The Persians

The Persians were an ancient Tribe descended from Zarathustra, founder of Zaroastrianism. They were easily as old as the Pharisee and they believed in God as the god of light and truth. They had a nature and abilities very similar to the Order of Acolytes, developing various powers around the control of light and darkness.
The decline of the Zaroastrian religion has left the Tribe a refugee population in modern times. Outside of India and the Mid-East they are effectively extinct.
