Dr. Maran Gannon ventured into the unknown of the Andes Mountains in August of 1922, only to return to England in September of that same year with an enigmatic madness about him. He fell into ruin, committing horrible acts in the name of his mysterious lunacy, and has never been found. Inside this publication are his journal contents, such as they were upon their recovery in October of that year. What the doctor saw during those months in the jungle filled his very soul with a fear so deep that it nearly killed him. Only in his own words can the horror of his discoveries be visualized.
