From publisher blurb: When the adventurers accept a job to find and rescue a noble's daughter from a repressive world, they quickly find themselves immersed in a battle between a secular messianic figure and the fundamentalist society that wants to execute him on charges of heresy. Ex Scientia 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 Roleplaying Game), starring characters of varied career backgrounds.
