The mom who drives all the kids to go surfing. And sometimes shreds themselves too.

Grommash "Grom" Hellscream was the chieftain of the Warsong Clan, and best friend and chief advisor to Warchief Thrall. He was one of the chieftains who had gladly taken the blood of Mannoroth the Destructor, thus binding the Horde to the Burning Legion — and he would eventually pay the ultimate price to free himself from the curse.
In many ways, the curse of our people began and ended with Grom Hellscream. His name meant "Giant's Heart" in our ancient tongue. He earned that name a hundred fold as he stood alone before the demon Mannoroth — and won our freedom with his blood.
