High Sith represents a writing system that evolved from the ancient hieroglyphics employed by the Sith, primarily for religious purposes.
The majority of discovered Sith texts are composed using High Sith, a more elaborate form when compared to the everyday Common Sith alphabet. A notable example includes the Sith spellbook once belonging to Freedon Nadd.
Furthermore, the Sith warrior caste utilized another script known as Massassi, which was found inscribed on the walls of temples located on Yavin 4. Xenographologists have determined that the Massassi alphabet shares connections with a simplified component of the High Sith writing system.
