Nature and Demeanor
Everyone plays a role, often several, every day. Every individual displays multiple layers of personality, varying from the contrived to the sincere. Each of these roles defines how we interact with the people and the places around us, and we choose which parts of ourselves we wish to show.
It's the same with hunters. The concept of Nature and Demeanor corresponds directly to the different masks we wear when we interact. Your hunter's Nature is their true self, their innermost being -- the person they truly are. It's dangerous to show this, though, as it lets others know who we are and what's important to us. Thus, your character also has a Demeanor, a face they show to the world. By choosing how we relate to the world, we're able to choose how it relates to us; we guide the responses others give us.
Nature and Demeanor are usually strikingly different for the imbued. Trying to maintain any semblance of a normal life -- and then confronting the unknown -- makes for a schizophrenic existence. Maintaining contrasting Natures and Demeanors helps draw the lines between identities: Every-day person versus potential killer. And yet there are those who take the hunt so far that it consumes all of their identities. Nothing else has meaning to these people, who develop the same Nature and Demeanor -- and are watched closely by their allies for signs of going too far and becoming a liability.
Even if your character strives to show separate faces to the world, the lines must sometimes blur. The shadows and their agents are everywhere, operating by night and day. They can be at work, on the street, at the gym, or even in the home. The truly wary never let down their guard and frequently wear their hunter face for fear of showing weakness -- which could lead to death.
These archetypes allow you to build a sense of personality for your character, and to define a bit of what makes them tick. Yet Archetypes aren't rigid; characters need not devote to themselves slavishly to their Natures and Demeanors. Rather, your character should act as you reasonably or emotionally believe they would act in a given situation. You can come up with your own Archetypes that more closely define how your character responds to their world. After all, every character is an individual, and customized Archetypes are a logical outgrowth of a well-rounded character. Below are just some basic character Archetypes.
