Conan Against Darkness! is a 1984 adventure module for the first edition of the Advanced Dungeons & Dragons fantasy roleplaying game, set in the Hyborian universe of Robert E. Howard's character Conan the Barbarian. It is designed for four player characters at character level 10-14 and uses some minor rule variations in an attempt to recreate the setting's atmosphere. It was publicized as containing a "journey of epic proportions".
