It's a Trap!

There's nothing more that I hate in this world than the sons of Gruul and their father! They slaughtered my people, and my children, and now I will have a taste of revenge! I have fashioned a trap from some dragon fire, and if you're clever enough, you might just be able to use it to kill a gronn. I'm sure that you have a particular gronn in mind; it matters not to me which one you kill. Just hurry, take the trap to your Commander Stonewall. My thirst for revenge must be quenched!
