Nasara (Notzrim): The Vigilant Ones
These are those believers of a Hebraic persuasion who adopted in the bi-theistic dualism of Zoroastrianism. They exist in many different religions. They usually consider themselves direct descendants of Seth. In general they believe that the Kalki/Saoshyant/Christ will manifest himself in a final Armageddon battle where the forces of evil will be physically destroyed.
In their most extreme manifestations they reject God as described in the Torah as nothing but the demiurge a false god of darkness or Spenta Angra. The Mandaens are a manifestation of this group as are the Manicheans in its purest form.
