Appearance:
She’s a deceptively short woman, and looks younger than her twenty-three years.  She tends to dress in sturdy black trousers and a gray-blue tunic.  She wears leather arm guards, similar to those used by falconers.  Her hair is an unusual blue-black shade, and falls to her shoulders when she wears it loose (most of the time).  Her bright green eyes greatly resemble a cat’s.

Background:

There was once a tribe of humans that was referred to as “the Wild Ones.”  The Wild Ones evidently had a peculiar link to the natural world around them; each person born in the tribe had an affinity for a particular type of animal.  This went far beyond “spirit animals” of other tribes.  The Wild Ones took on some of the physical characteristics and temperments of the animals.  It was also said that the Wild Ones could speak with them.  Of course, this is now dismissed as legend and myth, for the tribe of the Wild Ones was lost generations ago.

Which brings it to Jade.  Jade, unbeknownst to her, is one of the last descendents of the lost tribe, as is her older brother.  The bloodlines have of course thinned out, and any characteristics of the Wild Ones appear erratically within the family line, and are not as strong as the original tribe, but they are still there.  When Jade was born, her eyes were observed to greatly resemble a cat’s; she was also evidently blind for the first few weeks of her life.  (Her parents were not alarmed, having experienced much the same thing with her older brother).

Jade has an affinity for cats.  She has always been small, but is deceptively quick and agile.  Her sense of balance is incredible, her vision is exceptional (especially in the dark), and some of those who know her well tease her and say that she has nine lives.  This may or may not be true, for Jade also has a knack for getting herself into and out of very dangerous situations. 

Jade is afraid of dogs, and can be very aloof at times, but those who know her forgive her for it.  She is also very independent, and has a tendency to go wandering.  However, she is also very patient, and has been known to wait in hiding for hours for something she was watching.
Jade and her older brother Jeremiah are in the employ of a magician named Reyjen, as hunters and bodyguards.  Jade is a surprisingly tough woman, and many consistently underestimate her.  Jade considers Reyjen a very good friend, especially since he once saved her life, and the life of her brother.

Roleplaying Notes:

Anyone who spends enough time with Jade and is sufficiently familiar with the stories about the Wild Ones should eventually make the connection.
Jade, although she realizes that she’s odd, doesn’t really know that she is a Wild One. 

Jade’s peculiar nature might attract attention, which could be either very good or very bad, depending on the location and culture.

Perhaps the PCs might need the services of a very good hunter and/or tracker.  If they are well-enough known, and know the right people, Jade and her brother Jeremiah might be just the people they want.

Once a person has earned Jade’s trust (which is no small accomplishment), she can be one of the most loyal friends anyone can ever have.

Most people at first think that Jade is a child or a teenager, because of her size.  This almost always should lead to people underestimating her badly.  This woman isn’t the greatest fighter in the world, but she can and will kick major butt if she figures there’s a reason.
