𒇌
The word ben (rendered in the First Runes as "𒇌") is a rare component of Mannic surnames. Ben is Mannic word for "of" or "originating from," and its application in a name demonstrates sole origin and is usually reserved for those who were not born but created by a single person or entity.
For example, Deshen's full name was Deshen ben Beld, as he was created by Beld. Subsequently most of Deshen's children, who similarly were created solely by Deshen, took the surnames "ben Deshen" in recognition of their creator.
