Deva

A Deva is a human which has been so affected by the Light, beyond the point of no return, and now bears some physical and mental attributes that mark them as being different from a standard human. They are sometimes a mid-point between humans and angels. They often have glowing golden eyes, and a glow from beneath the skin, which shines through in fine cracks across their body, which become more prominent when they use their magic. Some may have white feathers in places, or even full wings. 
Unlike angels, deva are not mindless servants of the Light, and still posses the sapience of a human. They are, however, often quite strange to interact with, and often consider themselves above humans. They often walk a fine line between humanity, and divinity, which can make them seem out of touch, and apathetic towards human lives.
As the light power within a deva grows, their angelic side will often gain more control, slowly removing remnants of humanity within them, and turning them into a full angel. A strong-willed deva may be able to fight back, retaining them humanity and suppressing the divinity, though the physical changes are permanent.
Devas are less common than their dark counterpart, cambions.
