Ergokinesis (also called Energy Manipulation) is the ability to project and absorb, and manipulate energy for various effects. Rephaim are the only species known to possess this power. The Rephaim can move, alter, or stop energy in themselves, objects, beings, or space. They can convert one type of energy into another, store it within their bodies, and release it upon command. Some can create objects from pure energy, or project it out in other forms. They may be able to absorb ambient energy convert it into Life-Force and live solely off of that, especially in supremely hostile situations.
