Figment

Figments were creatures on Darbodia that gave the inhabitants imagination.

In a dream, Wargonn captured them all, since he believed they made the people disorderly. The Eighth Doctor forced Wargonn to release the Figments, restoring imagination to the Darbodians. (COMIC: The Land of Happy Endings)

Behind the scenes

 * It was later established that the adventure was part of the Eighth Doctor's dream, therefore it is unknown if these creatures actually exist.
