And since she ended up on the fishing island of Rogonda, something is clearly going wrong there and her help is needed. But first we need to find out why the city residents are afraid of the Night Birds and the Lighthouse Keeper, what is hidden behind the Darkness that comes with the third strike of the bell, and who are the sea bodies that everyone talks about only in a whisper?
