and they rose without another word and followed cassandra , for they would go to the place of genesis , to the ground which first held the tender body of willow , to the site of first alliance with the prince of darkness , and there they would appeal to ahriman and he would take the unborn child from a willing womb and together they would carry the infant to willow , to lay the child among the roots of the tree and invoke the power of the lord of the night to raise the sister of cassandra from the cold ground , complete and whole , and they would all rejoice in the union .
