Written by Robin Mukherjee, this three-part story had been considered for season 26 as the "spare" script should another planned story become no longer suitable. The adventure was to take place on a monastic planet inhabited by humans and large beetles. The humans were monks who worked to provide a special elixir that enhanced intelligence. This elixir would be produced by the beetles feeding on intelligent beings. The abbot of the monastery wants to feed the Doctor to the beetles in order to produce a more potent elixir for himself. The script was not completed beyond a partial storyline. Mukherjee was unsure how events would have been resolved beyond a contest of wills between the Doctor and the abbot.
