Troy Game

 was an inhabitant of Caresh.

Whilst trying to escape the Furies sent to kill Lord Roche, Game was taken accidentally to 1999 Earth in his TARDIS. She got temporary amnesia and was taken in by Simon Haldane. She eventually recovered her memories and was returned to Caresh by the Third Doctor. After her planet was saved, she went into the next stage of her development, growing gills and living in the ocean. (PROSE: The Suns of Caresh)
