'Running Wild': 'Tholos' by Alex Hewittt

Pursued across space and time by the relentless Cosmogon, and determined to uncover the truth behind her own origins, the Doctor unearths dangerous revelations that could change everything she believes about herself.

Some mysteries were never meant to be solved.

To uncover the secrets hidden within her mind, the Doctor voyages to the Temple of Lucidity - a great tholos floating through space - where a multicoloured tiger will teach her the secrets of the mystical dream-language of Oneira.

But are the Arkiris Tiger's motives pure? How has the Doctor's dogged pursuer, Cosmogon, managed to follow her here? And why does Cosmo have a new face?
