Member races of the Burning Legion are countless – Titans, Man’ari, Eredar, Wrathguards, Nathrezim, Annihilan, Doomguards, Doomlords, Mo’arg, Shivarra, and many more. They’re mainly warlocks – spell-casters that have the ability to summon demonic minions. Legion has a specific hierarchy. So, Eredars have become overlords of the Legion. Pit lords are generals and commanders. Doomguards are captains, marines, and military leaders. Felguards are mostly soldiers, and so on.
