Sellsword

From publisher blurb: Mercenaries, soldiers of fortune, scum of the earth; the Sellsword goes by many names. Driven by a thirst for gold and plunder, they’ll go to war for anyone so long as the price is right. While this fluid loyalty gives them a bad reputation among respectable circles, there are few who would deny their usefulness in times of strife. When war is a foot, a troop of skilled Sellswords can make the difference between victory in war and the shame of defeat. Just make sure they’re well paid. It’d be a shame to find their swords in your back.
