Ashtallah was a planet that was the home of the Ashtallan race.
Profile[]
Ashtallah had "rolling green hills, blue sky" like Earth but was much smaller than the human homeworld, despite having some similarities in its atmosphere and appearance. A large mountain range existed on the planet, bordering the valley of the Ashtallans. According to the First Doctor, it was on the other side of the galaxy from Earth. (AUDIO: The Invention of Death)
History[]
After the First Doctor, Susan, Barbara and Ian had left the Great White Hurricane in 1888, the Doctor attempted to use a temporal slingshot to return to 1963 London only for seventeen separate system failures to instead throw his TARDIS off-course and onto Ashtallah.
After the four had met the Ashtallans and discovered their immortality, the Ashtallans began dying off. It was soon discovered that Sharlan was the cause, using a sample of Barbara's blood, taken after she'd been injured, to kill her people in the hopes that a shorter lifespan might increase innovation. After Sharlan fell to her own plague and a vaccine had been developed for the rest of the Ashtallans, the TARDIS crew left the planet, pondering the impact that they'd had on Ashtallah.
