On Deva Loka, a sylvan paradise planet with no predators, diseases or civilized roadways, Nyssa (due to Monarch's two attempts to turn her into an android) stays in the TARDIS to fully recover from mild mental disorientation, under the Doctor's Delta Wave Augmenter while the others go exploring. The Doctor and Adric find a survey team assessing the planet for colonization, and cracking under the stress of three fellow members (half the crew) disappearing without a trace. There's also a primitive and almost entirely speechless native culture on hand who curiously have about them a few items of technically advanced skill and knowledge. Meanwhile Tegan succumbs to a dreaming tree where an evil entity awaits a catalyst for entering the real world. Written by

The story is a striking allegory for Australian colonialism. It is unclear if this is intentional but there are many striking similarities between both The Kinda themselves and their colonisers and those of The Australian Aboriginal people and theirs. The automatic dismissal of their status and intelligence (out of ignorance or indifference). Similar kinship systems are also reflected. The period of creation in Aboriginal lore is also known as the Dreamtime or the Dreaming and the snake/serpent is a promenent feature. See more
