Eventually once the Second Galactic Empire had collapsed, the planet became isolated. (DWA: Plague World)

Plague and arrival of the Doctor
An insectoid race known as the Druden had secretly set up a lair in a valley located near the village which was named the Forbidden Valley. It was they who Bemar obeyed and their objective was to infect the humans with a plague so those who died from it, their bodies would be fed to the Druden young or otherwise they would die. The first part of their plan to was to infect the remaining population with the spreading infection. One human named Auctor who thought he had escaped was infected with the disease and as he went back to the village for help, he spread the infection around which then slowly the villager's were suffering from it except for Bemar who the Druden gave an antidote to her.

When the Doctor, Adric and K9 arrived on the planet in the village, the place seemed deserted. However all the people were having an assembly in one of the buildings arguing with Bemar about the trouble that was happening including the mysterious deaths and disappearances. During the argument, Adric spoke out which then Bemar accused him, the Doctor and K9 to be the cause of what was happening.

The Doctor who quickly deactivated K9 was able to escape with the help from Kidson, one of the villagers. Kidson showed the lair which the Druden were hiding and later before the Druden were about teleport to the village as part of the final plan, the Doctor activated K9 using a device to send a signal to which K9 used his photon beams on Bemar destroying the transmitter to teleport them and supposably killing her whilst Kidson flew his Strato-Cruiser into the cave sacrificing himself and killing all the Druden in a massive explosion burying them under a large amount of rock. The planet was once again allowed to prosper and everyone who was infected was given the antidote by K9 who manufactured more with the Doctor, Adric and K9 departing in the TARDIS. (DWA: Plague World)
