Golems

Golems are the race of A.I. robots created by the now-extinct Progenitors. "Golem" is a name granted by humans. The Golems call themselves Karahola, or "machine people". The Golems were created by one of the two rival factions in the intraracial civil war that killed off the Progenitors in order to kill the other faction. After the Progenitors killed themselves into extinction, the Golems decided to maintain the remnants of the Progenitor civilization.
