Fulgardt's memories from the WILLS were greatly fragmented. Skullius had gleaned a great deal from them but not nearly as much as he would have liked. There was a lot about the Labyrinth of the Yoke and its purpose that was missing; there were other fractured bits of Fulgardt's adventures outside Aigas; there were lacking details about Fulgardt's encounter with the Wanderer Who Seeds.
Skullius had hoped to learn more about these subjects with the stunt he had pulled on Fulgardt. He was only half-successful.
Seeing Fulgardt turn docile was cathartic though. For once, the Immoral wasn't dictating how everything would end.
"What will you do with that information now?" Fulgardt asked.
"I'm yet to decide," Skullius said, "but rest assured, I won't be using it to dictate your actions. Much."
