Drummond was an Earth colony planet in the far future where the population were attached to their personal computers all day, Rene.net being the main data network. Homeless people would rob food from Drummond Wholesale.
Using Rania Chuma and the Rene.net, Sutekh briefly altered reality to turn Drummond into the "the new Phaester Osiris." The Fourth Doctor and Leela defeated Sutekh, and Drummond was returned to normal using people's memories. (AUDIO: Kill the Doctor! / The Age of Sutekh)
