Ballustran

Ballustrans were a race from the planet Ballustra. They had a population of 8 billion.

History
A CVE appeared near Ballustra and emitted pressure waves, estimations suggested that 15% of the population were killed on the first day. A joint scientific and military group was formed to investigate the CVE. While flying near the CVE, they sighted the Doctor's TARDIS; through the use of a ship with "claws" they captured it.

They then deposited it on Letrus and took Romana and Adric prisoner. The pair were questioned by Marni Tellis.

They were then attacked by the Farrian who came through the CVE. They attacked Ballustra killing many more Ballustrans. The nations of Ballusta banded together, forming a single effective force. After the Fourth Doctor destroyed the CVE generator in N-Space the Farrian were forced to recall their officers and retreat. They left behind the ground troops who helped in the reconsruction of the planet. A planetary defence force was developed to fight any furthur invasions. (CC: The Invasion of E-Space)
