"I'm not sure if Bones told you but I am related to Doc, his younger brother to be exact... You and I share a similar objective you see. Unfortunately, due to a great portion of the Chibiwanbanshu going rogue, I've had to lay low for a while for safety reasons..."
He reaches into his uniform to produce a long pipe and some tobacco.
"I started trailing the two of you in secret since you entered the grotto. I was also there in the Catacombs. Your little theft has drawn unwanted attention by a certain organization with powerful connections, both material and otherwise...."
With a flick of his thumb he lights the pipe and takes a puff.
"As it stands it is unsafe for either of you in the market or slums. On top of the Chibiwanbanshu after your heads, the cabal whose book you stole has hired on Chikuza muscle to tear the place apart. They're promising a hefty reward for turning you two in, double if alive."
