The Ghost/Plague Rat Style
Plague Rat Style in a nutshell: In Autochthonia there are only a handful of biological species other than humans: flees, bedbugs, lice, fruit flies, blowflies, spiders, many hundreds of kinds of bacteria, but of the mammalian orders there is only one: the Rat. Even as those in creation have developed fighting styles emulating snakes, monkeys, tigers, the praying mantis, and many other animals Plague Rat Style emulates the rats of Autochthonia. The base charm of this style allows you to develop a bond to a rat as your familiar, granting the practitioners access to a few more precious motes and a cunning scout who can go places you cannot and hunt out secrets. The early charms of the style then focus on not being seen, living in a hostile environment, and surviving sickness. Those that develop further master the form type charm which enhances all of the other charms in the style and gifts the practitioner with a rat's ability to function in total darkness and fight with much larger opponents. Developing your mastery still further allows the practitioner to serve as a carrier to plagues and inflict them on his opponents, while other charms in the tree allow you to increase your damage when using unarmed attacks and form weapons, and to wriggle your way through small spaces where you normally could not fit. The Capstone charm of the style allows the practitioner to use not just his familiar but any rat as his spy, taking on the properties of a mythical 'Rat King'. The Form weapons of Plague Rat Style are the knife, needle, and blowgun, which are treated as unarmed attacks for the purposes of it's charms. It may not be practiced in armor*.
*(Important Footnote: Before the Extinction of the Rat Cavalry of Estasia there was a charm which allowed PRS practitioners to learn to use the style armored, but this charm is no longer part of the style since to learn it you had to observe the Rat Cavalry in action. If the Autochthonians return to creation and discover a new breed of ROUSes this charm might be restored to the style.)
