Port to Everywhere - Dresden Files
Kyoko is a member of a supernatural faction named the Jade Wardens. Their primary job is to keep the Jade Court vampires in check. Their secondary role revolves around keeping peace between the various supernatural factions. They do this by being the middle man in situations where others can’t be trusted. They offer their wisdom and protection to any who request it. They also perform a tertiary role of information gathering and intelligence. It is in this last regard, that most other supernatural factions inquire of them.
As a teenager, Kyoko was pushed into the duty of being a Jade Warden on essentially the front line in Asia. There she learned the gritty truth about what vampires were capable of and how they needed to be dealt with. This helps her keep perspective on her primary job. While she is no longer on the front lines, she’ll remain vigilant in her duties to stop malicious vampire behavior so it never gets to the point it was in her past. This leads her to help solve problems before they occur following her secondary function. Wherever there is conflict, there must be a Jade Warden to mediate it. By developing relationships with many people and getting their respect, she can fill this position when the time comes. She also carries her sword to signify her station to others. A powerful weapon can be used just as much to slash a foe as to deter them from entering conflict in the first place. Lastly, her shape shifting powers allow her to become an amazing intelligence gatherer with almost no risk to herself. Allowing her to keep an eye on every angle possible.
