Back -- and actually not too much to say on the last bit, I absolutely loved the line:
The light seemed to concentrate itself around her, casting the rest of the room into shadows.
Combined with the earlier mention of fairy faces it gives the reader a little doubt as to whether there really is magic at work -- which could be fun to play with as a story element, or just to let be as it is.

I like the plan, too. Very scheming and grandiose! I think it's important to give some more information about their history -- how they ended up as three outcast women here -- but I don't think that's needed (or even good) in the intro, just an element to include later.

Again, really really nice...half conspiracy, half fairy tale...I likes it!
