Witch Hunter
Witch Hunters are Aware humans who are experts in killing and defeating Others and Practitioners that cross too many lines.
Advantages & Disadvantages
Being a normal person as opposed to a practitioner affords certain advantages, as Others cannot freely act upon them to a limitation. They can lie, and are freely allowed to invade demesnes without reservation because they aren't bound by the same rules as those who practice.
Their downside is that they are only human with few to none advantages beyond basic training and weaponry. Because they are informed of the supernatural it is hard to leave all that behind and live an ordinary life. Practitioners could very well be unhappy or unsettled by the appearance of witch hunters and Lords or local powers could seek to control them, even abuse them.
