Lyle Walt is struggling. His ancestors have given him a challenge to conquer thirty floors of Aramthurst's dungeon without using their Arts, but with his party divided, it's proving impossible. Aria and Sophia bicker with one another constantly, and Miranda only fuels the flames. Meanwhile Novem watches on without intervening, fending off Lyle's new automaton, who treats her with open hatred. And all the while, Lyle sits with his head in his hands, unable to see a way to fix the problems laid out before him. That is, until he finally discovers a possible solution—a new comrade.
