Polarity

From publisher blurb:

Since the ruler of Daxolo died and his heir proved to be unfit to rule, the political situation has devolved into legions of strongmen fighting one another for the chance to rule, and looking for any edge that can help them. One of them has taken to gathering subjects — willing and otherwise — for an experiment designed to give him that edge. But one of his abductees draws the heroes into the situation, where they find themselves facing a perfect combination of ambition, madness, and violence, and which might prove too much for them to handle.

Polarity is a short adventure for 2D6 science fiction RPGs such as Cepheus Engine and the Original Science Fiction Roleplaying Game.
