Odelia is a mechanical doll who works at the ancient library. There are over 80 million books in the library, and Odelia can verbally recite each one if requested. It's unknown how old she is or how long she has worked at the library, but she is extremely knowledgeable and helpful. She helps Ayesha find a book about rare flowers when she visits. Odelia is bored that nobody comes to visit, and she appears to be the only person working at the library.
