Power Behind the throne is a short scenario by Carl Sarent. It is a scenario where the PCs rub elbows with nobles, much like in Edge of Night. It is set in Middenheim.
As it was shoehorned into The Enemy WIthin series, late in the series, it didn't see a lot of play for most groups.
The copy I have, is the 1988 hardcover by GW.
There's one thing I can't figure out: What the hell is the guy with red clothes and green armor doing on the back? Is he a cutout of artwork from somewhere?
