An immersive in-world guide to the Supernatural universe, this tome from the Men of Letters’ archive features information on the most deadly ghosts, monsters, and creatures ever encountered. The Men of Letters was a secret society dedicated to accumulating knowledge of the supernatural and arcane mysteries. Decades after the order was wiped out, Sam and Dean Winchester inherited their hidden bunker, where Sam compiled the records of the supernatural entities discovered by the Men of Letters into one book, along with additions and annotations from the Winchester brothers, themselves, informed by their time as hunters. From the Knight of Hell Abaddon to banshees and wendigos, this fully illustrated tome will allow fans to explore the creatures of Heaven, Hell, and Earth from the Winchester brothers’ perspective.
