Second Nestene invasion of Earth

The second Nestene invasion of Earth (PROSE: Doctor Who and the Terror of the Autons) was the second attempt by the Nestene Consciousness and its Autons to conquer Earth, with the aid of the Master.

Having stolen the only intact energy unit leftover from their first invasion in October, which was named "Black Thursday" afterwards, the Master made contact with the Nestenes in early Summer and began manufacturing Autons and auto-jets, his own contribution to the invasion, using the plastics factory of Rex Farrel. An Auton Leader spoke for the Nestene High Command, and warned the Master not to let his feud with the Third Doctor cause the invasion to fail.

Hundreds of people were killed prematurely by the auto-jets, but a million units were distributed in the guise of plastic daffodils; the Nestenes assault force would land and send a signal, killing people across Great Britain and using the chaos and confusion to invade. During a battle between the Autons and UNIT, the Master opened a channel to the Nestene home world and a massive Nestene creature began to materialise. Convinced by the Doctor that the Nestenes would kill him as well, the Master and he worked together to reverse the polarity of the transfer shaft, sending the Nestenes back into space.
