There's a low whistle from up inside a tree.
"You are a big boy!" a female voice, full of mirth, speaks. The leaves rustle. A woman falls into view. She's short, has long brown hair tied back in a tail, and looks very Greek. "A big boy with a lot of kin."
She pauses and shifts to Lupus form, jet black with light grey dapples. "Welcome to Falling Waters, Serebro. I'm Quills. The Warders will check you over, give your kin a good sniff, and over the Falls you go. If you have no taint in soul or body, you're free to join up. If not, our lady Maid of the Mist will deal with you."
