From publisher blurb:
Skyfarer is set in the same universe as the space-set Sunless Skies, its nautical predecessor Sunless Sea and browser adventure Fallen London, all of which share a darkly twisted blend of Victorian steampunk and cosmic horror, and are described by developer Failbetter Games as ‘literary RPGs’.
In Skyfarer, players take on the roles of crewmembers of Sunless Skies’ steam-powered flying locomotives, from gunners and engineers to the pest-catching ship mascot, with the GM controlling the captain of the vessel. The catch is that the captain – for whatever reason the GM decides, from drunkenness to being nothing more than a hallucination – is unable to perform their normal duties, leaving the running of the ship up to the remaining crew.
One of Skyfarer’s core gameplay elements is tenacity, which is earned by characters acting according to their defining personal integrities and can lead to further inconvenience for the crew and story diversions on the whim of a die roll.
Skill checks using Skyfarer’s four character ability scores – ‘iron’, ‘mirrors’, ‘veils’ and ‘hearts’ – are performed with a d10 and the relevant modifier. Failure during particularly dangerous tasks can increase a character’s ‘peril’ – an overall measure of health, mental stability, luck and more that can ultimately result in a character landing themselves ‘in danger’ and ending up out of the story if another character is unable to save them. Spending tenacity can stop characters risking their lives – among other things.
