Dewyn

Dewyn was a peaceful planet visited by the Tenth Doctor and Martha Jones. It was the home of the Ancient Worlds Theme Park, which contained a huge collection of Earth artefacts. (COMIC: Minor Trouble) A Chiffala mercenary had crashed on Dewyn earlier, and was creating chaos in the park. The Doctor stopped him, chained him up in the park, and said he would return to check on him in a few months. (COMIC: Crimes and Punishment)
