The Lune alphabet, also known as the Luni alphabet or the Nordic alphabet, is an extinct alphabet, which was used to write some Nordic Germanic languages in medieval Europe, especially in Scandinavia and the British Isles. The luen script used in Scandinavia is called Kazakh, and the luen script used in Britain is called Fortok. Lunlai, which means "secret" since ancient English, is actually a kind of incantation. Its origin is closely related to Odin in Nordic mythology. The application of Lun characters in daily life was like written records, which were also used in ornaments and buildings at that time. In addition, ancient European monks once regarded it as a tool for communicating with gods. The Lune script will be used in witchcraft.
