Witchers

*Not to be confused with Witch Hunters* While similar in purpose, Witchers have devolved, or evolved depending on who you ask, into non-government hunters preferring to demand coin for their services.

The Order of Witchers was an attempt made by kings and affiliated mages to create an order of magic-using knights who would help the The Empire get rid of enemies they hadn't otherwise been able to subjugate, enclose in reservations, or exterminate – monsters. The final outcome of the mutations disappointed most of the mages, who began to call the result "witchers", charlatans capable of nothing more than mere witchery. A few renegades however,secretly aided the monarchs interested in continuing the experiment, and the final set of Trials and Mutations was established.
The Order didn't last long however – its members had abandoned most of the original "knightly" values over time and soon split into a handful of witcher schools, aimed at taking a more professional approach to eradicating monsters.
