Farrash was a planet visited by the Fourth Doctor and Sarah Jane Smith. The radiation from one of the suns had changed, and over the course of a hundred years, the Farrashians were slowly becoming sterile.
Different factions on the planet tried to find a solution to the problem. One group, with the support of the Leader, planned to use aborted foetuses to animate mechanical bodies. Another group, to which Fraal belonged, experimented on animals. A third group built a twenty-foot-robot as a prototype.
During the Farrash Future Ratification Assessment Committee meeting, the giant robot went out of control, killing the Leader and injuring many others. After order was restored, The Doctor advised the survivors to pool their resources to solve their problem. (Rights)
