The Orcs

The Orcs were eventually led into Night Elf territory and fought several skirmishes against them as they attempted to set up camps. Here, the Pit Lord Mannoroth returned and tempted Grom Hellscream into drinking from corrupted waters, placing the Warsong Clan back under the corruption of the Burning Legion. Grom then led his clan on a warpath through Night Elf lands and slaughtered the demi-god Cenarius. However, Grom was eventually freed and atoned for his deeds by aiding Thrall in defeating Pit Lord Mannoroth, sacrificing himself in the process and liberating the Orcs from their blood pact.

The liberated Orcs set aside their differences with the Night Elves and Humans to help defeat Archimonde at the Battle for Hyjal Summit. The Orcs then set out to carve a place for themselves on Azeroth in Kalimdor. They called their new homeland Durotar, after Thrall's father, Durotan. Their capital city was named Orgrimmar, after Orgrim Doomhammer, the former War chief.

As of the present time, the following Orcish clans survive within the Horde under Thrall:

* The Frostwolf Clan
* The Warsong Clan
* The Bleeding Hollow Clan
* The Shattered Hand Clan

These Orc clans are merely examples of the very few numbers of Orcs who hold strong to their old shamanistic beliefs and clansmen ship. Almost all the original clans are divided among the different Hordes (the Fel Horde in Outland and the Blackrock Clan in Blackrock Mountain both consider themselves to be the "True Horde"). However almost all Frostwolves, Warsong and Bleeding Hollow orcs are in the New Horde, ruled by Thrall. All other orcs in the New Horde have given up their clan affiliations; apart from a few Shattered Hand orcs, who make up the Assassins of the New Horde. However, most Shattered Hand orcs belong to the Fel Horde in Outland ruled by Kargath Bladefist.
