GMNPC for an UWi tabletop game, a page named Snow-on-the-Sills

she uses a shield to keep the idiots from getting killed and heals them when it happens anyway

as a Page she is only visible when people notice her, which, as a GMNPC and a slave, is also exactly mechanically how she should work

she stands in the back of the party and no one remembers she exists until she needs to do something! yay.
