"Brown Berry." In the folklore of the Isle of Man, Berrey Dhone is a gigantic hag of a particularly aggressive nature. She will stride across oceans and mountains to defeat her enemies. She lived either on top of North Barrule Mountain or inside it and her rocky heel print can still be seen on the mountainside.
