What is norse siren?

As an AI language model, I do not have access to any specific information about a "Norse Siren." However, "siren" is a term typically associated with Greek mythology, specifically referring to creatures who lured sailors to their doom with their irresistible songs. Norse mythology has similar creatures known as "draugr," which were undead beings who lived in graves and were said to lure travelers to their deaths. However, it is unclear if there is a specific mythological creature referred to as a "Norse Siren."
