Ritsy Delivery

You need to be level 85 and have completed A Rodent Problem questline from Paineel.

Ritsy is in the far back of the 2nd level of the Roekillik caves, past the crystal people. There are two ways to get to him, either run through the caves and do some fancy climbing to get up the little ledge or put on your floaty cloak and jump to the back door. If you opt to jump, go to 945, -48, 3058

Ritsy tells you she is waiting on a delivery from her bretheren. Go kill the courier which spawns in various locations in the cave, I happened to find one right near Ritsy. Take the package back to Ritsy which completes the quest.
