The Gowenn people were a species which were consumed by their supposed saviours, the Sou(ou)shi. They had travelled to the Sou(ou)shi ship by means of a a small, aerodynamic shuttle with delta wings and clean titanium power units which was still present in the shuttle bay when the First Doctor visited the ship. In fact, the Doctor used this shuttle and some mm’x crystals to successfully escape the ship and survive a landing on Venus. (PROSE: Venusian Lullaby)
