The Helm of Awe
The Helm of Awe or Helm of Terror (Icelandic: Ægishjálmur, Old Norse Œgishjalmr) is an object in Norse mythology and subsequently the name of an Icelandic magical stave. The symbol used for the reference in the sagas came from the Huld manuscript written and collected in 1847. It was used as a part of a Christian magic ritual that has had some movements rooted in Icelandic culture but was a very common ritualistic practice across Christendom.
