Battle Amber

From publisher blurb: Turmoil grips a low tech planet as one of its nobles embarks on a spree of conquest using a wondrous substance he recently came into possession of. The same substance which rumors have reached the ambitious CEO of an interstellar company, who sends the PCs to fetch for him. But the heroes quickly discover that “primitive” doesn't mean “stupid”, and in fact can instead mean “deadly.” Battle Amber is a short adventure for Cepheus Engine and the Original Science Fiction Roleplaying Game.
