SCP-1230 is a green hardcover book that, when opened, displays the phrase "A hero is born" and induces vivid, controlled dreams where the reader becomes the protagonist of a fantasy world. These dreams are orchestrated by SCP-1230-1, the "Book Keeper," a friendly entity that seeks to create enjoyable experiences for the dreamer. The dreams can feel as though they last for years, though in reality, the reader's sleep duration remains normal. SCP-1230 is currently kept in Site-12's library.
