The Eris Accord

From publisher blurb:

A pacifist world, a ruthless rival, and a trade deal hanging by a thread! When merchant Arnid Rusten finally secures negotiations with the elusive Sereni, he hires the adventurers to serve as his aides and protection. The catch? Violence is forbidden, the atmosphere is mildly sedative, and an old enemy is hellbent on sabotage. As talks unfold in a haze of diplomacy and danger, the heroes must keep the peace, expose sabotage, and stop an armed assault — without being seen breaking the rules.

The Eris Accord is a short science fiction adventure for RPGs using a 2D6 engine, such as Cepheus Engine and the Original Science Fiction Roleplaying Game. Other systems are easily adapted.
