I'm thinking of writing a fan fic about the early history of Mondas, and I'd like to try and get some details cleared up. We know from The Tenth Planet that Mondas, the original homeworld of the Cybermen, was once Earth's twin planet at some point in the distant past, and that some kind of cosmic cataclysm resulted in it breaking its orbit and drifting off to the far reaches of the solar system. However, there's no concrete date for this event. When the TARDIS crew travel back 65 million years in Earthshock, Mondas isn't visible when they're orbiting prehistoric Earth, so I reckon its date of creation was sometime after this, possibly an accident caused by alien technology.
David Banks, in his Cybermen book, postulated that Mondas left Earth's orbit around 10,000 BC. But there's something else to consider: The Daemons were active on Earth in prehistoric times, and were actually responsible for destroying the Neanderthals, who are thought to have died out around 25,000 BC. I personally think that the departure of Mondas would have to have occured prior to the arrival of the Daemons, maybe around 30,000 BC.....but the Mondasian Cybermen that return to Earth nearly 32,000 years later don't seem nearly as advanced enough. Surely if they'd been developing on Mondas for all that time, they'd have progressed to something more spectacular and advanced than what they were when they finally returned in 1986?
P.S: Regarding the origin of the early Mondasians, I have a theory that they were descended from some humans from Earth in the last 150 years or so, who were caught in a time/space storm and deposited on Mondas thousands of years in the past, when humans on Earth were still in a very primitive state.
