Mythology
Nightscare's race are the Shadofigura, sister species to the other dominant species on Phanta Wraith, the Sawisps. Originally, all of the spiritual energy from across the universe somehow ended up on planet Phanta Wraith. Over the decades, that spiritual energy would bond with Dark Matter, the natural energy of space.

While the Sawisps gained more spiritual energy and less Dark Matter, the Shadofigura gained the opposite, getting less spiritual energy and more Dark Matter. Both species would both be hunted into near-extinction due to their unique body make up. To combat this, both the Shadofigura and the Sawisps gained unique abilities no other species before in their universe has.

The Shadofigura gained the ability to possess and manipulate people through shadows, as well as shoot concentrated Dark Matter.
