Disarmed!

Objectives
in Dalaran City wants you to return the Severed Arm to her.
 * Severed Arm

Description
I've received word of an unfortunate accident at the Dalaran prison; a guard had his arm severed and thrown into the water by a particularly vicious inmate.

Our first aid clinic promises they can reattach the arm if we bring it back.

You fish long enough in the water outside the prison, and I'd bet my favorite fishing pole that arm will surface. Find that arm, and bring it to Olisarra the Kind here in Dalaran. She'll know what to do.

Progress
Hi there. Do you have something for me?

Completion
Oh, hello there. Marcia said that you'd be coming by with that poor man's missing arm.

She also gave me this bag to give you as a reward. It smells horrible, and I'm anxious to make the trade if you don't mind.
