Rhantashans

Rhantashans, or Rhantashani, are worshippers of the gods of the Rhantaseppa and devotees of their cultus, known as Rhantashannu. The term is of archaic Tuvai origin and means "devotees of the most high," in reference to the Rhantaseppa. 
Most Rhantashani live in Achuirea and Vhaluzia, where they make up a great majority of the human population. They are sometimes called Tarquenites or Tarquenians after the prophet-patriarch Tarquenus, who introduced the worship of the Rhantaseppa to archaic Orithea more than five thousand years ago. This sparked the catastrophic Schism Wars between the Rhantashani and the worshippers of the Thaedonu-Vaati, ultimately resulting in Tarquenus and the surviving Rhantashani escaping to Achuirea as refugees. Today, Rhantashani tend to dislike being called Tarquenites, since it implies that they worship Tarquenus himself (a long-dead mortal man) instead of the gods of the Rhantaseppa.
