Erik Refilsson
Erik Refilsson was a legendary king of Sweden of the House of Munsö, who would have lived in the late 9th century. One of the few surviving Scandinavian sources that deal with Swedish kings from this time is Hervarar saga. The saga is from the 12th or 13th century and is thus not considered a reliable historical source for the 9th century. It says:
Skáldatal mentions that he had a court skald named Álfr jarl inn litli.
