Aržang Of the Brothers of Light (Arion-Senpai)

When I was (barely,) birthed, somewhere in Manhattan, Mother Parastoo and Papa Raji debated on what would be a most befitting name, for me.

Raji demanded that I be called "Sean", for the sake of assimilating easier with the White people of New York, for a Persian name could remind me of the many traumas and struggles he and her had endured, in their past.

Parastoo disagreed: she had fared against a variety of Doctors, Nurses, and Naysayers, for extended periods of time, whom all suggested that I be aborted, due to her history of Drug Abuse, and Alcoholism. A Persian name would remind me of my heritage, and the strength my hereditary family had, when it came to granting me life, instead of Denying it.

She won the altercation, and chose to give me the name:
Aržang-"Worthy" in Persian.

The name of a Holy book, written by the founder of the notoriously stringent Manichean Religion; Mar-Mani.
Yet also the name of a Devil in the Shahname...
Which iteration is accurate?
