I'm looking for an animated fantasy movie from the 1970s- 1980s. I thought that it was called fairy hill, but I'm not really sure, because I can't find any information on that title. I can't remember many specifics, but I remember that a human steps into a fairy circle or something and then ends up going on journey with fairies and elves to defeat the darkness. I'm not sure if that description made sense, but I've been trying to figure out the title to this movie for a few years and I can't. Any help would be great. Thanks!
