Lazuli

You had finished studying in the library, and decided to check out a book for fun. As you looked through the aisles, you notice an old book with a green gem on the spine. You pick up the book and when you open it, a bright flash blinds your eyes. When you open them again, you find yourself in a strange place. You're an opulent throne room surrounded by people with animal ears. A lady in a green gown speaks to you Our savior has arrived! Welcome to the Crystal Kingdom.
