Convicts and Cthulhu is a Call of Cthulhu supplement set in the Australian Penal Colony. From the product description:
Convicts & Cthulhu is a sourcebook designed to allow Call of Cthulhu Keepers and players to run scenarios and campaigns set in the penal colonies of early Australia. It particularly targets the historical period from 1795 to 1810, a time in which law and order played second-fiddle to greed and corruption. This was the depraved era which led ultimately to Australia’s first (and only) military uprising: the Rum Rebellion!
Lady Blackbird is a free RPG module and fast play rules set with a steampunk flavor. From the introduction:
Lady Blackbird is on the run from an arranged marriage to Count Carlowe. She hired a smuggler skyship, The Owl, to take her from her palace on the Imperial world of Ilysium to the far reaches of the Remnants, so she could be with her once secret lover: the pirate king Uriah Flint.
HOWEVER, just before reaching the halfway point of Haven, The Owl was pursued and captured by the Imperial cruiser Hand of Sorrow, under charges of flying a false flag.
EVEN NOW, Lady Blackbird, her bodyguard, and the crew of The Owl are detained in the brig, while the Imperial commander runs the smuggler ship’s registry over the wireless. It’s only a matter of time before they discover the outstanding warrants and learn that The Owl is owned by none other than the infamous outcast, Cyrus Vance.
