Castrovalvans were simple, peaceful people who lived quiet lives in their small village. They hunted for exercise and had a library with a complete history of Castrovalva. But The Doctor realised that Castrovalva and everyone in it was a lie. It was a trap created by The Master and nothing about it was real. When the Castrovalvan reality collapsed they all ceased to exist.
