The Librarians series focuses on an ancient organization hidden under the New York Metropolitan Public Library, which protects the world from the magical and secret reality that surrounds us. This interesting group of characters solves impossible mysteries, fights supernatural threats and recovers powerful artifacts from around the world. Among the objects kept in the Library are the Ark of the Covenant, the Holy Lance, the Holy Chalice and the Excalibur. Only someone with special skills can gather and protect these artifacts and, more importantly, make sure they do not fall into the wrong hands.
