This module works as a toolbox to adapt the core mechanics from The Legacy of Cthulhu to pre-apocalypse settings. You will find usage for currency, housing, enemies, modifiers for specific rules, and a unique set of tiles (including warzone and expedition tiles) that allow deeper customization to the game, even allowing you to adapt the setting to other historical moments – imagine fighting Cthulhu in the old west, cold war or inside a space station!
