Ok, I guess I misunderstood you, no big deal. I'll drop the kobold-concept, that was just a random idea that popped into my head, and will go with something much more generic and diffuse. Since I know nothing of the people who gave the spirit life, their collective unconcious is a mystery to me.

Name: Asveh
Personality traits: A warm, compassionate, demeanor disguising a cold, hard pragmatism and manipulation. Asveh cares about his people, but only as a means to an end.
Appearance: It appears to every man, woman and child as a slightly more perfect version of themselves. In any crowd it has as many appearances as it has viewers, though it usually visits people when they are alone and/or in their sleep.
Its first appearance was in a dream, a number of very similar dreams simultaneously. A comforting presence, a quiet voice, whispering secrets and reassurences, indistinguishable from the dreamer's own self. Over many nights a bond was forged between the spirit and the people, until the day he showed himself to the people; their own greater selves descended to lead them all forwards.
