Ulla

The Ulla People were first a very intelligent and technological species. Their technology had developed too much and had overwhelmed them and so they had created a machine to rectify the economical damage they had caused to their home planet of Xirrinda. The machine was the Rain Of Terror. It caused their demise and so they were reduced to tribespeople who created thatched houses and keeping great paintings to remind them of what they were before and to warn them of the monster they had created.

Their ancestors had also created a machine that would deactivate the Rain Of Terror. It was hidden deep within the mountain, in a cavern beyond many endless tunnels. The Doctor helped to reactivate it and the creatures were instantly destroyed. (NSA: Rain Of Terror)
