Narvin 1 (Shockwave)

One of the alternate versions of Narvin, created by a temporal shockwave caused by the War Master, was a farmer on an alternate Gallifrey.

Biography
When the War Master interfered with the Daleks' creation, a temporal shockwave was created. This resulted in many alternate timeline versions of Gallifrey being created. One version of Gallifrey had a medieval level of technology.

When the Unbound Master was visiting the alternate versions of Gallfrey, he encountered Narvin and his version of Gallifrey. (AUDIO: Shockwave)
