Scandinavian tales and creatures

Sjörån (watchers of lakes) guard lakes and ponds and all that lives within them. Unlike their sisters, skogsrån and skeppsrån, sjörån are much more protective and vicious. They will not tolerate anyone who tries to catch their fish or otherwise disturb the waters, and they will not hesitate to drag fishermen down into the murky depths of their lake to drown them.
