Silicorundum

Silicorundum (演算中枢(シリコランダム)) is the mysterious technology that is apparently the center of the Tree Diagram's operations, its synapses. It is within the supercomputer, and in turn carried inside the Orihime-1 satellite.

It is rumored that Silicorundum is one of the Imaginary Technologies that originated from the Imaginary Number District–Five Elements Institution. However, since the place is not actually a research facility but a different dimension composed of AIM, the origin of Silicorundum is still unknown.
