Putting Dwarves in a Trenchcoat

From the introduction: Two dwarves in a trenchcoat trying to sneak into a bar. Two dwarves in a trenchcoat dash across the battlefield screaming and goblins flee before them. Then they fall over and get tangled in the coat, swinging their axes wildly. Stealthily observing the goings-on of the marketplace through some holes cut in a newspaper. An alternative rules system to make stealth narrative-driven.
