Aru tells Keisha that the empire has expanded its control of the northern slab region. Two or more of the ambs are stationed at each of the seven strongholds. Keisha wonders if they will be able to defeat one of them, but Aru assures her that it will not be difficult. He tells her that he is the true core of the church, and that he has come to liberate the northern slabs. He says that he will liberate them so that they are not afflicted with "a frame spoke disease" . He adds that he learned that there were dangerous "humanoid automatons underground" , but that these do not seem to be "those either . . They need to learn to get to the bottom strength of the enemy . he says that they arent immortal, after all. They are armored up, and they will not hit them if they fire from a great distance. They will take out two of them in front of them first, he says, and then he will handle the "levitation" user .
