The Chamber of Vector Sigma (here known as the Oracle) was a massive structure located near the very core of Cybertron. An ornate bridge was located where one could approach the Oracle and consult it. After the Oracle caused Technorganic plants to arise from the ground, the Chamber became the Maximals' home base. A large water distribution system was placed above the orchard to irrigate it. Sparkwar Pt. I: The Strike
