" Then Lyra gave a cry so passionate that even in that muffled, mist-hung world it raised an echo, but of course it wasn’t an echo, it was the other part of her crying in turn from the land of the living as Lyra moved away into the land of the dead. “My heart, Will …” she groaned, and clung to him, her wet face contorted with pain. And thus the prophecy that the Master of Jordan College had made to the Librarian, that Lyra would make a great betrayal and it would hurt her terribly, was fulfilled. "
