The Knights of Velyshaa attempted to capture the Temperon in order to conduct time travel experiments; however, the creature, preferring death to enslavement, tried to destroy them, creating a temporal distortion which froze the creature and the Knights in a single moment of time. The distortion eventually became known as the Kurgon Wonder. Ellie later manipulated the Sixth Doctor into freeing the Temperon and the Knights that were trapped along with it. This allowed the Knights to capture the creature and use it to power their time machines, albeit at the cost of their slow, painful deaths.
