Like most of the inhabitants of the Draconian system, Chev knew very little of matters outside his specialty, which was combat. The plot was revealed by the Third Doctor, and instead of going to war against each other, the two empires united against the Daleks. The Master had allied himself with the Daleks, who were launching another bid for galactic conquest and hoped to pick up the pieces after a new Earth-Draconia War. These attacks turned out to be the work of Ogron mercenaries under the orders of the renegade Time Lord known as the Master, who was using a sonic hypnosis device to make the Earth crews see the Ogrons as Draconians and vice versa. In 2540, several incidents involving attacks on cargo freighters along their respective borders nearly led to the war turning hot once more, with both sides accusing the other of piracy and violating the frontier. An uneasy peace was negotiated in the end, leading to two decades of cold war and the carving out of a frontier between the two empires. The commander of the Earth ship saw what he perceived to be a battlecruiser bearing down on his crippled vessel and gave the order to attack, destroying the battlecruiser and triggering off a brief but bloody war in which millions of lives were lost. As a result, the Draconian ship was unable to respond to the Earth ship's signals. However, both Draconian and Earth ships were caught in a neutron storm, damaging the Earth ship and destroying the Draconian ship's communications systems.

The ship sent by the Draconians for the peace mission was a battlecruiser, as befitted a noble of Draconia, although (as agreed) its missile banks were empty and it was otherwise unarmed. The Earth Empire's first contact with the Draconian Empire was in the year 2520. For his services, the 15th Emperor made the Doctor a noble of Draconia. The Draconian Empire dated back to at least the 21st century, when a space plague that afflicted their world was dealt with by the Doctor.

The Draconian Empire was a vast spacefaring feudal civilisation of reptilian humanoids, centered on the planet Draconia, with a society stratifed along class and gender lines (for example, females were not permitted to speak in the presence of the Emperor) that was bound by a strong code of honour. In later interviews, Jon Pertwee cited the Draconians as his favourite of all the monsters he had encountered during his time as the Doctor. Unlike many 'monster' races in Doctor Who, the Draconians were articulate and portrayed as having a sophisticated and advanced culture like feudal Japan. Their only television appearance to date was in the 1973 serial Frontier in Space. They were featured in the British science fiction television series Doctor Who.

The Draconians are an extraterrestrial race.
