While Seth and Teka worry about finding an exit from the maze, the Doctor and Romana are more interested in finding what is at the center of the maze, and at the heart of the Nimon’s operation. What they find there is a room full of equipment for diverting immense amounts of power to a matter transmitter. He and his friends then have to hide as the Nimon itself approaches, operating the equipment now that it has the tribute from Aneth to bring his complex up to full power. A pod appears in the transmat chamber, carrying two more Nimon, with more to come. The tributes of slaves and material from Skonnos are merely helping the Nimon’s own invasion plans, which will not benefit Skonnos in any way. Once the Nimon have left, Romana sits in the transmat pod to analyze it, and is accidentally sent to Crinoth, the Nimon’s home world.
