Professor Gryffen was a scientist in the year 2050, employed by the Government agency known as The Department. He created a Space-Time Manipulator, which generated a time-space rift into which he got trapped. K-9, who had escaped Gallifrey's destruction in the Last Great Time War, pursued two Jinxen warriors through the rift, rescued Gryffen and brought him back through the rift. He lived in a old and dilapidated mansion in London. He has an assistant, Darius who runs errands for him.
