Pleadians

A subset species of Humanity, the Pleadians are genetically identical, save for very rare and very obtuse mutations that occur within a small percentile of the population. These mutations produce odd results similar to what was seen in ancient Earth mythology, humans with animal heads, wings, etc.

Simulation State
As one of the older empires of the galaxy, the Pleadians eventually faded from public awareness as their civilization sank into their own minds through use of advanced mechanical simulation. Whole worlds within their home nebula have been converted into massive computers that communicate amongst each other as if singular beings, powered by the smaller creatures that are connected to the local matrix. These worlds are classified as technical hazards, graveyards in their own right, the minds that exist there are preserved and protected as last resort back-ups for in case the Pleadians that wander the stars should perish.

Neuromancers at Work
Individual Pleadians are found few and far between throughout the galaxy, each wielding such immense power that reality begins to breakdown and bend to their will as their minds are stretched across spacetime. With natural dispositions for extreme neuralkinetic abilities, the connection to different layers of simulation and dream boost this natural power, creating the continual need for 'Binding", a process by which a fully awakened mind is locked into another state of simulated dream, fracturing their consciousness into several other beings that serve their origin source and fight to be the next super-mind to undertake the ritual.
