The Sentinels a voice from down the ages, so in haunting in its song

Although Emaleth, too, was disoriented by this new sense— she was quick to accept it, quick to ignore the odd sensation to focus on the other wonders it provided.

Were it not for the whimper, Emaleth would not have known that something was wrong, and even so simply believed it to be in protest of this new change. She told her, then, "it will be alright, dear one."
