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. While most plasma jockeys succeeded in their tasks, many simply disappeared after a few hundred years, and no one knew what became of them.
