From publisher blurb: The writings of a sacred text reach across thousands of years to stir the faithful of the present day. The deeply devout Kumrini heed the call to kill all nonbelievers, striking out against offworlders and forcing the PCs -- onworld participating in an archaeological study -- to flee for their lives across harsh terrain one step ahead of fanatics seeking to offer their heads in sacrifice to the dread god Ku. Sacred Duty 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.
