focused on experiments. this easily gives them a cold and rude demeanor since they literally Dont know how to socialize.

due to their scientific prowess, they ship their chemicals off to whomever makes the biggest bet and uses the funds to order fabrication for new equipment. usually via tuppoi.
