Kargath Bladefist. Каргат Острорук.

Kargath Bladefist.
Shattered Hand Clan Leader
Kargath fought for survival in the blood-washed gladiatorial arena of the Draenor ogres.
  Every day of his life brought only new torment.
  The ongoing fighting and torture almost drove him to madness.
  Having lost the last grain of hope, Kargat smashed his hand,
  to break free of chains. Other captives followed his example,
  ready to make this sacrifice for freedom,
  and together they formed the Shattered Hand clan.
  Having become the leader of the clan, the former slave attached a blade to his cult,
  why he received the nickname Bladefist.
