The Trolls

    • Lesser leaders include: Vanira the shaman and Zen'tabra the druid
  • Capital is Darkspear Isle, the largest of the Echo Isles, off the coast of Durotar.

  • The trolls use raptors and bats as riding mounts.
  • They left Orgrimmar in Cataclysm, and do not support Garrosh.

The Orcs

• The orcs of Durotar.
  • The surviving orcs of Azeroth's First, Second and Third Wars, who were released by Thrall from the Internment camps and led by him to form their new destiny in Kalimdor while attempting to embrace their once honorable, shamanistic ways and fight the corruption of demonic magic.
  • Led by Warchief Garrosh Hellscream, named by Thrall to succeed him in the wake of the Cataclysm.
    • Lesser leaders include: Varok Saurfang and Drek'Thar.

The Hordes

The Horde is one of the two major political factions of the mortal races in Azeroth, its counterpart being the Alliance. The Horde, a faction led by off-worlders and composed of outsiders has survived these obstacles by making allies with few of the native races of Azeroth or even uneasy allies. Although its ideals, policies, and beliefs have been revised and membership has changed over time, it is the same Horde inherited by Thrall through Warchief Orgrim Doomhammer.. However, since the mantle of Warchief was passed on to Garrosh Hellscream, the Horde's alliance with other races has began to suffer heavily due to Garrosh's warmongering. A direct example of this are the Troll's under Vol'jin leaving Orgrimmar because of Garrosh's hunger for war and Sylvanas Windrunner ignoring the warchiefs commands and using her plague on her enemies.

Other Alliance Forces
