Antagonist: A role playing game of manipulation, wealth and war

Publisher's blurb:

Antagonist is the core rule book for a role playing game in which players take on the roles of morally gray characters of notable import embedded within an aggressively expansionistic empire. Staples of the sword and sorcery genre share the stage with big picture political and economic conflict, with the game going even so far as providing combat systems for social and economic warfare. This expands the gamut of available characters, allowing merchant princes and courtiers to work in groups with warriors and wizards towards a common goal.
