Vernon Allen was a dream co-ordinator on Unicepter IV.
Unknown to him, his slinth Miki was taking advantage of the shared dreams he was creating to generate nightmares and feed off the fear of the dreamers. After the Fourth Doctor stopped Miki and the other slinths, Allen lost his job and started looking for a new one. The Doctor's companion Sharon Davies decided to stay on the planet with him.
