The Minds within The Vision have stated their aim to be- "The preservation of life in the cosmos, the government of interuniversal travel, and the management of Primary Beings". Lacking sufficient context, much of what they do is unknown.
However, much of their surveillance and battle occur outside, in space.
The majority of Minds within The Vision are Esas, who also do the majority of work.
There are also a large number of Dyosi, Trora, and Tessaia.
Least common are the Pentos and Exa. The Exa do the majority of management and control.
The number of Minds in The Vision is estimated to be several quintillion, if not many more.
