I have designed an early stage of my idea for a possible Oracle, Aphrosteria. The name implies that they may be female, but my original intention was to make the gender as ambiguous as possible, incorporating male and female attributes over it. They're meant to be emotionless, by that i mean, physically, they show no emotion, this however does not mean that they don't feel emotion. Like Michelle's idea , this will be ethereal, mysterious, with a lingering presense. This Oracle is capable of bestowing great sorrow and anguish over anyone who dwells upon it and is knows as something that had once suffered nightmares beyond belief and can recreat its nightmares within the mind into a reality around it. It's also pshychic.
This is still a work in progress, and probably totally what you don't have in mind Michelle. that's ok , we can still work with it :] Let me know any new ideas for the story so i can work with it more. I still need to grasp a better understanding of the story ;]
