Some time after their involvement in the Human-Draconian war (TV: Frontier in Space), the Third Doctor and Jo Grant visited Draconia again, but at an earlier point in Draconian history. (AUDIO: Conspiracy in Space)

The Tenth Doctor included Draconia among his list of worlds with a mythology involving a "horned beast" of the likes that Earth and Dæmos had. (TV: The Satan Pit)
