049 Abject Testament (Earth-2042)

"We deserve to be forgotten."

- 049 Abject Testament

03-049 Abject Testament was a Forerunner-created ancilla designated as the Metarch-series monitor droid of Installation 03. The nomenclature describing him denotes his position as it relates to the third ring and his name was meant to represent both an omen and an epitaph for Forerunner civilization. Tens of thousands of years prior to Installation 03's discovery by the Galacic Republic, Testament stopped directing the functions of the ring.
