Plasma jockey

Plasma jockey was a colloquial term used by Forerunner Builders to refer to stellar-class Forerunner Engineers equipped with third-class ancillas. Plasma jockeys were tasked with "taming" young stars for future use. It is also possible that these are Huragok, which would explain for being the lowest class, as they are artificial.
