Made completely and freshly from Black Matter, Forceless Newborns haven't truly settled on a shape to take yet. Very weak compared to the more experienced warrior class Forceless, Newborns are little more than cannon fodder created from other creatures in the Collective capable of self-generating Black Matter.
No one knows the origins of the Forceless, but one particular group of them - only known as the Forceless Collective - has recently gained notoriety during the Valkoran War. They have been given the name from Force Sensitives due to being a dead-spot in the Force, something all life is otherwise connected to. So, theoretically, they shouldn't be able to exist, yet they do. Black Matter - the base form of Forceless - starts off as a formless puddle of sentient black goo. If they don't settle on a pure Black Matter form, they will often resort to possessing other lifeforms, often mutating them. If the host willingly pledges his/her allegiance to the Forceless Collective, they retain their free will. If the host refuses, the symbiote will take control of his/her body while they remain consciously aware of what's happening to them.
