Sonic Canyons

The Sonic Canyons are a location on Cybertron in the Generation One continuity family.

The Sonic Canyons are Primus' sensory organs, resonating structures allowing him to collect data from across the galaxy. This data is then processed into a more meaningful format by the Vector Sigma supercomputer. They are also the place where Siren was raised.
