Why The New Queen Of Witches Is Hidden?

Zelda let out a sigh. "The new Queen of Witches was indeed born twenty years ago, it's just that our sights had been blinded, making our race unable to gain certainty of her birth. If she had died, those with the gift of foresight would have felt it, or at least be given a proper vision. However, that was not the case. That was why her life or death had become a dilemma none of the witches could solve, but I for one swear on my soul that she exists, but that is all I can confirm. Your Majesty, the entire witch race doesn't know her existence, much less where our new Queen is. 

"Think about it, is it even possible to hide her from us witches? If someone hid her then who can it be? Someone who is powerful and cares for the witches. Someone who doesn't want the Queen's existence to cause any disaster."

Everything pointed towards Evanthe. 

"Did you come across Evanthe?" Draven asked.
