Zarola did not understand why her mother had written her mother had written about where they had come from. What she did not understand is that if she had continued to read, she would have seen why their clan was so special.
She did not know why her mother had given her the necklace with the pendant. She did not know that inside the pendant was a liquid that would activate the powers of the witches that used their blood to create them.
She also did not understand why the witch had known that she had the pendant.
The truth was that everywhere the pendant went, the witches would be able to trace it because it had their blood.
After many generations, the information about the pendant stopped being passed around, so the current witches had no idea because they were still descendants of the witches that were involved in the ritual.
