Defeat Horgrenn Hellcleave inside the Conquest Pit and speak to Bookie Vel'jen for a reward.
I'm gonna shoot straight with ya, kid. This next contender's a murderer.
He was to be executed last week, but he strangled the hangman with his left hand, so Krenna's guards sort of let me have him.
Feel free to pass on this one. I wouldn't blame ya.
