Ulian-Quintani War

The Ulian-Quintani War was an interplanetary war between the Ulian Empire and the Quintani in the early 21st century. The war ended within two years.

During the conflict, the Ulian Empire created guard robots to protect Princess Cilia. When the princess' ship disappeared in the Sol system the robots tracked it down, but instead of finding the princess they encountered the Tenth Doctor, who had tracked the ship's distress signal. The robots initially attacked the Doctor, believing him to be an enemy, but he was eventually able to persuade them that they needed his help to find the princess. (PROSE: The Doctor on My Shoulder)
