Crusaders

The Crusaders comprised a subset of droids belonging to the Second Revelation, which itself was an organization of sentient droids tasked with locating additional droids of their kind. In the period spanning 3 ABY to 4 ABY, a Crusader identified as Petyr was assigned to an Imperial I-class Star Destroyer; his existence came to an end when he was destroyed by Imperial droids that had fallen under the influence of the Scourge.
