Dear Vector Prime, what are the names and characteristics of the planets within Cybertron's Beast-Era solar system? We see at least two other planets on Rhinox's monitor in "The Agenda (Part 1)."
Dear Orrery Observer,
As I believe I’ve previously mentioned, Cybertron has orbited many stars and had many sibling planets. The star that we orbit in the display you mention is named Hadean.
We on Cybertron call the innermost world "Zel", the Old Cybex word for the being you know as Solus Prime, as our ancestors arriving in this star system believed only she could forge such a glittering orb in the sky. The inhabitants of Zel often call their world "Samine", which means "paradise" in one of their languages. Planet Zel, being the closest planet to Hadean, is constantly buffeted by solar winds and ejected plasma from the star, and has an extremely unstable magnetic field. This gives the planet an illusion that it is covered in stormy auroras, which are dangerous to technological lifeforms like ourselves. We can only visit that world for very brief periods of time.
There is a bit of a story about the second world. After Paradron was destroyed, many of the Autobot colonists who lived there preferred to seek out their own world once again rather than remain on Cybertron, and so Rodimus Prime authorized a voyage to the new world. The Autobots discovered that this planet already had the presence of an almost-extinct robotic civilization. The Autobots and Paradronians managed to co-exist and the world was rechristened "Paradron-2".
In the native Paradronian language, they call their world "Gorlam Alpha", and strangely refer to Cybertron as "Gorlam Prime".
