Overseeing and You: Making the Right Choices is a collection quest, having players collect 10 and the from Tyrantus in Eco-Dome Farfield in Netherstorm. Available at friendly reputation with Netherwing after completing 
You will need:
So you're the new overseer, eh? Well there's one thing any good overseer needs and that's the proper disciplinary weapon. Before you can go out there and knock some sense into these peons you need to have your "piece". Each overseer has to gather the materials required to make their own "piece" and you'll be no different.
I'll need knothide leather and the hardened hide of Tyrantus. You'll find Tyrantus in Eco-Dome Farfield, located in the northern reaches of Netherstorm.
Tyrantus is a Devilsaur and is easily soloable, roughly 10,000 HP. It'll take most players longer to get to him from the base camp than to kill him. You will have to ask a person with the skinning skill or buy the Knotehid Leather from an auction house.

There's peons to be disciplined, <name>! Hurry it up!
ARRR! You might make it as an overseer after all. That oversized lizard has been the bane of many an orc!
