Vex Sol Collective
The Vex Sol Collective is an unnamed Vex programming collective found in the Arcadian Valley on Nessus, Echo Mesa on Io, and the Fields of Glass, Mercury. These Vex have bronze frames with a seafoam patina, with some such as Storm Minotaurs and Axis Minds having a more pronounced patina.
The history of this new Collective is largely unknown, as its members weren't encountered until the Red War. It is unknown when the Collective arrived, or if they were always present. Evidence points that it is the largest Vex collective in the Solar System. It is most likely the central/largest collective, due to how many Axis Minds are in charge of it. They may be direct descendants of the Precursors, who converted Mercury, due to their heavy presence on that planet.
They are also responsible for the conversion of Nessus into a machine world, and are attempting to do the same for Io. Strangely, it is unknown if they have a presence on Mars or Venus, both of which are hubs of Vex activity and incomplete Machine Worlds, though it is possible the Vex as a whole may have been driven off of Mars due to the efforts of the Red Legion
