Simia KK98

Simia KK98 was one of the few Gallifreyan colonies. Another was Dronid.

Geography
Simia KK98's psychedelic sky and landscape caused most humanoids to hallucinate. The planet was uninhabited before colonisation, although the planet did support basic fungal life. The Time Lords built numerous rocky fortresses on its surface, plus one huge central city. There was a six-armed statue of Rassilon outside the fortress, which housed the entrance to a bottle universe. (PROSE: Dead Romance)

History
The Time Lords grew the sentient Type 103 TARDIS Marie on Simia KK98. Homunculette and his Chapter House once spent months on Simia KK98 sealed in the silos beneath the permafrost waiting for the Enemy's probes to finish scanning the surface. (PROSE: Alien Bodies)
