From the introduction: This Ticket of Leave supplement provides information about some of the early scientific expeditions that were sent to explore the Blue Mountains. It provides background details of some of the scientificallyminded colonial officials of the day, as well as details of the rugged unexplored interior they were charged with exploring. It also provides a detailed outline of a scenario which allows your Convicts & Cthulhu investigators to take part in a most unusual scientific expedition – all thanks to a curious meteorite which is believed to have come to ground in the remote western reaches of the colony.
