Tivoli

Tivoli was the most conquered planet in the galaxy. It was inhabited by a species of rodent-like humanoids. They were one of the oldest civilisations in the galaxy, since they simply let invaders do as they wished. Their anthem was "Glory To " and their cities were designed to be comfortable for the invading armies. The Weeping Angels were the only species ever to invade Tivoli with the intent of killing its citizens, rather than subjugating them. Gibbis was a native of Tivoli. (DW: The God Complex)
