PANTHEON, the Projected-Access Nodal Transuniversal Heuristic Electronic Operations Network, is a massive, multi-tiered system of networked artificial intelligences and subsystems (each collectively known as a node). It is the backbone of all Yamataian military communications and intelligence.
For secure civilian communications in Yamatai, see SYNC.
Sapient PANTHEON AI were previously assigned a rank but as of YE 34, they begin at the Santô Hei and get promotions just like any other person in the Star Army.
