Kind of, yes, but they live only in Brittany, no trace of them in other regions.They are known to live near dolmens and standing stones, where they drink all day (acorn beer, mostly) and at night, they get out to play music and dance, and then, if someone is reckless enough to cross their lands, they will compel him to dance all the night long, until he fall down or even die...Then, at sunrise, if korrigans thinks the guy was funny and a good dance pal, he will be granted a bag of gold, otherwise, he will be cursed with a bump on his back or a club foot...They are not bad guys, but you must avoid to cross their road either !
