Zantrah
From Tardis Wiki, the free Doctor Who reference
Zantrah was the homeworld of the Zantraan race. They were forced to leave the planet when it was ravaged by a plague. The surviving population fled in a ship to find a new world. Finding the Earth undesirable, they repaired their ship and returned home, where the plague should have died out. (DWBIT: The Zantraan Invasion)
