There are many different kinds of mercenary, but perhaps the most feared are the bounty hunters who ask no questions: The United League of Bondsmen.
A Bondsman may tell you he is part of a great tradition of hunting down transgressors and dangerous criminals, but the truth is quite different. Their only qualification is brutality, martial skill and a complete lack of moral qualms. Officially they are bounty hunters and thief takers. In reality more often than not they are slave-catchers, assassins and hired muscle.
Their motto speaks for itself. For the Bondsman, cash talks, and the question “why?” is a mere formality.
