Ryklan

Ryklan was a planet colonised by humans. The crew who arrived to build a city for the colonists were being killed by the Calendar Man, with only Olivia Pamiec remembering the victims, until the Eleventh Doctor and Amy Pond arrived. Olivia stopped the Calendar Man and remained on Ryklan to continue helping out rather than joining the two travellers in the TARDIS. (AUDIO: The Calendar Man)
