Archimedes 7 is a colony ship traveling from our solar system to a distant world.
A small piece of tin protecting its inhabitants from the dangers of the void.
But the real danger is already inside the ship.
Archimedes 7 is the final chapter in a series of Call of Cthulhu scenarios all linked by the Yellow Sign. The Curse of the Yellow Sign scenarios contain no blasphemous books, no monsters, no cultists and no Library Use rolls. Only ordinary humans confronted with the true nature of the universe. They are designed to be played in a single evening with limited preparation and maximum impact, filled with the kind of ruthless game master techniques you expect from John Wick.
Archimedes 7 contains:
* a map of the ship
* 6 pre-generated characters
* Tons of advice and playtest notes
