Equilibrium (audio story)

 was the one hundred and ninety-sixth story in Big Finish Productions' monthly range. It continued a trilogy of the Fifth Doctor's return to E-Space that began in the previous story, Mistfall.

Publisher's summary
Still looking for a way out of E-Space, the TARDIS crashes to Isenfel - a realm of snow and ice. Snarling beasts stalk the frozen plains, a feisty princess leads the hunt, and a queen in an ice palace rules over her loyal subjects.

But this is no fairytale kingdom, and everyone in Isenfel knows the price of survival. While Nyssa and Tegan uncover deadly secrets hidden in the palace, Turlough flees for his life across the tundra.

And as for the Doctor... he only ever wants to change things for the better. But in a world such as Isenfel, such a hope may not even be possible.
