SCAB!
The setting is a generic fantasy world called Grimwold, filled with Evil Lords doing evil things, and the Heroes who try to stop them. So it has been for time immemorial.
Recently, though, this simple routine has been thrown into chaos, as all of the Minions of the Dark Lords have Unionized and gone on Strike. Tired of low pay and no gratitude, the Minions take to the picket lines, threatening to bring the Cycle of Good versus Evil to a grinding halt.
This can not be! With no easy resolution to the labor dispute in sight, the Dark Lords have but one choice.
They turn to the Scabs.
You are a Scab. A nobody, a nothing. You're not strong enough to be a warrior, not smart enough to be a wizard, and not quick enough to be rogue. But maybe - just maybe - you might be good enough to fill the shoes of a picketing Goblin.
It's not easy, though. Every day you have to brave the picket lines, do the evil bidding of the Dark Lords, and not get squashed by the Heroes who keep showing up. Worst of all, you have to dress and act the part. But hey, it's a job.
