On a world where vicious beasts stalk ancient ruins, Professor Song teaches a student the finer points of archaeology.
But then she meets an incarnation of the Master who is desperate to survive.
And if they are going to escape this place alive, they all must work together.
Tropes:
- Blood Knight: The Therians live to hunt like animals.
- Enemy Mine: The Master is forced to work with River to go to Cheska Minor and retrieve his TARDIS.
- No-Sell: River Song is not affected by the Master's attempt to hypnotize her.
- Our Werewolves Are Different: The Therians are werewolf-like creatures who live on Cheska Minor and used to be ruled by the Master. The Master has built a device to put the whole planet in eternal daylight to keep them human, but they created glasses to allow them to assume their bestial forms.
