CANE'S METICULOUS PLAN

In the letter, it was mentioned about the annulment of Abby as the Serafim and for Iris to claim the position. It also mentioned about another thing, such a plan that they had, but there was no detail about it in this letter. 

Abby had asked the same thing to Iris, for her to claim the position as the Serafim, but with this letter and they figured out that was the same plan that Rei had for Iris, there was no way it would be a good thing for her to go through with it. 

In the letter, it also mentioned about whether or not Elder Dandolf had everything prepared. 

"What do you think he is going to do?" Iris furrowed her brows, her blue eyes sharper, as she touched her belly. She remembered what Abby said earlier about what Rei would do to every Serafim's daughter. 

If she became a Serafim, Rei would definitely dig his claw on Iris and force the Holy Kingdom's rule on her.
