The Warlords of Draenor.
The Warlords of Draenor were key orcs within the Iron Horde (minus Garrosh Hellscream). It consisted of Grommash Hellscream, Durotan, Blackhand, Ner'zhul, Gul'dan, Kilrogg Deadeye, and Kargath Bladefist. The seven orcs were famous throughout Draenor and Azeroth, Grom having slain Mannoroth, Durotan being the father of Thrall, Blackhand in being Warchief of the Iron Horde and the father of Rend Blackhand, Ner'zhul having opened the Dark Portal and being the first Lich King (created by Kil'jaeden), Gul'dan having slain Durotan (and his skull once held in the grasp of Illidan the Betrayer), Kilrogg Deadeye was mostly famous for his name being named after his one eye he lost, and Kargath Bladefist led the orcs of the Fel Horde and Shattered Hand Clan, as well as having a blade on his right hand.
