Grom sneered, "What, afraid to accept my challenge? Fear that I'll gut you? If you voluntarily leave the Horde, I'll spare your life!"
This was a hard slap to the face, and Blackhand could no longer tolerate it. "You've asked for it, Grom. I accept your challenge, not because you deserve it, but because I want to kill you with my own hands and dig your broken brain out of your skull. Take out your battle axe! No need for the dueling grounds, we'll settle this right here."
The Destroyer, Blackhand, was no ordinary figure; although courageous and reckless, he became Warchief not only through the formidable strength of the Blackrock Clan but also through his own immense power.
Historically, Orgrim Doomhammer dared to challenge only after Blackhand was injured and defeated, hence his nickname "Backstabber."
Though Hell Scream was powerful historically, he was willing to accept Blackhand's leadership, making it clear that even Hell Scream acknowledged Blackhand's strength.
