After listening to the last episode of the Fear the Boot podcast, I've become intrigued by the possibilities presented by the Progress Clock mechanic used in John Harper's Blades in the Dark RPG.

So I'm planning a one-shot for the rpgconvention in my town in a few weeks, and I'm thinking of making it happen in a Bermuda triangle/Demon's Sea/Sargasso Sea equivalent in Theah, with maybe a cemetery of ghost ships, a few marine monsters and some strange Syrneth artifact that makes the PC get there against their will...

Thing is... was there ever something of the like in the 1st edition??
