An assassin is a master of the art of killing, a vicious weapon honed by experience and inclination to learn the myriad ways to end a life. Unlike common warriors or rogues, an Assassin does not study various fighting arts or muddle his training with martial dirty tricks, he instead studies the anatomy of the various creatures of wildly different anatomies and forms of existence, and he uses this knowledge to place his blows in areas vital for biological or mystical reasons. Stealth and sudden violence are his hallmarks, and various exotic tools and killing methods become his tools.
While most societies consider assassination to be a vile art, or at best a dishonorable or unvalorous one, the reasons that drive these killers vary. Cold-hearted mercenaries share a skill set with dedicated demon-hunters, differing only in the application of their skills. Only the most naïve student of ethics believes that all killing is evil, or that nobility cannot be found in a mercifully quick death.
