The main characters are the 13 Yule Lads. These characters have been part of Icelandic tradition for a long time. Each Yule Lad has a name and a particular behavior. For example, Bjúgnakrækir likes to lurk in rafters and steal smoked meat. The Yule Lads' actions and interactions with the local people during the Yule season form the basis of the stories. Their distinctiveness and the various situations they get into make them the central focus of the original Yule Lad stories.
