SecondGen White-Blue was a second generation Sentry. In 2381, White-Blue went to investigate a Null incursion outside of its home system. This investigation led to the destruction of White-Blue's shipframe and its discovery by the USS Titan. This discovery led to White-Blue's nexus core, essentially its brain, being taken aboard the Titan where it made contact with the ship's crew. Shortly after White-Blue made contact, SecondGen Cyan-Gray entered the area in order to salvage White-Blue's shipframe and attacked Titan, taking it for a threat. In order to stop the attack White-Blue was forced to enter Titan's computer system and send a message to Cyan-Gray, while in the computer he sensed an intelligence there and offered it the chance to become sentient, an opportunity which it would accept.
