Metralubit

Metralubit is a planet that was settled by humans in the fifty-eighth segment of time and is located in the Fostrix galaxy.

There were at least 6 civilizations on Metralubit. During the first civilization, The Darkness found it and started the feeding cycle. Each civilization was able to last around 2,000 years before The Darkness made it plunge into chaos. The Darkness was able to feed on the carrion and death that was created and then went back into hibernation.

The 6th Civilization
The sixth civilization was developing at the same rate as the first five civilizations. Progress moved slowly and the planet was polluted and dirty. Eventually, Menlove Stokes' cryogenics chamber was found. By extrapolating the knowledge in his mind, they were able to make great leaps technologically. As well, they were able to create the Femdroids from Stokes' memory of K-9. These Femdroids, being more efficient and intelligent then humans, were able to see the pattern of destruction.

The Femdroids decided the best choice of action would be to send most of the humans to Regus V. The Darkness would be then distracted by a war on Barclow. Eventually, The Darkness would move in to feed, when Barclow would be blown up, destroying The Darkness.

Unfortunately, this plan was stopped after meddling by Romana, K-9 and Menlove Stokes. (DW: The Well-Mannered War.)
