How do you make a secret passage?

To create a secret passage, first choose a discreet location, such as behind a bookshelf or within a wall. Use a sturdy door or a hidden mechanism, like a sliding panel or a book that acts as a lever, to conceal the entrance. Ensure the passage is well-constructed and safe, and consider adding features like dim lighting or soundproofing for added secrecy. Finally, test the mechanism to ensure it operates smoothly and remains hidden from view.
