Myodusa

Lore

Myodusa (묘두사) literally means “cat-headed serpent.” Legends describe it as a massive snake covered in gleaming, gold-tinted scales, crowned with a head that looks strikingly like a cat’s—or a wildcat’s. Ancient texts say the creature is so large that the depths of its cave remain unexplored. They also claim it emits a blue energy—seen as light and smoke—that foretells natural disasters. But let’s start at the beginning.

Unlike most monsters, Myodusa isn’t a predator and poses no threat to people unless provoked. It’s calm, gentle, and clearly intelligent: more a thinking being than a simple animal. Stories say it can sense weather changes, and its bond with nature is so strong that birds—especially crows—congregate around its cave, suggesting it may even guard them.

Myodusa lives in a deep cavern behind the main hall of Hwajangsa Temple in Songdo. The secluded spot, nestled in harmony with the shrine, underlines its mystical status. Other tales add that Myodusa understands every animal tongue, so local beasts and birds settle near the cave and attack any intruder, warning the serpent of danger.

Locals once revered Myodusa as a benevolent deity. Its signature power is a healing aura: the blue glow can cure any illness or wound. One story tells of a monk riddled with malaria who recovered simply by sitting at the cave entrance. For fifty years villagers brought offerings of incense, food, and wine.
