Together the group enters the cave, knowing that Echo must be inside. They wander for a little while, until they hear Echo’s voice leading them onward. They suspect a trap, but Echo doesn’t harm them, and they find her sitting alone in a lonely cavern.
Echo wants to know what happened to Zafir, but Nightingale refuses to say. She demands the Pontifex piece, which Echo refuses. She doesn’t want to hurt Echo for it, because of the promise she made Zafir. But she can’t leave without it.
After a brief argument, the Soul Stitcher arrives, and forced Echo to attack.
