The Graces

Creature - The Graces

(The following is an idea I had to explain what Angels, Demons and Spirits may really be .)

Graces: A being or Essence that have walked the earth throughout time
And into legend (Angels, Demons, Spirits etc..) Yet have not done so in a thousand years. They are brought out of a slumber when enough people who have deep religious faith prey in close proximity of their essence. These graces currently are in a static form such as a holy relic or holy spot, they are never the same from one to the next. In their dormant phase they emanate a slight feeling of religious bliss in those that believe, other just feel at peace (calm)

Faith: Those who have a deep faith emanate an energy that the Grace feed off.

Graces are not really affiliated with any god, maybe there are no gods just graces (thought to be the avatars of the gods)
Or the graces are tied to gods and all the gods of myth are real.
