The girls approached Margaret and bowed to her, they introduced themselves as Constans and Fidore, they were both twins and so the only thing that differentiated them was the shade of hair, Constans was the older sister and as she lifted her clothes Fidore did magic and covered them with lilac particles, They guided her to her room and prepared her bath where with rose petals and scented soaps they bathed her body, Constans lent her one of her clothes, although Margaret was a little long due to her height.
Constans: my lady, I can adjust it to your body if you wish, likewise when you learn the magic your body will change in many ways.
Margaret: Like my skin tome.
Fidore: no my lady, your skin will keep its beautiful natural color, here the magic is black, so you can extend your magic as you wish, the change will be drastic but you will see that it will make you stronger.
Margaret thought for a while and agreed to temporarily Constans accommodate the clothes, they walked her through the gardens, they clarified all the doubts of the book that had chosen her as its owner, the book although it was written in the language of other races, its owner could understand it perfectly and even the book would help her with the speech of dead languages, she could access the world of the dead and look for the body she wished to reuse as a defender or attacker to take care of her, the only requirement was to make prayers and sacrifices.
She was also told that if she did not comply with these rules, the book itself would reveal itself to her master and take her to the world of the dead to kill her; Margaret was not entirely surprised by this and understood that this could be called a "pact with the devil".
