Of Swords and Honour
Black Gate Ninja Guild
The Ninja of the Black Gate are one of the most mysterious Ninja in terms of their methods. They exist behind the scenes, manipulating society to suit the aims of their patrons.
They are often found servings as courtiers, geisha and advisors in many courts. Daimyo and nobles try to root them out as best they, but one can never be truly certain that they are all gone.
They never kill anyone overtly, using physical means anyway. They work by undermining a persons social standing, honour (which are as good as killing someone) or by manipulating someone else ing to kill them.
They seem to possess some form of minor shapeshifting which allows them to alter their physical appearance and also seem to be able to use some sort of magical suggestion on their victims.
