The biologist’s thoughts that Area X is the “only place that exists,” and that the outside world is completely unreal, further suggest her unreliability as a narrator. She has become so affected by and immersed in Area X that she has lost her grip on the world beyond what she can see in front of her. And here, the book begins to illustrate how the lighthouse, though a traditional symbol of refuge, now seems just as insecure as the rest of Area X. It is now the home of something unknown, and its light, which is usually its guiding beacon of safety, is both literally and symbolically snuffed out.
