You hear it before you see it. The distinct sound of rushing water. A flash flood!

Shouting for the rest of your Free Company to take cover in the trees, you grip the slick black bark of the nearest limb and climb.

You make it only a dozen spans up the tree before the water hits. Rolling down from the mountains, a torrential wall of liquid, rock and mud crashes into you. Clinging to the trees, you wait for the initial wave to pass, then begin to pick your way carefully between the trees to the far side. It takes time, but it is better than falling into the swell below.
