Xi is an enigmatic wander of the northern badlands. Xi speaks through the electronic box of tricks included as a part of that re-breather unit. The net result of this is that everyone assumes that Xi is male. No one every remembers seeing Xi without the mask on.
Xi is dab hand with the shotgun, often holding the trigger down and working the action. Pretty good with the sword too. As far as such things go, Xi is fairly well sought after as a wasteland hired gun. Xi can be contacted via Fon.
Xi takes payment in paper, writing implements, printed material and medical supplies. If these things are not available, then Xi won't take the job.
As part of a team, Xi will not do the cooking, but will stand a double watch without flagging. No gang with Xi in it has ever been surprised in the badlands.
