Tivolian

Tivolians were the inhabitants of the planet Tivoli.

History
Tivolians were one of the oldest species in the galaxy. Their home world was conquered multiple times. (TV: The God Complex)

The Fisher King invaded Tivoli in the 20th Century. He ruled for ten years before he was overthrown by the Arcateenians. The Tivolian funeral director, Prentis took the Fisher King's body to Earth in 1980. Prentis then met the Twelfth Doctor and two other humans from 22nd Century. However, the Fisher King was still alive, so it put coordinates on the spacecraft. When Prentis came back to the spacecraft, he saw the coordinates, but was killed by the Fisher King. This turned him into a Transmitter Ghost for the coordinates. (TV: Before the Flood).

Culture
At first glance the Tivolians were a society of cowards. They never defended themselves and did everything they could to make their conquerors as comfortable as possible. The Eleventh Doctor considered this to be an aggressive form of cowardice. The Tivolians didn't fight; they survived by outliving their conquerors. (TV: The God Complex)
