Castle walls.

A hail fire of arrows rains down every thirty seconds resulting in a mass of flesh and armor nailed together by vile velocity. The ramparts shake considerably as the ram slams the doors of the castle. Enemy soldiers pour onto the walls like floodwaters, bringing with them a frenzy. You join the fray, brandishing your sword into the guts of many a foe. A stray arrow finds its way to your leg, then a sword from your left undefended guard, then, nothing.
