In the Third Zone, Androgums were used for menial labour and the currency used was the narg. Although humans had not reached this part of the galaxy, they were known in the Third Zone as "Tellurians". The Third Zoners were familiar with transmat technology, and were adept at technologically augmenting other species, turning them into mega geniuses. Dastari sought to elevate the Androgums, as the civilisations of the Nine Planets were becoming older and effete. They also conducted experiments in time travel using the Kartz-Reimer module which measured 0.4 on the Bocca Scale, the Second Doctor explaining that anything higher could threaten the whole fabric of time. The Sixth Doctor even hypothesised that the Sontarans thought the Third Zoners were getting too powerful and would ally themselves with the Rutans.
Circa 1985, the several governments of the Third Zone pulled together to create Space Station Camera, where some of the greatest intellectuals in the universe gathered, including Kartz and Reimer. The station came under attack by the Sontarans who attempted to frame the Time Lords. (TV: 'The Two Doctors, PROSE : The Two Doctors')
