Our group has been playing one continuous Space 1889 campaign on and off since 1990. Now we have reached 1898, though only two PCs have been along for the whole ride. We have played a group of Swedish and Russian aristocrats with retinues, serving Monarch and Motherland in distant dangerous places.
However, I have recently decided to make a mood reboot. In 2019, I will start a new story arch that focuses on fighting the rapacious regime of Leopold II, king of the Belgians and of the Congo Free State in the Coprates. His activities have so far not figured in our campaign, because its adventures have mainly been located in the Parhoon/Syrtis/Gorklimsk region.
The players will create new characters that come from the middle and lower classes, and who are working for a Martian equivalent of the Congo Reform Association, though with more guts and glory. I have decided that in our timeline, the Coprates Colony is owned by the Congo Free State government in order to make it a more fearsome and despicable antagonist. The PCs are financed by American philanthropists who wish to see an end to Leopold’s abominable exploitation of the natives. The PCs have a fairly free hand to achieve this, since their faraway benefactors are shielded by a plausible deniability setup. More old-school Mission Impossible and Indiana Jones than Edmund Dene Morel — punching Congostaters is a good and righteous deed.
