It was ruled by Metalhawk.
Archon was one of the multitude of worlds colonized after the expulsion of the Quintessons from Cybertron at the end of the Age of Wrath through the use of space bridges. It was first world to be given a new Well of All Sparks to generate new life as it was already energy rich. It was given this new well via a ceremony started by Bluestreak.
Archon was later isolated from Cybertron after the Rust Plague spread there and the destruction of the space bridges, and was the site where Prowl and Bluestreak parted ways.
