From publisher blurb: The heroes find themselves in a desperate race against time to deliver an antidote for a planetary leader who was supposed to bring an end to a brutal civil war but who’s instead been poisoned by political enemies. In the adventurers’ hands is no less than the life of a valued ally of the interstellar government and the prospect of a rekindled war. Antivenin is a one-page, no-frills adventure for Cepheus Engine and other tabletop RPG science fiction games using a 2D6 mechanic (including The Original 2D6 Science Fiction Game) starring characters of varied career backgrounds.
