The First Doctor, Steven and Dodo land in the Tibetan Himalayas in 1630 AD, and travel with pilgrims to Det-Sen Monastery.
Tropes
- The Beastmaster: A minor example; Dodo is taught a secret chant that allows her to ask the Yeti for help.
- Blue-and-Orange Morality: Discussed when Steven and Pema discuss their contrasting cultural views on death.
- Chekhov's Skill: Dodo is taught a secret chant early in her time with the pilgrims that she is later able to use to ask the Yeti for help rescuing the monastery.
- Oop North: This story gives Dodo a Manchester accent, which she had in her debut story "The Massacre", rather than the Received Pronunciation she spoke for the majority of her time on the show.
- Prequel: To the televised adventure "The Abominable Snowmen", broadcast 54 years earlier. Set 300 years before the TV story, it serves as the Doctor's previous, unseen visit to Det-Sen Monastery that was referenced in "The Abominable Snowmen".
- The Reveal: Oddiyāna is Padmasambhava from "The Abominable Snowmen".
- Saying Too Much: Steven realises that the bandits had an inside man among the pilgrims when Pema mentions the lead bandit by name when she couldn't have known such information.
