Deliver the Dragonfire Trap to Rexxar at Thunderlord Stronghold in the Blade's Edge Mountains.
There's is no cause of fury greater in this world than that of Gruul and his sons. They slaughtered my people - my children - and now I will have revenge.
I have fashioned a trap from dragon fire, and if you're clever enough, you can use it to kill even a gronn.
Just hurry, take the trap to Rexxar. My thirst for revenge must be quenched.
