Oracle Tank
From Transformers Wiki
The Oracle Tank is a location within the chambers of the Stellar Galleries in the city-state of Iacon. It is believed by the Council members to be a means to communicate with the Vector Sigma mainframe, and the consciousness they assert resides within it. As such, it is often used to test the mettle of potential Primes.
Fiction
Dreamwave Generation One continuity
Optronix communed with the Oracle Tank before ascending to the rank of Prime, though he doubted the Ancients' claims that it was sentient. The War Within #1
Sunstorm would later claim to be on a holy mission for the Oracle. This might have been genuine, as Shockwave's meddling with Vector Sigma had alerted Unicron to the location of Cybertron. However Sunstorm's programming was so addled by the dump of Vector Sigma's data banks that he proved to be less than stable. Black Sunshine
