Xi (pronounced "Shi") was raised by monks since infancy.  They expected her to be either fast as the wind, or invisibly stealthy, and she's kept to that habit.

She's quiet, not accustomed to speaking or being around other people.  Xi may seem standoffish, but she's actually friendly.

OOC/Xi serves as an AC tank, so if you need one in your party and see her alone, feel free to approach her.
