Korrigans are supernatural beings of Breton folklore, often linked to fountains, caves, dolmens, and other ancient places. They may appear as beautiful women who dance at night, offer riddles, lure travelers, or punish those who violate sacred spaces. Their character is not simply good or evil; it reflects the danger and enchantment of landscapes shaped by memory. In poetry, a Korrigan can guard a well of ancestral speech, embody seductive geography, or make beauty feel like a test whose answer must be given before dawn.

A korrigan is a Breton supernatural woman or fairy, often linked with springs, wells, standing stones, caves, and moonlit landscapes. Stories may portray korrigans as alluring and wise, but also dangerous to travelers who break taboos, accept a deceptive invitation, or encounter them at the wrong hour. The term is especially useful for poems combining beauty with peril. Related concepts include Celtic fairy lore, enchanted waters, sacred stones, riddles, dancing, and transformation. Spellings and descriptions vary, so a poem can draw on the broader atmosphere of Breton legend without presenting one fixed appearance.
