The legendary Mohan, a supernatural being tied to the mysteries of the natural forces, is believed to be present at the bottom of the Magdalena River in Columbia. The Mohan smokes and drinks, waits for women and drags them into his underwater home. He scares fish away and holds the nets of fishermen; sometimes causing them to drown. Whether the Mohan is the perpetrator or not, the Magdalena rolls corpses in its depths.
