I like the idea behind the Sibyl, Djinn, and I think the abilities fit well. I am, however, worried about the power level. Those abilities look pretty strong and the class retains full casting. I think it might be too powerful. Make sure it's balanced and it will be a great class!

I'm going to try to enter as well, I'm trying to decide between ideas. I'll either do:

a barbarian turned monk who has learned to tap into the power of thier emotions like they used to, except instead of letting them run wild, the will be more controlled.

or the Forsaken of Pelor, clerics or paladins who revered the sun god but became vampires. Now they seek to restore their lost connection to the sun.

Right now I'm leaning towards the forsaken. I'd love to hear everyone's opinions.
