Slavelords of Cydonia
An adventure sourcebook for Grim Tales, this campaign pits heroes against tentacled horrors from beyond the stars in a world-spanning struggle to prevent a second cataclysmic war. It presents a complete campaign for characters from level 1 through 20, set in a time and place chosen by the Game Master. Additional material includes new monsters, spells, technology, races, feats, and talents for use in other Grim Tales campaigns. The content is compatible with the latest edition of the world's most popular roleplaying game and can be used with or without the Grim Tales campaign rulebook.
