Espero

Espero was a human colony in the 61st century that was once saved by the Eighth Doctor from an energy wave created by a Maker called Reo (PROSE: Halflife).

The Doctor later sent K9 to Espero in search of Madame Xing (PROSE: The Gallifrey Chronicles).

Geography
Countries on Espero included Anjon, which was ruled by a democratically elected Prime Administrator. There were eight nation states on Espero, all of which had proper democracies save for Saiarossa, which had a royal family. (PROSE: Halflife)

Flora and Fauna
Espero had indigenous insects. Other animals native to Espero included Burrowbears, which occasionally killed and ate humans, Mokeys, small monkey-like mammals often kept as pets, and tree-rats and creatures called Elephines which dwelt on the southern plains (PROSE: Halflife).
